Answer:
50 m/s²
Explanation:
From Newton's second law:
F = ma
25 N = (0.50 kg) a
a = 50 m/s²
The acceleration of a softball with a mass of 0.50kg and a force applied of 25N can be found by using Newton's second law of motion (F=ma). Upon rearranging the equation to solve for acceleration (a) and substituting the given values, we find that the acceleration is 50 m/s².
Explanation:To find the acceleration of the softball, we use Newton's Second Law of Motion, which states that the acceleration of an object is dependent upon the net force acting upon the object and the mass of the object, represented by the formula F = ma, where F is force, m is mass, and a is acceleration.
In this case, the force (F) applied on the softball is 25N and the mass (m) of the softball is 0.50kg. Rearranging the equation of Newton's second law to solve for acceleration (a), we get a = F/m.
Substituting the given values, we have a = 25N / 0.50kg. Solving the equation yields an acceleration (a) of 50 m/s².

What must you do to calculate a meaningful value of distance from the following equation?
d= (0.90km) + (12.5km)/h x (31.5s)
-Convert the kilometers to meters.
-Convert the kilometers to miles.
-Drop the symbols for the units.
-Convert all the times to either hours or seconds.
Answer:
Convert all the times to either hours or seconds
Explanation:
One time unit is in hours, and the other is in seconds. In order to do the math, the units need to be the same. So you either need to convert hours to seconds, or seconds to hours.
Answer:
-Convert all the times to either hours or seconds.
Explanation:
Given,
[tex]d= (0.90km) + (12.5km/h) \times (31.5s)[/tex]
While doing a mathematical calculation all the units should be same otherwise the result will not be correct. Here two units of time i.e. second and hour are being used. We will convert the second to hour by dividing it by 3600 as there are 3600 seconds in one hour. The distance will be,
[tex]d= (0.90km) + (12.5km/h) \times (\frac{31.5}{3600}h)[/tex]
[tex]d= 0.90 + 12.5 \times \frac{31.5}{3600}[/tex]
[tex]d= 0.90 + \frac{393.75}{3600}[/tex]
[tex]d= 0.90 + 0.109[/tex]
[tex]d= 1.009 km[/tex]
2. Calculate the average magnitude of the force of gravity on the planet Neptune (mass of 1.02*10^ 26 kg) due to the Sun (mass of 1.99*10^ 30 kg) , assuming an average orbital distance of 4.50*10^ 12 m.
Answer:
The answer to your question is: F = 6.69 x 10²⁰ N
Explanation:
To solve this problem we need to use the Newton's law of universal gravitation.
F = G(m1m2)/r²
where
F = ?
G = 6.674×10−11 N · (m/kg)2 is the gravitational constant
m1 = Neptune mass = 1.02 x 10²⁶ kg
m2 = Sun mass = 1.99 x 10³⁰ kg
r orbital distance among the planets = 4.50 x 10¹² m
Substitution
F = 6.674×10−11 N · (m/kg) x 1.02 x 10²⁶ kg x 1.99 x 10³⁰ kg / (4.50 x 10¹² m)²
F = 1.355 x 10⁴⁶ / 2.025 x 10²⁵
F = 6.69 x 10²⁰ N
The average magnitude of the force of gravity on Neptune due to the Sun is approximately [tex]\( 6.714 \times 10^{20} \, \text{Newtons} \).[/tex]
The average magnitude of the force of gravity F on the planet Neptune due to the Sun can be calculated using Newton's law of universal gravitation, which states that the force between two masses is proportional to the product of their masses and inversely proportional to the square of the distance between their centers. The formula is given by:
[tex]\[ F = G \frac{m_1 m_2}{r^2} \][/tex]
Plugging in the values, we get:
[tex]\[ F = (6.674 \times 10^{-11} \, \text{Nm}^2/\text{kg}^2) \frac{(1.99 \times 10^{30} \, \text{kg}) (1.02 \times 10^{26} \, \text{kg})}{(4.50 \times 10^{12} \, \text{m})^2} \] \[ F = (6.674 \times 10^{-11} \, \text{Nm}^2/\text{kg}^2) \frac{2.03 \times 10^{56} \, \text{kg}^2}{2.025 \times 10^{25} \, \text{m}^2} \] \[ F = 6.697 \times 10^{-11} \times 1.003 \times 10^{31} \, \text{N} \]\\ \[ F \approx 6.714 \times 10^{20} \, \text{N} \][/tex]

