Answer:
energy from excess mass
Explanation:
The correct answer for the given question out of the given options is the option " energy from excess mass ".
This happens due to the fact that some of the matter is converted into the energy during the fusion of atoms.
The relation that can be stated is E = mc²
where,
E is the energy

Answer:
The frequency of the wheel is the number of revolutions per second:
f= \frac{N_{rev}}{t}= \frac{10}{1 s}=10 Hz
And now we can calculate the angular speed, which is given by:
\omega = 2 \pi f=2 \pi (10 Hz)=62.8 rad/s in the clockwise direction.
Explanation:
Hope these r correct:
Normal Force≈ 68.5
Frictional Force≈ 20.5
Accel. ≈ 58.5
These are rounded
Answer:
Explanation:
A body has acceleration when there is a change in the velocity vector, either in magnitude or direction. In this case we only have a change in magnitude. The average acceleration represents the speed variation that takes place in a given time interval.
