force ?
Answer:
F = [tex]\frac{-Gm_{1}m_{2} }{r^{2} }[/tex].
Explanation:
Gravitational force between two objects of masses [tex]m_{1}, m_{2}[/tex] kept at a distance r is given by the formula
F = [tex]\frac{-Gm_{1}m_{2} }{r^{2} }[/tex]
Here ,[tex]m_{1}[/tex] = 2m
[tex]m_{2}[/tex] = [tex]\frac{m}{2}[/tex]
Thus , F = [tex]\frac{-G.2m.\frac{m}{2} }{r^{2} }[/tex]
F = [tex]\frac{-Gm_{1}m_{2} }{r^{2} }[/tex].

Determine the acceleration of a raptor that reaches 25 m/s from rest in 6.5 s.
Answer:
3.8 m/s²
Explanation:
Average acceleration is the change in velocity over change in time.
a = Δv / Δt
a = (25 m/s − 0 m/s) / 6.5 s
a ≈ 3.8 m/s²
Final answer:
The raptor's acceleration is found using the formula a = Δv / t. By substituting the final velocity (25 m/s), initial velocity (0 m/s), and time (6.5 s), we determine the acceleration to be approximately 3.85 m/s².
Explanation:
The question asks us to determine the acceleration of a raptor that changes its velocity from rest to 25 m/s in 6.5 seconds.
To find the acceleration, we can use the formula:
a = Δv / t
Where:
a is the acceleration,Δv is the change in velocity, andt is the time.Since the raptor starts from rest, its initial velocity is 0 m/s, and its final velocity is given as 25 m/s. The time taken is 6.5 seconds. Substituting the values into the formula gives:
a = (25 m/s - 0 m/s) / 6.5 s = 25 m/s / 6.5 s = approximately 3.85 m/s²
Therefore, the raptor's acceleration is approximately 3.85 m/s².
A group of students were testing different insulators. They used three metal cans, one wrapped with bubble wrap, a second with a paper towel, and third unwrapped. Equal amounts of hot water were poured into each can and the temperature was noted at definite time intervals. The data is shown in the table.
From the data, they concluded that bubble wrap was the best insulating material. What is the weakness in the conclusion?
A) It is the better of two insulators only; it is not the best insulator.
B) The experiment should have been continued till the temperatures of the cans reached 0°C.
C) The experiment must be repeated at least three times before this conclusion can be drawn.
D) The data on the can without insulator is irrelevant and distracts from the main idea of the experiment.
Answer:
A)
Explanation:
The insulator is a material that creates a barrier for the heat transferred, maintaining the temperature of the system almost unaltered. To know what is the best insulator, the experiment needs to be done with an unwrapped can, so that is possible to know how much heat the can be lost, thus letter "d" is incorrect.
The temperature of the water would not achieve 0°C, but the ambient temperature, being in thermal equilibrium, so the letter "b" is also incorrect.
By the data given is already notice the insulator power, because the temperature decreases faster with the paper towel, thus it's not necessary to repeat the experiment only to know which one is better, so the letter "c" is incorrect.
But, it's not possible to affirm that the bubble wrap is the best insulating material, because exists a lot off insulating material that wasn't tested. Besides, the insulation depends on the thickness of the material.
Answer:
A
Explanation:
The term “best” means that there is nothing better. The student cannot conclude that bubble wrap is the best insulator after having tested only two insulating materials. It is the better of two insulators only; it is not the best insulator.
A feather is dropped onto the surface of the moon. How far will the feather have fallen if it reaches the surface in 9.00 seconds?

Explanation:
Using equation of motion;
S = ut + 1/2gt²
u = 0 ( initial velocity wasn't given)
t = 9s
g = 1.63m/s²
S = 0 + 0.5*(1.63)*(9²)
S= 66.015m
A certain steam turbine is designed to be used as both a power generator and a pump. When used as a generator, the turbine provides enough power to do 3* 10^10 J of work in 1 min. What is the power output of the turbine?
Answer:
5 x 10^8 W
Explanation:
Power = Energy ÷ time
given
Energy = 3 x 10^10J
time = 1 min = 60 s
Power = Energy ÷ time
= 3 x 10^10 ÷ 60
= 5 x 10^8 W
Final answer:
The power output of the steam turbine that does 3 × 10^10 joules of work in 1 minute is 500 megawatts.
Explanation:
The student asked about the power output of a steam turbine that does 3 × 10^10 joules of work in 1 minute. To determine the power output, we use the formula Power = Work / Time. The work done is 3 × 10^10 joules, and the time is 1 minute, which is 60 seconds. Therefore, the power output is:
Power = 3 × 10^10 J / 60 s = 5 × 10^8 watts or 500 megawatts.
This indicates that when functioning as a generator, this turbine can generate 500 megawatts of power.