1. Answer true or false to the following:
A ball rolling on a flat table has a horizontal but no vertical
component of motion.
A rock falling straight downward with no wind blowing has no
horizontal component of motion.
A baseball hit into the air toward right field has vertical but no
horizontal component of motion.
A basketball bounced straight up and down has vertical but no
horizontal component of motion.
Ball -- true
Rock -- true
Baseball -- False
Basketball -- true
All the statements are true except the third statement related to baseball hit into the air toward right field has vertical but no horizontal component of motion.
True- A ball rolling on a flat table has a horizontal but no vertical component of motion.
True- A rock falling straight downward with no wind blowing has no horizontal component of motion.
False- A baseball hit into the air toward right field has vertical but no horizontal component of motion.
True- A basketball bounced straight up and down has vertical but no horizontal component of motion.
Answer: Option true 1, 2, 4, and false 3
Explanation:
For the first statement of ball rolling on a flat table, as the table was flat, the acceleration due to gravity may not be acting on the ball kept on the table. When external push is given on the ball kept on the flat table, the ball will be moving along the direction of the push and not perpendicular to the direction of push.
So, the statement 1 is true. Similarly, the motion of rock as well as basketball in a straight up and down direction exhibit only the vertical component as both of them will be moving due to acceleration due to gravity.
So, the second and last statement is also true. But in case of baseball hitting the air toward right field means the ball is made to hit at a particular angle. So as the baseball will follow a path of parabola it will have only horizontal component of motion and not vertical component of motion. So the third statement is false.

A car is traveling at an average speed of 70
m/s. How many km would the car travel in
6.5 hrs?
A car is traveling at an average speed of 70 m/s, the car would travel approximately 1638 kilometers in 6.5 hours at an average speed of 70 m/s.
To calculate the distance traveled by the car, we can use the formula:
[tex]\[ \text{Distance} = \text{Speed} \times \text{Time} \][/tex]
Given:
Average speed of the car: [tex]\(70 \, \text{m/s}\)[/tex]
Time: [tex]\(6.5 \, \text{hrs}\)[/tex]
First, let's convert the time from hours to seconds, as the speed is given in meters per second:
[tex]\[ \text{Time in seconds} = \text{Time in hours} \times 3600 \, \text{s/hr} \][/tex]
[tex]\[ \text{Time in seconds} = 6.5 \times 3600 \, \text{s} \][/tex]
Now we can use the formula to calculate the distance traveled:
[tex]\[ \text{Distance} = 70 \times \text{Time in seconds} \][/tex]
Finally, let's convert the distance from meters to kilometers:
[tex]\[ \text{Distance in kilometers} = \frac{\text{Distance in meters}}{1000} \][/tex]
Substitute the calculated values:
[tex]\[ \text{Distance in kilometers} = \frac{70 \times 6.5 \times 3600}{1000} \][/tex]
[tex]\[ \text{Distance in kilometers} \approx 1638 \, \text{km} \][/tex]
Thus, the car would travel approximately 1638 kilometers in 6.5 hours at an average speed of 70 m/s.

A. pulls back on the Earth
B. can only pull on smaller objects such as asteroids but has no effect on the Earth
C. doesn´t affect anything
D. pushes the moon away from the Earth
Answer:
A. pulls back on the Earth, which is the main cause of the rise and fall of the ocean tides on Earth.
The moon’s gravity pulls back on the Earth. Therefore, option (A) is correct.
What is the moon's gravity?The Moon's gravity can be described as the acceleration due to gravity on the surface of the Moon. The value of g on the Moon can be calculated by considering the mass of the Moon and earth.
The mass of the Moon is equal to 7.342 x 10²² kg which is 1.2% of the mass of the earth and the radius of the Moon = 1.74 x 10⁶ m
Since the formula to calculate the value of g = GM/r2
The value of the g for the Moon is equal to 1.652 m/s² which is 16.7 % of the gravity of the earth.
The moon's gravity on the Earth is the reason for the rise and fall of ocean tides. The moon's gravitational pull arises two bulges of water on the oceans of the earth in which one where ocean waters face the moon and the pull is strongest and another where ocean waters face away from the moon and the pull is weakest.
Therefore, the gravity of the moon pulling back on the Earth is the correct option.

