Calculate the light intensity 1.45 m from a light bulb that radiates 100 w equally in all directions.

I = 3.785 W/m²

Explanation:

given,

distance from the light, r = 1.45 m

Power of bulb = 100 W

The area is that of a sphere with a radius equal to the distance from the light bulb.

The formula for the area of a sphere of radius 1.45 meters is:

A = 4 π r²

A = 4 x π x 1.45²

A = 26.42 m²

Intensity of the light is equal to

      I = 3.785 W/m²

Intensity of the light at 1.45 m is equal to I = 3.785 W/m²

where’s the list ? the question is incomplete

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
