Explanation:
The detailed steps and calculation is shown in the attachment.
We can solve the problem by using Ohm's law, which states that an Ohmic conductor the following relationship holds:
where
is the potential difference applied to the resistor
I is the current flowing through it
R is the resistance
In our problem, I=4.00 A and
, so the potential difference is
where
I is the current flowing through it
R is the resistance
In our problem, I=4.00 A and
Answer:
The value of radiation pressure is Pa
Explanation:
Given:
Intensity
Area of piece
From the formula of radiation pressure in terms of intensity,
Where radiation pressure,
speed of light
We know value of speed of light,
Put all values in above equation,
Pa
Therefore, the value of radiation pressure is Pa
