because I did this assignment, :) your welcome
Next time do it by yourself, but here's the answer kid
Answer:A
Explanation:
Given
Two ponies are at Extreme end of turntable with mass m
suppose turntable is moving with angular velocity 
Moment of inertia of Turntable and two ponies
let say at any time t they are at a distance of r from center such 
Moment of inertia at that instant
conserving angular momentum as net Torque is zero
Thus we can say that angular velocity increases as they move towards each other.
A vector would be a quantity that has both magnitude and direction.
Answer:
Because the difference in air temperature of neighbouring air masses causes the wind to blow. Warmer air is less dense, so colder air subsides into the space occupied by the warmer air due to the force of gravity, displacing the warmer air upwards. This is fundamentally the reason temperature change may be accompanied by wind. It is possible to think of situations where only one of these effects is observed at any one place, due to the large size or stationary nature of atmospheric boundary phenomena.