one car moving in a straight line covers one third distance in 20km/h and rest in 60km/h . find the average speed
Answer:
36 km/h
Explanation:
If d is the total distance, then the time spent driving at 20 km/h is:
t₁ = (d/3) / 20
t₁ = d / 60
And the time spent driving at 60 km/h is:
t₂ = (2d/3) / 60
t₂ = d / 90
So the total time is:
t = t₁ + t₂
t = d/60 + d/90
t = d/36
The average speed is the total distance divided by total time:
s = d / t
s = d / (d/36)
s = 36
The average speed is 36 km/h.
Two 6.0 kg masses are separated by a distance of 4.0 m. What is the magnitude of the gravitational force between the two masses?
Answer: [tex]1.50075*10^{-10}\ N[/tex]
Explanation:
For this exercise we need to use the Gravitational Force Formula. This is:
[tex]F_g=G(\frac{m_1*m_2}{r^2})[/tex]
Where [tex]F_g[/tex] is the gravitational force between two objects, [tex]G[/tex] is the gravitational constant ([tex]G=6.67*10^{-11}\ \frac{Nm^2}{kg^2}[/tex]) and [tex]r[/tex] is the distance between the objects.
We know that:
[tex]m_1=6.0\ kg\\\\m_2=6.0\ kg\\\\r=4.0\ m[/tex]
Therefore, in order to calculate the magnitude of the gravitational force between the two masses, we must substitute these values into the formula.
Then we get:
[tex]F_g=(G=6.67*10^{-11}\ \frac{Nm^2}{kg^2})(\frac{(6.0\ kg)(6.0\ kg)}{(4.0\ m)^2})\\\\F_g=1.50075*10^{-10}\ N[/tex]
what would happen when an inflated balloon is place in an ice bath and the atmosphere pressure has not changed?
The inflated balloon shrinks when it is placed in an ice bath with no change in atmospheric pressure.
Explanation:
When the inflated balloon is subjected to an ice bath, it shrinks. This is due to the fact that smaller volume gets occupied by the air/gas inside the balloon as the temperature decreases. Hence, causes the balloon walls to collapse.
An ice bath also lowers the overall air temperature of the balloon inside. As the temperature decreases, the air molecules move more slowly and with lower energy. Because of the particle's lower energy, their collisions with the walls are not enough to keep the inflated balloon.

the brakes, how far will she have moved before
she begins to slow down?
Answer in units of m.
Answer:
13.5 m
Explanation:
First, convert km/h to m/s:
64 km/h × (1000 m / km) × (1 h / 3600 s) = 17.8 m/s
Distance = rate × time
d = 17.8 m/s × 0.761 s

Which type of force will an object move towards?
A) weakest
B) strongest
C) net
D) balanced
Answer:
i think it's weakest
EDIT: It's net. I answered weakest but it was wrong and the correct answer was net. oops
Explanation:
if a strong force is acting on something it will push it away, meaning the object would go towards the weaker force
An object will move towards the strongest force acting on it. Option B is correct.
In physics, the net force on an object determines its motion. The net force is the vector sum of all the individual forces acting on the object. When there is a stronger force in a particular direction compared to the other forces, the object will accelerate in that direction.
Newton's second law of motion states that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. Mathematically, this can be expressed as
F=ma, where
F is the net force,
m is the mass of the object, and
a is the acceleration.
When multiple forces act on an object, they can either be in the same direction, adding up to create a stronger net force and causing acceleration, or they can be in opposite directions, balancing each other out and resulting in no net force and no acceleration (balanced forces).
In summary, an object will move towards the direction of the strongest force acting on it because that force will result in the greatest acceleration, according to Newton's second law of motion.

Which factors are used to calculate the kinetic energy of an object? Check all that apply. gravity velocity volume mass height
Quantities that determine the kinetic energy of a body are its mass and velocity
Answer: mass and velocity
Explanation:
The kinetic energy of a body is the energy possessed by an object by virtue of its motion. It is given by the equation
[tex]k= \frac{1}{2}mv^2[/tex]
Where m represents mass of the body and v represents its velocity.
Two bodies of equal velocity but different mass the heavier body will have greater kinetic energy. When an object is at rest its velocity is equal to zero. Thus its kinetic energy will be zero. Hence it can be concluded that only moving bodies have kinetic energy.
Stationary objects placed at a height possess potential energy which is the energy by virtue of their position or configuration. The total mechanical energy of a system is the sum of potential and kinetic energy.

The statement associating a low BMI with a healthy body weight is false. A healthy body weight, as indicated by BMI, falls within the 18-24.9 range. However, BMI is an imperfect measure and can be misleading due to its disregard for muscle mass, fat distribution, and bone density.
Explanation:The statement that a healthy body weight is associated with a low body mass index (BMI) is False. A healthy body weight, as indicated by BMI, falls within a range. A BMI ranging from 18-24.9 is considered normal weight, 25-29.9 is considered overweight, and a BMI greater than 30 is considered obese. However, BMI has its limitations. It does not account for muscle mass, fat distribution, or bone density, which can lead to inaccuracies in determining actual health status. A muscular person may have a high BMI but low body fat, while an individual with less muscle mass might have a lower BMI but higher body fat percentage.
6. What is the acceleration of an object that accelerated steadily from rest, traveling 10 m in 10 s?
Answer:
0.2 m/s²
Explanation:
Given:
x₀ = 0 m
x = 10 m
v₀ = 0 m/s
t = 10 s

