What’s the force of a pitching machine on a baseball? Baseballs pitched by a machine have a horizontal velocity of 30 meters/second. The machine accelerates the baseball from 0 meters/second to 30 meters/second in 0.5 seconds. If a baseball has a mass of 0.15 kilograms, the force the machine exerts is newtons. Use F = ma, where .

Answers

Answer 1

The acceleration of the baseball is:
[tex]a= \frac{v_f-v_i}{\Delta t} [/tex]
where [tex]v_f[/tex] and [tex]v_i[/tex] are the final and initial speed of the ball, and [tex]\Delta t[/tex] is the time interval in which the force acted.

Replacing the numbers, we get
[tex]a= \frac{30 m/s-0m/s}{0.5 s}=60 m/s^2 [/tex]
And at this point, we can use Newton's second law F=ma to find the value of the force of the pitching machine:
[tex]F=ma=(0.15 kg)(60 m/s^2)=9 N[/tex]

Answer 2

Answer:

So F=ma

The acceleration of the baseball is:

If red and yellow paint are mixed together, which color of light will be reflected?

A. Orange
B. Red
C. White
D. Black

Answers

the answer is A. it will make orange

The correct answer is: Option (A) Orange

Explanation:
When two or more colors mixed together, the color of light that is reflected back represents the equivalent color for the different colors you mixed. Let's take white color as an example. If you mixed up all the color of the light spectrum, you will get the white color (which is reflected). Likewise, when red and yellow paints are mixed together, it is the orange color that is reflected. Hence the correct option is (A) Orange.

The closeness of measured values to an accepted value is the BLANK of the data ?

Answers

Answer: accuracy

Justification:

Any measure of a physical data is subject to errors. The errors can be of different kind.

The closer is a measure to the real or accepted value the more accurate the measure is.

For example, if you measure the length of a sheet of paper letter size and you know that the accepted value is 11 inches, then you can tell how accurate your measure is comparing with 11 inches.

Many times the measure is affected by the accuracy of the instrument used (the divisions), but it is also subject to human errors, and may be errors due to the method of measuring.

I need help with 2 questions . Please help c:

1 . According to the nebular theory, the solar system formed from ?

accretion of protoplanets.
a large, thin cloud of dust and gas.
colliding planetesimals.
all of the above

2. Which of the following statements explains why the terrestrial planets are small and rocky instead of large and less dense like the gas giants?

The inner planets were exposed to much higher temperatures.
Ice-forming compounds vaporize at high temperatures.
Rock-forming materials can condense at high temperatures.
all of the above

Answers

a) According to the nebular theory, the Solar System formed from a huge gaseous nebula which at a certain point was perturbated. Atoms and molecules started colliding, forming planetesimals (a sort of big rocks). The planetesimals were attracted to each other by gravity, forming bigger warm almost spherical objects called protoplanets, which at the end cooled down forming planets.
Therefore the correct answer is "all of the above".

b) The planets closer to the Sun were (and still are) subject to higher temperatures, due to their close distance to the Sun. In these conditions, rocky materials undergo condensation, while iced gaseous materials undergo vaporization. In the outer parts of the Solar System temperatures are too low to allow these transformations.
The correct answer is again "all of the above".

B. The air pressure increases.
C. The air pressure stays the same.
D. More information is needed.,

Answers

A) pressure = Force/ Area. Pressure = 1.5/0.5 = 3. B) Option A. The air pressure decreases. Since atmospheric pressure decreases with increasing altitude, as the plane soars higher and higher the pressure on the outside decreases since there are fewer air molecules -- the total weight of the air above a unit area becomes increasingly small. As we move higher up earth's surface, there are fewer air molecules than at lower levels; this explains why pressure decreases with increasing altitude.

as an object falls freely toward earth, the object's momentum is

1. decreses
2. inceases
3. remains the same,

Answers

The momentum of an object is the result of the mass of that object and the velocity by which it travels. So, since as an object falls towards the earth it's velocity increases, it's momentum would also increase at least until the object reaches its terminal velocity.

The object's momentum remains the same as it descends freely toward the earth.

So, option 3. is correct.

Define momentum.

Momentum is a measurable quantity that exists because an object is moving and has mass. The mass multiplied by the velocity equals momentum. If an item is stationary, its velocity is zero, and it has no momentum.

When an object descends toward Earth, it accelerates due to gravity, accumulating speed and momentum until the upward force of air resistance equals the downward force due to the object's weight under gravity, a point known as terminal velocity.

