<span>if we take ball then the Kinetic Energy of the ball is ½mV²
as it rolls up the slope, the Kinetic Energy is converted to potential energy, PE = mgh.
mgh = ½mV²
h = V²/2g</span>
Answer:
Los movimientos verticales o circulación convectiva consisten en un intercambio de lugar entre el aire caliente de las capas bajas y el aire frío de las superiores. Este movimiento se debe a la diferencia de densidades de las distintas masas de aire. Los movimientos horizontales se basan en las diferencias de presión.
Explanation:
The centripetal force acting on a particle is given by :
Since, 
Case 1.
If 
Since, 
So, 
So, the force becomes,
F is independent of r
Case 2.
If 
So, 
So, the force is inversely proportional to the square of radius.
Case 3.
If T is independent of r, the force will be directly proportional to the radius of orbit.
Hence, this is the required solution.
