Answer:
Value of angle between vector a and b is
.
Explanation:
Vectors a and b have scalar product 6.00
Let
be the angle between a and b.

ab cos
= 6 ...(1)
Vectors a and b have magnitude of vector product 9.00

ab sin
= 9 ...(2)
Dividing equation (2) by (1) we get

tan
= 1.5

= 
Thus, value of angle between vector a and b is
.
Answer:
1.907 x 10⁻⁵ J.
Explanation:
Given,
Volume of space, V = 5.20 m³
Assuming the intensity of sunlight(S) be equal to 1.1 x 10³ W/m².
Electromagnetic energy = ?


where c is the speed of light.


Hence, Electromagnetic energy is equal to 1.907 x 10⁻⁵ J.
Thew energy stored in a capacitor of capacitance
and voltage between the plates
is
.
Substituting numerical value

Most likely it would be C not completely sure
I'm pretty sure what you are trying to ask for is radiative energy, light energy, and electronic energy.
Radiative since the microwave is releasing radiation,
Light since there is light inside the microwave,
Electronic since it is plugged in and uses electricity.
You can also use sound, but I don't think every microwave makes sound.
