Answer:
The angular velocity at the beginning of the interval is 
.
Explanation:
Given that,
Angular acceleration 
Angular displacement 
Angular velocity 
We need to calculate the angular velocity at the beginning
Using formula of angular velocity
Where, 
= angular acceleration
= angular velocity
Put the value into the formula
Hence, The angular velocity at the beginning of the interval is .
Answer:
solar, wind, hydro, natural resources
For the first hour, the slope is zero.
After that, the slope is -2 miles per hour.
Answer:
The correct option is;
A. The potential energy between both like charges and like poles increases as they move closer together
Explanation:
Here we have that when we move the like poles of two bar magnets close to each other, there is an increased resistance in the continuing motion, therefore for each extra gap closer achieved, there is an increase in potential energy
Similarly, when two like charges are brought closer together, the potential energy, or the energy available to push the two like charges apart increases charge as the as the charges are brought closer together
Therefore, the correct option is the potential energy between both like charges and like poles increases as they move closer together.
