Answer:
0.01125 foot-candles
Step-by-step explanation:
According to the data, intensity of light measured in foot-candles varies inversely with the square of the distance from the light source
Therefore,
α 1/
= k/
where,
'k' is the constant
'd' is the distance from bulb
' ' is intensity of a light bulb
When,
d= 3meters
= 0.08foot-candles
k= .
k= 0.08 x 3² => 0.08 x 9
k= 0.72
Next is to determine the intensity level at 8 meters.
= k/
= 0.72/ 8²
= 0.01125 foot-candles
Therefore, the intensity level at 8 meters is 0.01125 foot-candles
