Answer:
(a). The average speed is 51.83 m/s.
(b). The average velocity over one revolution is zero.
Explanation:
Given that,
Angular velocity = 110 rev/m
Radius = 4.50 m
(a). We need to calculate the average speed
Using formula of average speed
(b). The average velocity over one revolution is zero because the net displacement is zero in one revolution.
Hence, (a). The average speed is 51.83 m/s.
(b). The average velocity over one revolution is zero.
The portion of the flux leaves the curved surface of the cylinder is 60%.
<h3 /><h3>What are electrons?</h3>
The electrons are the spinning objects around the nucleus of the atom of the element in an orbit.
If a point charge is located at the center of a cylinder and the electric flux leaving one end of the cylinder is 20% of the total flux leaving the cylinder.
If 20% of the flux leave from one end, then another 20% will leave from another end.
So, the net flux through curved surface is
100 -20 -20 = 60%
Thus, the total flux leaves the curved surface of the cylinder is 60%

Answer:
The correct option is;
E. motion of tectonic plates.
Explanation:
The Moon is formed from the Earth, and so have similar composition. However, the smaller size of the moon as well as the low temperature of the Moon's mantle compared to the interior of the earth, contribute the state of the Moon having no active tectonic plate motion and no convection.
The convection in the mantle, drives Earth's tectonic plate motions. The mantle within Earth moves at a rate of some centimeters annually, while the Moon, geologically is a dying world.
