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 .
Answer:
B. The image is right-left reversed and about as far away from the mirror as the reflected object.
Explanation:
A plane mirror is used in several ways in our life, from the mirror that we have on the bathroom to the mirrors we use on cars, the main difference is that the mirror reflects the image reversed on the Vertical axis, which means that the left is the right and the right is the left, a mirror also protrays objects at a certain distance, about as far away from the mirror as the reflected object but they are actually closer in real life.

Answer:
= 729 Joules
Explanation:
Heat absorbed by a substance is given by the formula;
Q = m×c×ΔT
Where; Q is the heat absorbed
m is the mass of the substance
ΔT is the change in temperature;
The specific heat capacity of iron is 450 J/Kg/K
Therefore;
Heat absorbed = 0.06 kg × 27 × 450
= 729 Joules
