The time taken would be 0.5 seconds at a high rate of speed.
Answer:
The centripetal acceleration of the rock is decreases by a factor of 3.
Explanation:
Given that,
Radius of circle
Time period = T
Radius of new circle
We need to calculate the velocity
Using formula of velocity
The time period for new circle
The time period remains same.
Put the value in the equation
The acceleration of the rock is
We need to calculate the acceleration of the new rock
Using formula of acceleration
Put the value into the formula
Hence, The centripetal acceleration of the rock is decreases by a factor of 3.
Explanation:
Absorbing heat from the sun rather than reflecting.