The law of conservation of momentum asserts that the overall momentum of objects that interact does not change in the absence of external forces such as friction.

So,

The object's momentum 3. remains the same as it descends freely toward the earth.

True or false, The golf club is swung in a northernly direction, and that is the direction the ball travels

Answers

Yes the answer is trye

Final answer:

The statement is false since merely swinging the golf club in a northern direction does not ensure that the ball will travel in that direction due to external influences like wind and gravity, much like an airplane can be blown off course.

Explanation:

The statement "The golf club is swung in a northernly direction, and that is the direction the ball travels" is false. In physics, particularly when discussing vectors and motions, the direction that an object is initially moved by a force (like a golf club hitting a ball) does not necessarily dictate that the object will continue to move in that initial direction. Various other forces and factors can influence the trajectory. For example, merely swinging the club in a northern direction does not account for factors such as wind, slope of the ground, spin of the ball, and gravity, all of which can alter the path of the golf ball.

Consider the analogy provided using an airplane's motion. An airplane heading north can be moved off that northward path by the wind, causing it to drift westward. Similarly, swinging the golf club in one direction does not guarantee the ball will follow that path precisely. Additionally, according to physics, when a magnet breaks, all pieces will indeed still have north and south poles, indicating that the physical direction is not the only factor determining the outcome—in both magnetism and ball trajectory.

An object has a kinetic energy of 275 j and a momentum of magnitude 25.0 kg · m/s. find the (a) speed and (b) mass of the object.

Answers

Kinetic energy = momentum^2 / 2 x mass
Mass = (momentum^2/ Kinetic energy) / 2

Mass = (25^2 / 275) / 2
Mass = 1.136 kg.

momentum = mass x velocity

velocity = mass / momentum
velocity = 1.136 / 25
velocity = 0.04544 m/s

Answer: The correct answers are 482.4 m/s and 21.96 kg.

Explanation:

The expression for the kinetic energy in terms of momentum of an object is as follows;

[tex]KE=\frac{p^{2} }{2m}[/tex]

Here, KE is the kinetic energy, p is the momentum and m is the mass of the object.

It is given in the problem that an object has a kinetic energy of 275 j and a momentum of magnitude 25.0 kg · m/s.

Calculate the mass of the object.

[tex]KE=\frac{p^{2} }{2m}[/tex]

Put p=25.0 kg · m/s and KE= 275 J.

[tex]m=\frac{25^{2} }{2(275)}[/tex]

[tex]m=1.14 kg[/tex]

Calculate the speed of the object.

[tex]KE=\frac{1}{2} mv^{2}[/tex]

Put m= 1.14 kg and KE= 275 J.

[tex]v=\sqrt{\frac{2(275)}{1.14} }[/tex]

v=21.96 m/s

Therefore, the speed of the object is 21.96 m/s and the mass of the object is 1.14 kg.

How much gravitational potential energy does the block have
when it gets to the top of the ramp ?

(weight) x (height) = (15 N) x (0.2 m) = 3 Joules .

If there were no friction, you would only need to do 3 Joules of work
to lift the block from the bottom to the top.

But the question says you actually have to do 4 Joules of work
to get the job done.

Friction stole one of your Joules along the way.

Choice-4 is not the correct one.
Choice-1 is the correct one.

===========================

Notice that the mass of the block is NOT 15 kg , and you
don't have to worry about gravity to answer this question.

The formula for potential energy is (m)·(g)·(h) .
But (m·g) is just the WEIGHT, and the formula
is actually (weight)·(height).
The question GIVES us the weight of the block . . . 15 N .
So the potential energy at the top is just (15N)·(0.2m) = 3 Joules.

1. Show how the alternative definition of power, found in your book, can be derived by substituting the definitions of work and speed into the standard definition of power, P = W / delta t.

2. A real spring does not oscillate forever. Instead, it eventually comes to a stop. Does this violate the Law of Conservation of Energy? Explain why or why not.

Answers

1) Star from the definition of power:

P = work/ time = W / Δt

We know that work is given by force times displacement:
W = F · Δd
Substituting in our formula:
P = F · Δd / Δt

But we know by definition that Δd / Δt = velocity, therefore we can write:
P = F · v
which is the alternative formula saying that Power is equal to Force times Velocity

2) No, it is not a violation of the Law of conservation of energy because as the spring slows down, the kinetic energy is transformed into potential energy and their sum stays constant.