I will mark the first RIGHT answer brainliest!
The work done on the block is B) 400 J
Explanation:
The work done when lifting an object is equal to the change in gravitational potential energy of the object:
[tex]W=mg \Delta h[/tex]
where
m is the mass of the object
g is the acceleration of gravity
[tex]\Delta h[/tex] is the change in height of the object
In this problem we have:
(mg) = 100 N is the weight of the block (product of mass and acceleration of gravity)
[tex]\Delta h = 6 m - 2 m = 4 m[/tex] is the change in heigth of the object
Substituting, we find the work done:
[tex]W=(100)(4)=400 J[/tex]

what happens when light travels from one medium to another with a different index of refraction at a zero degree angle of incidence?
Answer:
No Refraction takes places
Explanation:
When light travels from one medium to another at an angle of incidence 0 degree then no refraction takes place .
It is because according to Refraction law
[tex]n_{i}[/tex]sini = [tex]n_{r}[/tex]sinr
where [tex]n_{i} ,n_{r}[/tex] are the refractive index of medium of incidence and medium of refraction .
When i = 0 , left side of the equation becomes 0 and thus r (angle of refraction) must be zero. So No refraction takes place
Answer:
If the index of refraction of the medium is greater, the light slows down.
A feather is dropped onto the surface of the moon. How far will the feather have fallen if it reaches the surface in 9.00 seconds?
The distance covered by the feather is 65.5 m
Explanation:
The motion of the feather is a free-fall motion (affected only by the force of gravity), therefore it is a motion at constant acceleration, and so we can use the following suvat equation:
[tex]s=ut+\frac{1}{2}at^2[/tex]
where
s is the displacement
u is the initial velocity
t is the time
a is the acceleration
In this problem, we have
u = 0 is the initial velocity of the feather
t = 9.00 s is the time interval
[tex]a=g=1.62 m/s^2[/tex] is the acceleration of gravity on the Moon
And solving for s, we find the distance covered by the feather in its fall:
[tex]s=0+\frac{1}{2}(1.62)(9.00)^2=65.6 m[/tex]

A 2.3 kg block slides along a frictionless
horizontal with a speed of 5.3 m/s. After
sliding a distance of 8 m, the block makes
a smooth transition to a frictionless ramp
inclined at an angle of 43° to the horizontal.
The acceleration of gravity is 9.81 m/s.
5.3 m/s
2.3 kg
How far up the ramp does the block slide
before coming momentarily to rest?
Answer in units of m.
Answer:
The block slides 2.1 m up the ramp before coming momentarily to rest
Explanation:
Let the maximum height reached by the block be 'h' m.
Given:
Mass of the block is 2.3 kg.
Initial velocity of the block is, [tex]u=5.3\ m/s[/tex]
Since, the block comes momentarily to rest, the final velocity is zero.
Final velocity at the maximum height of the ramp is, [tex]v=0[/tex]
Acceleration due to gravity is, [tex]g=9.8\ m/s^2[/tex]
Angle of inclination is, [tex]\theta=43\°[/tex]
Now, since all the surfaces are frictionless, we can apply law of conservation of energy.
Therefore, as per conservation of energy,
Decrease in kinetic energy = Increase in potential energy
[tex]\frac{1}{2}m(u^2-v^2)=mgh\\\frac{1}{2}(5.3^2-0)=(9.8)h\\9.8h=\frac{28.09}{2}\\h=\frac{28.09}{2\times 9.8}=1.43\ m[/tex]
The maximum height reached by the block is 1.43 m. Now, the distance traveled along the ramp is the hypotenuse.
The hypotenuse length of the block along the ramp is given as:
[tex]L=\frac{h}{\sin \theta}\\\\L=\frac{1.43}{\sin 43\°}\\L=2.1\ m[/tex]
Therefore, the block slides 2.1 m up the ramp before coming momentarily to rest.

