A round asteroid has a surface gravity of .0288 m/s^2 if the mass of the asteroid is 1.10 x10^18 kg what is its radius
Answer:
r = 50.47 x 10³ m = 50.47 km
Explanation:
Using the formula for the acceleration due to gravity:
[tex]g = \frac{Gm}{r^2}[/tex]
where,
g = acceleration due to gravity on the surface of asteroid = 0.0288 m/s²
G = Universal Gravitational Constant = 6.67 x 10⁻¹¹ Nm²/kg²
m= mass of asteroid = 1.1 x 10¹⁸ kg
r = radius of asteroid = ?
Therefore,
[tex]0.0288\ m/s^2 = \frac{(6.67\ x\ 10^{-11}\ Nm^2/kg^2)(1.1\ x\ 10^{18}\ kg)}{r^2} \\\\r = \sqrt{\frac{(6.67\ x\ 10^{-11}\ Nm^2/kg^2)(1.1\ x\ 10^{18}\ kg)}{0.0288\ m/s^2}}[/tex]
r = 50.47 x 10³ m = 50.47 km
Answer:
5.05x10^4
Explanation:
g=(GM)/r^2, so
.0288=(6.67x10^-11*1.10x10^18)/r^2, r=5.05x10^4.
This is correct on Acellus.

Two 0.5 kg carts,one red and one green ,sits about half a meter apart on a low friction track. You push on the red with a constant force of 4N for 0.17m and then remove your hand. The cart moves 0.33 m on the track and then strikes the green cart. What is the work done by you on the two cart system?
Answer:
Work done on the two cart system is 2 N-m
Explanation:
Work done is equal to the product of force and displacement
Work done =4N * (0.17 +0.33)
work done = 4N * 0.5
Work done = 2 N -m
Work done on the two cart system is 2 N-m
9. What would be an objects weight on Jupiter, if acceleration due to
gravity on Jupiter is 24.5 m/s/s and the object's mass is 5 kg.
Answer:
Fj / Fe = 24.5 / 9.8 acceleration on Jupiter / acceleration on Earth
Fj / Fe = 2.5
Fj / Fe = 2.5 force on Jupiter = 2.5 that on Earth
W = F = M a
W Jupiter) = 5 kg * 9.8 m/s^2 * 2.5 = 122.5 N
or more simply
F = M a = 5 kg * 24.5 m/s^2 = 2=122.5 N

The bike you are riding hit a pothole in the street and stops quickly but you fly forward over the handlebars. What law of motion is this?
Answer: 1 st law of motion
Explanation:
Given
The bike hits the pothole and the driver flies over the handlebar. This can be explained by Newton's first law of motion. This law states that a body in the state of rest or motion will remain in that state unless an external force is applied to it.
Here, the bike instantly comes to rest by contacting the pothole which is at rest. while the driver body continues to move in forward direction and as a result it flies over the handlebars.
free fall is possible on lunar but not on earth surface.Why?
Answer:
The earth has more gravity so that means if you jump out of a plane without a parachute u will die. But the moon has less gravity so u will not die when hit ground. But someone can probally explain it better than me.
More gravity equals more speed in some cases like falling

Which of these increases the kinetic energy of a car the most?
A. Doubling the mass
B. Doubling the velocity
C. They are the same
Answer:
A. Doubling the mass
Explanation:
Doubling the mass increases the kinetic energy of a car the most.
Doubling the mass increases the kinetic energy of the car.
What happens to a car when the kinetic energy is increased?The energy possessed by a body due to its motion is known as the kinetic energy.The kinetic energy completely depends upon the object's mass and velocity.The unit of kinetic energy is Joule.The formula is K.E = 1/2 mv².The unit of mass is kilogram (kg), then the unit of velocity is meter/ second. (m/s)1 Joule = 1 Kg m²/ s².
As we know the formula, Kinetic energy is equal to half of the product mass and velocity. If mass doubled then kinetic energy also gets doubled.Here, If the car was moving, there will be some kinetic energy as it has the particular mass and speed ( velocity).The kinetic energy of a car increases if the mass gets doubled.Hence, Option A is the correct answer.

Which of the following is a property of an ionic compound?
A
has a low boiling point
B
forms molecules
C
is soft and flexible
D
conducts electricity when aqueous
Answer:
D
Explanation:
ionic compounds conduct electricity when molten or dissolved in water. ionic compounds conduct electricity when dissolved in water because water molecules are attracted to ions, this weakens the strong electrostatic forces of attraction between the oppositely charged ions. thus, ions are pulled away from the lattice structure and the remaining compound dissolves in water to form aqueous solution. The presence of free moving ions enables the ionic compound to conduct electricity.

The given statement is true when you look at your speedometer and it reads 60 mph this is your instantaneous speed.
What is Speed ?In everyday language, most people use the terms speed and velocity interchangeably. In physics, however, they do not have the same meaning and are distinct concepts. One major difference is that speed has no direction; that is, speed is a scalar.
We can calculate the average speed by finding the total distance traveled divided by the elapsed time:
Average speed=Total distance=Elapsed time.
Average speed is not necessarily the same as the magnitude of the average velocity, which is found by dividing the magnitude of the total displacement by the elapsed time. For example, if a trip starts and ends at the same location, the total displacement is zero, and therefore the average velocity is zero. The average speed, however, is not zero, because the total distance traveled is greater than zero. If we take a road trip of 300 km and need to be at our destination at a certain time, then we would be interested in our average speed.
However, we can calculate the instantaneous speed from the magnitude of the instantaneous velocity:
Instantaneous speed
=|v(t)|.
If a particle is moving along the x-axis at +7.0 m/s and another particle is moving along the same axis at −7.0 m/s, they have different velocities, but both have the same speed of 7.0 m/s. Some typical speeds are shown in the following table.
We have now seen how to calculate the average velocity between two positions. However, since objects in the real world move continuously through space and time, we would like to find the velocity of an object at any single point. We can find the velocity of the object anywhere along its path by using some fundamental principles of calculus. This section gives us better insight into the physics of motion and will be useful in later chapters.

Jasmine is investigating the effect force has on the motion of an object. She predicts if she puts a strong force on pushing a bowling ball, it will travel a farther distance than when a weak force is applied. Is her prediction correct? No, a weak or a strong force applied to the ball is unable to affect the motion of the ball. No, the force applied to the bowling ball should be a strong force. Yes, the force applied to the bowling ball affects the motion of the ball. Yes, the ball will travel a longer distance when a weak force is applied.
Answer:
I would like to attach options to the question above for clarity.
Jasmine is investigating the effect force has on the motion of an object. She predicts if she puts a strong force on pushing a bowling ball, it will travel a farther distance than when a weak force is applied. Is her prediction correct?
A. No, a weak or a strong force applied to the ball is unable to affect the motion of the ball.
B. No, the force applied to the bowling ball should be a strong force.
C. Yes, the force applied to the bowling ball affects the motion of the ball.
D. Yes, the ball will travel a longer distance when a weak force is applied.
The correct option is C (Yes, the force applied to the bowling ball affects the motion of the ball).
Explanation:
First, a force is any effort either push or pull that causes an object to undergo a change.
A bowling ball can remain at rest or in motion except a force acts on it. This brings us to the question above, the mass which affects force is not mentioned which means it is uniform or negligible. Recall that force = mass X acceleration. So the greater the force that is applied to the bowling ball the further distance it will travel. From the question, she applied a forward force (pushing), so the more force she applies the further the bowling ball will travel.
