For 12 density often has unit of grams per cubic centimeter (g/cm3)
Answer:
Intensity = 11.56W/m²
The energy flowing through the given area is 4.55 J
Explanation:
The expression for the intensity of the electromagnetic wave is,

Here,
is the permittivity of the free space,
is the electric field amplitude and
c is the speed of the light.
substitute
⁸m/s for c
8.85×10 −12 C²
/N⋅m² for 
and 93.3 V/m for 

The expression for the energy is,
E = I×A×t
Here, I is the intensity of the electromagnetic wave,
A is the area, and
t is the time.
Substitute
11.56W/m² for I
0.0287m ² for A
13.7s for t

The energy flowing through the given area is 4.55 J
Answer:
<h2>Electric charge</h2>
Explanation:
The rate of the flow of electric charge is known as electric current. <u>By convention, the direction of electric current is always the direction of net flow of positive charge.</u>
Answer:
emf=-0.035V
Explanation:
this problem can be solved with the Lenz's law:

where PhiB is the magnetic flux. In this case we have

due to the magnetic field is constant. A is the area of the circular loop. Hence

Finally

HOPE THIS HELPS!!
Zeros the left of the decimal but still less than one are non significant but to the right they are.
For example: 0.003 (only 3 is significant) but for 0.030 (two are significant)