Newton third law states that what objects and what forces on each other
"When an object A exerts a force (called action) on an object B, then object B exerts an equal and opposite force (called reaction) on object A"
Explanation:
Newton's third law of motion states that:
"When an object A exerts a force (called action) on an object B, then object B exerts an equal and opposite force (called reaction) on object A"
it is important to note that the pair of forces (action and reaction) do not act on the same object, but on different objects: therefore, they never appear in the same free-body diagram of an object.
There are several examples where Newton's third law is applied in daily life. For instance:
A book at rest on the table: the book exerts a downward force on the table, and the table exerts an upward force (normal reaction) on the bookIf you push against the wall, you exert a force (action) on the wall, and the wall exerts a force (reaction) back on you, of equal magnitudeA satellite in orbit around the Earth: the gravitational force exerted by the Earth on the satellite is equal to the gravitational force exerted by the satellite on the EarthLearn more about Newton's third law:

Answer is " A convex line runs downward from 0 seconds some positive number of meters to some positive number of seconds 0 meters. "
Explanation:
The figure shows Velocity vs Time Graph.
At t1=0, u=10m/s
At t2=5, v=2m/s
Let's calculated the acceleration
[tex]a=\frac{v-u}{t2-t1}[/tex]
[tex]a=\frac{2-10}{5-0}[/tex]
[tex]a=\frac{-8}{5}[/tex]
The equation of distance is given by
[tex]d=ut+\frac{a}{2} t^{2}[/tex]
[tex]d=(10)t+\frac{\frac{-8}{5}}{2} t^{2}[/tex]
[tex]d=10t+\frac{-8}{10} t^{2}[/tex]

1. What is the average velocity of a car that moved 40 km East and 80 km West in 2 hours?
The average velocity is 20 km/h west
Explanation:
The velocity of an object is given by:
[tex]velocity = \frac{d}{t}[/tex]
where
d is the displacement
t is the time elapsed
The displacement of an object is a vector connecting the initial position and the final position of motion.
In this problem, the car moved
40 km East
80 km West
Therefore, the displacement is given by (taking West as positive direction)
[tex]d=80 km - 40 km = 40 km[/tex] West
The time elapsed is
t = 2 h
Therefore, the average velocity is
[tex]v=\frac{40 km}{2h}=20 km/h[/tex] in the West direction.

brainly.com/question/5063905
#LearnwithBrainly
Final answer:
The average velocity of the car is -20 km/h toward the West, calculated by dividing the net displacement (-40 km) by the total time (2 hours).
Explanation:
To find the average velocity of the car, we need to consider the total displacement and the total time. Displacement is the change in position of the car, and since velocity is a vector quantity, it also includes direction. The car first moves 40 km East and then 80 km West, resulting in a total displacement of 40 km East - 80 km West = -40 km (where negative indicates the direction West).
The total time taken is 2 hours. Therefore, the average velocity v is calculated as:
v = Total Displacement / Total Time = -40 km / 2 hours = -20 km/h
The negative sign indicates that the average velocity is directed toward the West.
The density of a material is calculated by:
Answer:

Arthur reads an article describing an experiment to test the effects of caffeine on the reaction time of humans—how long it took them to respond to a particular signal. In the experiment, the subjects' reaction times were measured, then they were divided into three groups. One group was given a high dose of caffeine. The second group was given a medium dose of caffeine. The third group was given a sugar pill that had no caffeine. After waiting 45 min for the caffeine to take effect, the reaction times were measured again.
In the experiment Arthur read about, what was the dependent variable?
A.
the amount of caffeine given to each person
B.
the type of signal each person responded to
C.
the amount of time the caffeine was given to take effect
D.
the change in reaction times for each person
Answer:
the change in reaction times for each person
Explanation:
The dependent variable in Arthur's article on the effects of caffeine on human reaction time is the change in reaction times for each person after consuming caffeine or a placebo.
Explanation:In the described experiment, the dependent variable is the change in the subjects' reaction times after they have been administered varying amounts of caffeine or a placebo. This is because the dependent variable is the factor that the researchers are measuring to see if it changes in response to the manipulation of the independent variable (in this case, the amount of caffeine given to each person). The different doses of caffeine or the placebo (sugar pill) represents the independent variables, because they are what the researchers are manipulating to see if there is an effect on the dependent variable.
Therefore, the correct answer to the question 'In the experiment Arthur read about, what was the dependent variable?' is D. the change in reaction times for each person.

