Explanation:
It is known that relation between torque and angular acceleration is as follows.
and, I = 
So, 
= 4 
So, 
= 1
as
= 
Hence, 
Thus, we can conclude that the new rotation is 
times that of the first rotation rate.
The answer to this question should be: The accuracy in measuring its velocity decreases

<span>The correct answer is: Chlorofluorocarbons (CFCs)
Explanation:
In simple words, CFCs are the chemical compounds made up of the following three elements:
1. Carbon
2. Chlorine
3. Fluorine
When CFCs compounds reach the upper atmosphere, the ultraviolet rays coming from the Sun break those compounds into individual elements, which then react with one of the oxygen atom of the ozone (O3) to form new compounds like chlorine monoxides. That way the ozone molecules get destroyed, resulting into the ozone depletion. Hence, the correct answer is Chlorofluorocarbons (CFCs).</span>
Momentum is (mass) times (speed), so nothing that is at rest has any momentum. If the battleship is at rest, then a mosquito in flight, a leaf falling from a tree, and your speedy baseball each have more momentum than the ship has.
