Answer:
B.the same as Lily's.
Explanation:
When a disc is rotating on its axis uniformly with some angular velocity , every particle on it rotates with the same angular velocity , because every particle on it completes a rotation simultaneously . So in one rotation they take same time . Hence particles whether on the outer edge or near the axis , all have same angular velocity .
They but differ due to their different linear velocity . Linear velocity of particle near outer edge have greater magnitude. .
Answer:
The distance travelled does not depend on the mass of the vehicle. Therefore, 
Explanation:
This deceleration situation can be analyzed by means of Work-Energy Theorem, where change in translational kinetic energy is equal to the work done by friction:
(1)
Where:
- Mass of the car, in kilogram.
- Initial velocity, in meters per second.
- Coefficient of friction, no unit.
- Travelled distance, in meters.
Then we derive an expression for the distance travelled by the vehicle:


As we notice, the distance travelled does not depend on the mass of the vehicle. Therefore, 
The sun's energy flow through the earth's system by it moving through the earth's atmosphere.
Answer:
your answers are correct i have done this many times
A small ball and a larger ball with greater mass are dropped from a roof. The larger ball strikes the ground with greater force than the smaller ball.