If all of the forces acting on an object are balanced, then:
Check all that apply.
I
A. the direction the object is moving in will not change.
B. the acceleration of the object will be 0 m/s2
I
c. the object will not be in motion.
D. the velocity of the object will be 0 m/s.
A. the direction the object is moving in will not change.
B. the acceleration of the object will be 0 m/s2
Explanation:
We can answer this problem by using Newton's second law of motion:
[tex]\sum F = ma[/tex]
where
[tex]\sum F[/tex] is the net force acting on an object
m is the mass of the object
a is its acceleration
In this problem, all the forces acting on the object are balanced, therefore the net force is zero:
[tex]\sum F=0[/tex]
which means that also the acceleration is zero:
[tex]a=0[/tex]
Acceleration is equal to the rate of change of velocity: therefore, zero acceleration means that the velocity of the object does not change. We can now analyze the given statements:
A. the direction the object is moving in will not change. --> TRUE, because the velocity is not changing.
B. the acceleration of the object will be 0 m/s2 --> TRUE, as we stated above
c. the object will not be in motion. --> FALSE: we just know that its velocity is constant, but it can be different from zero
D. the velocity of the object will be 0 m/s. --> FALSE, for the same reason stated in C

Final answer:
When all of the forces on an object are balanced, the object will not change its direction of motion, its acceleration will be 0 m/s^2, and its velocity will be 0 m/s.
Explanation:
When all of the forces acting on an object are balanced, several things occur:
The direction the object is moving in will not change. This is because there is no net force acting on the object to change its motion.The acceleration of the object will be 0 m/s². This is because acceleration is directly proportional to the net force acting on an object, and if the forces are balanced, there is no net force and therefore no acceleration.The velocity of the object will be 0 m/s. Velocity is the rate at which an object changes its position, and if the forces are balanced, there is no change in position and therefore the velocity is 0 m/s.Type O negative blood is considered the universal red blood cell donor because it _____.

If a crane worker lifts a crate with a mass of 200 kg from the ground to a
shipping container that is 45 meters off the ground, by how much has the
worker increased the gravitational potential energy of the crate? (Recall that g
= 9.8 m/s2)
A. 88,200 J
B. 31,900 J
C. 63,500 u
D. 48,100 J
Answer:
A. 88,200 J
Explanation:
Given data,
The mass of the crate, m = 200 kg
The height of the shipping container, h = 45 m
The gravitational of a body is possessed by the body due to the virtue of its position.
The formula for gravitational potential energy is,
P.E = mgh joules
Substituting the values
P.E = 200 x 9.8 x 45
= 88,200 J
Hence, the gravitational potential energy of the crate is, P.E = 88,200 J
An airplane weighing 11,000 N climbs to a
height of 1.6 km in 9.8 min. Calculate the
accomplished power in horsepower.
The power in horsepower is 40.1 hp
Explanation:
We start by calculating the work done by the airplane during the climb, which is equal to its change in gravitational potential energy:
[tex]W=(mg)\Delta h[/tex]
where
mg = 11,000 N is the weight of the airplane
[tex]\Delta h = 1.6 km = 1600 m[/tex] is the change in height
Substituting,
[tex]W=(11,000)(1600)=17.6\cdot 10^6 J[/tex]
Now we can calculate the power delivered, which is given by
[tex]P=\frac{W}{t}[/tex]
where
[tex]W=17.6\cdot 10^6 J[/tex] is the work done
[tex]t=9.8 min \cdot 60 = 588 s[/tex] is the time taken
Substituting,
[tex]P=\frac{17.6\cdot 10^6 J}{588}=2.99\cdot 10^4 W[/tex]
Finally, we can convert the power into horsepower (hp), keeping in mind that
[tex]1 hp = 746 W[/tex]
Therefore,
[tex]P=\frac{2.99\cdot 10^4}{746}=40.1 hp[/tex]

#LearnwithBrainly
Final answer:
The power accomplished by an airplane weighing 11,000 N climbing to a height of 1.6 km in 9.8 min is calculated by determining the change in gravitational potential energy and then converting that work into power over the time taken. The result is approximately 40.13 horsepower.
Explanation:
To calculate the power accomplished, we can use the work-energy principle where the work done by the airplane engines to climb to the height is equal to the change in gravitational potential energy. The gravitational potential energy (GPE) change is calculated as the weight of the airplane times the height it reaches. The formula for GPE is:
GPE = weight × height
For the airplane problem, we have:
GPE = 11,000 N × 1.6 km = 11,000 N × 1600 m = 17,600,000 J (joules)
Next, we convert 9.8 minutes to seconds to find the power in watts. Power is work (or GPE here) divided by time:
Time = 9.8 minutes × 60 seconds/minute = 588 seconds
Power in watts = GPE / Time
Power in watts = 17,600,000 J / 588 s ≈ 29,932 W (watts)
To convert power to horsepower, we use the conversion factor 1 horsepower ≈ 746 watts:
Power in horsepower = Power in watts / 746
Power in horsepower ≈ 29,932 W / 746 ≈ 40.13 hp
Therefore, the accomplished power in horsepower while the airplane climbs to a height of 1.6 km in 9.8 min is approximately 40.13 hp.
