Explanation:
Mass will remain unchanged, always. His weight, which is the gravitational force acting on that mass will be less in this case.
An air mass is a large pocket of air with a uniform temperature and humidity
Answer:
∵ 
Explanation:
The tangential acceleration of a cart moving at a constant speed in a circle is:
The angular velocity is constant when the circular speed is constant.
We know that the (instantaneous) tangential velocity of such object is given by:

Now for angular acceleration we have a constant angular speed:

And angular acceleration is related to tangential acceleration as:
