<span>Plate tectonics suggest that the lithosphere floats and moves on the asthenosphere.</span>
Explanation:
The given data is as follows.
Electric field between plates without dielectric, 
Electric field between the plates with dielectric, 
.
Permittivity of free space, 
= 
Now, we will determine the charge density as follows.
= 
= 
Thus, we can conclude that the charge density on each surface of the dielectric is .
D: Ultraviolet Rays is the answer hope that helps
Answer:
The car C has KE = 100, PE = 0
Explanation:
The principle of conservation of energy states that although energy can be transformed from one form to another, the total energy of the given system remains unchanged.
The energy that a body possesses due to its motion or position is known as mechanical energy. There are two kinds of mechanical energy: kinetic energy, KE and potential energy, PE.
Kinetic energy is the energy that a body possesses due to its motion.
Potential energy is the energy a body possesses due to its position.
From the principle of conservation of energy, kinetic energy can be transformed into potential energy and vice versa, but in all cases the energy is conserved or constant.
In the diagram above, the cars at various positions of rest or motion are transforming the various forms of mechanical energy, but the total energy is conserved at every point. At the point A, energy is all potential, at B, it is partly potential partly kinetic energy, However, at the point C, all the potential energy has been converted to kinetic energy. At D, some of the kinetic energy has been converted to potential energy as the car climbs up the hill.
Therefore, the car C has KE = 100, PE = 0
