Answer:
The intensity of the light from the bulb would be
3.501 x W/
Explanation:
Given
The Power = 110 n W = 110 x W
the distance r = 50 mm = 50 /1000 = 0.05 m
The intensity can be obtained with the relationship below;
I = Power/area ......1
The area of the sphere would be used in this case since the bulb is spherical; A=4π
Putting it into equation 1, we have;
I = P/ 4π
I = 110 x / 4 x π x
I = 3.501 x W/
Therefore the intensity of the light from the bulb would be
3.501 x W/
