Explanation:
Given that,
Average power of sun
We need to calculate the intensity of light at Earth's position
Using formula of intensity
Where, I = intensity
P = power
Put the value into the formula
So, The intensity is 1347.616 W/m².
(A). We need to calculate the pressure on a solar sail due to the light of the sun if it's fully reflective
Using formula for fully reflective
Put the value into the formula
(B). We need to calculate the pressure on a solar sail due to the light of the sun if it's fully reflective
Using formula for fully absorptive
Hence, This is the required solution.
Answer:
Work done will be 2.205 j
Explanation:
We have given that the spring is compressed b 37.5 cm
So d = 0.375 m
Mass of the block m = 600 gram = 0.6 kg
Acceleration due to gravity
Gravitational force on the block
Now we know that work done is give by