The tallest sequoia sempervirens tree in California’s redwood national parks is 111 m tall. Suppose an object is thrown downward from the top of that tree with a certain initial velocity. If the object reaches the ground in 3.80 s, what is the objects initial velocity?
The object's initial velocity is equal to [tex]-10.59\frac{m}{s}[/tex]
Why?
From the statement we know the height of the tree and the time it takes to reach the ground, so, if we need to calculate its initial velocity, we can use the following formula:
[tex]y=y_o-v_{o}*t-\frac{1}{2}g*t^{2}[/tex]
Where,
y, is the final height (0 meters in this case)
yo, is the initial height (111 meters in this case)
t, is the time elapsed (3.8 seconds in this case)
vo, is the initial speed.
g, is the acceleration due to gravity (-9.81 m/s2)
Now, let's set the origin at the top of the tree, so, rewriting the formula, we have:
[tex]y=y_o+v_{o}*t+\frac{1}{2}g*t^{2}[/tex]
So, isolating the initial velocity, we have:
[tex]y=y_o+v_{o}*t+\frac{1}{2}g*t^{2}[/tex]
[tex]y=y_o+v_{o}*t+\frac{1}{2}g*t^{2}\\\\v_{o}*t=y-y_o-\frac{1}{2}g*t^{2}\\\\v_{o}=\frac{y-y_o-\frac{1}{2}g*t^{2}}{t}[/tex]
Finally, substituting and calculating, we have:
[tex]v_{o}=\frac{-111m-0-\frac{1}{2}(-9.8\frac{m}{s^{2}}) *(3.8s)^{2})}{3.8s}\\\\v_{o}=\frac{-111m-\frac{1}{2}(-9.8\frac{m}{s^{2}})*(14.44s^{2})}{3.8s}\\\\v_{o}=\frac{-111m-\frac{1}{2}(-141.51m)}{3.8s}=\frac{-111m+70.75m}{3.8s}\\\\v_{o}=\frac{-40.25m}{3.8s}=-10.59\frac{m}{s}[/tex]
Hence, we have that the initial velocity of the object is [tex]-10.59\frac{m}{s}[/tex]

y = 47.9 m
We have that for the Question "A baseball is popped straight up into the air and has a hang-time of 6.25 S.
Determine the height to which the ball rises before it reaches its peak. (Hint: the time to rise to the peak is one-half the total hang-time.)" it can be said that Hence, the height to which the ball rises before it reaches its peak is
S=47.85m
From the question we are told
A baseball is popped straight up into the air and has a hang-time of 6.25 S.
Determine the height to which the ball rises before it reaches its peak. (Hint: the time to rise to the peak is one-half the total hang-time.)
Generally the Newtons equation for the distance is mathematically given as
[tex]s=ut+1/2at^2\\\\\ Where \\\\T=\frac{6.25}{2}\\\\T=3.125\\\\[/tex]
Therefore
[tex]s=0+1/2(9.8)(3.125)^2[/tex]
S=47.85m
Hence, the height to which the ball rises before it reaches its peak is
S=47.85m

(HELP ME PLEASE ;-;) The National Academy of Sciences reported that the Earth's surface temperature has risen by about 1 degree Fahrenheit in the past century. This is an example of a change in Earth's
Climate or Weather?
Answer:
Climate
Explanation:
I am pretty sure this is climate because climate is what the temperature over time while weather is what the temperature is today. For example, it may we windy today. That is an example of weather. It is hot in Arizona and Cold in Idaho. This is an example of climate.
Final answer:
The increase of the Earth's surface temperature by about 1 degree Fahrenheit over the past century is an example of a change in Earth's climate, which is a long-term trend, as opposed to weather which is short-term. This change is indicative of global warming and has profound effects on the environment and living organisms.
Explanation:
The National Academy of Sciences report stating that the Earth's surface temperature has risen by about 1 degree Fahrenheit in the past century is an example of a change in Earth's climate. This rise in temperature represents a long-term trend that affects ecosystems, weather patterns, and geological processes on a global scale. In contrast, weather refers to short-term atmospheric conditions. The concept of global warming is closely related to this change, as it describes the increase in Earth's average surface temperature due to activities such as burning fossil fuels which release gases that warm the planet. Notably, the increase in global temperatures has implications for habitats, species survival, and agricultural practices. Regional variations in climate change are expected, with some areas, like the Arctic, experiencing more rapid warming.
