Answer:
Explanation:
Centripetal force acts towards the center of the circle. However, our body is not attached to the car, it is only kept in the car. Therefore, when an external force acts on the car, inertia acts on the body due to the sense that it will try to remain in the same state.
Although the car takes the turn, but due to the inertia, the body will try to move forward; but since the seat belts are on, it is enforced to move with the car in a circular motion
The speed of light in glass is slower than the speed of light through space.
Answer:
point in the same direction as the change in position.
require knowing the initial and final position, along with the elapsed time.
Explanation:
As we know that average velocity is defined as the ratio of change in position and the time interval of the object
It is given as
so we will have
= displacement
= time interval
the direction is this average velocity is always along the direction of the displacement
so correct answer will be
point in the same direction as the change in position.
require knowing the initial and final position, along with the elapsed time.
Explanation:
A-It starts to expand. Hence ice and water of same weight has different volumes
Momentum= mass*velocity thus if you keep velocity constant an increase in mass increases momentum so the heavier object (assuming constant gravity) has a higher momentum than a lighter object