=88.46%

efficiency is (output/input)×100
if u get confused which way input and output should go, remember the smaller value is always output and it's above in the fraction, then only it's possible to get a efficiency lower than 100.

Answer:

The machine with work input of 104,000Joules and work output of 92,000 has the greater efficiency

Explanation:

Efficiency of a machine is the ratio of work done by a machine(work output) to work put in the machine (work input).

Mathematically,

Efficiency = Work output/Work Input ×100

For the machine with work output of 89,000Joules and work input of 102,000Joules, its efficiency will be;

Efficiency = 89,000/102,000×100

Efficiency = 87.5%

Similarly for the other machine with work output of 92,000Joules and work input of 104,000Joules, its efficiency will be;

Efficiency = 92,000/104,000×100

Efficiency = 88.5%

Comparing the efficiency of both machines, the machine with efficiency of 88.5% has greater efficiency.

Without making all the calculations, a fraction is bigger than another when the denominator is smaller. Therefore you need to find the smallest wavelength (λ) which is 450nm.

You could also be helped by colors: in order of decreasing energy, you have blue - green - yellow - red.

In any case, the correct answer is a).

Final answer:

The greatest energy transition from a higher energy level to a lower one is represented by the emission of a blue photon of 450 nm.

Explanation:

The greatest energy transition from a higher energy level to a lower one is represented by the emission of a blue photon of 450 nm. This is because the energy of a photon is inversely proportional to its wavelength. As the wavelength decreases, the energy increases. Since blue light has a shorter wavelength than red, green, and yellow light, it has the highest energy.

A Ferris wheel at a carnival has a diameter of 62 feet. Suppose it turns at a rate of 70 revolutions per hour.
(a) Find the angular speed of the wheel in radians per hour.
(b) Find the linear speed of a passenger in feet per minute.

Do not round any intermediate computations, and round your answer to the nearest whole number.,

Answers

(a) Angular Speed is 140π radians per hour.

(b) The linear speed of a passenger on the Ferris wheel is approximately 3.249 feet per minute.

To find the angular speed of the Ferris wheel in radians per hour, you can use the following formula:

Angular Speed (ω) = (2π * Number of Revolutions) / Time

(a) Angular Speed in Radians per Hour:

Number of Revolutions = 70 revolutions

Time = 1 hour

ω = (2π * 70) / 1

ω = 140π radians per hour

Now, to find the linear speed of a passenger in feet per minute, you need to consider the circumference of the Ferris wheel.

(b) Circumference of the Ferris Wheel:

The diameter of the Ferris wheel is given as 62 feet, so the radius (r) is half of that, which is 31 feet. The circumference (C) of the wheel is given by:

C = 2πr

C = 2π * 31 feet

C ≈ 194.94 feet

Now, to find the linear speed (v) in feet per minute, you can use the formula:

Linear Speed (v) = (Circumference / Time)

Time in this case is 1 hour, which is equivalent to 60 minutes:

v = 194.94 feet / 60 minutes

v ≈ 3.249 feet per minute

Hence, the linear speed of a passenger on the Ferris wheel is approximately 3.249 feet per minute.

Valence electrons are the electrons of the outer shells of atoms not bound with other atoms (for example through covalent bounds). These electrons are "free to escape" as soon as an electric field with enough intensity is applied to the material, and therefore these electrons will be free to move in the material producing an electric current.

James rode his bike 0.65 hours and traveled 8.45 km. What was his speed?

Answers

Speed = (distance covered) / (time to cover the distance)

= ( 8.45 km) / (0.65 hr)

= (8.45 / 0.65) km/hr

= 13 km/hr

Final answer:

James's average speed was calculated by dividing the distance he traveled, 8.45 km, by the time it took, 0.65 hours, resulting in an average speed of 13 km/h.

Explanation:

To find James's speed, you need to divide the total distance he traveled by the total time it took him. In this case, the distance traveled is 8.45 km and the time is 0.65 hours. Use the formula speed = distance/time to calculate the speed.

The calculation would be:

Convert time to the same unit as speed (hours to minutes or kilometers per hour). Here, the time is already in hours.Divide the distance by the time: 8.45 km ÷ 0.65 hours = 13 km/h.

So, James's average speed while riding his bike was 13 kilometers per hour (km/h).

The typical speed is the all out distance went by the item in a specific time stretch. The typical speed is a scalar amount. It is addressed by the greatness and doesn't have heading.
