Answer:
2.0491 watt per meter square
Step-by-step explanation:
We are given the following in the question:
The intensity of light is given by:

where W is the wattage of the light bulb and r is the distance to the light bulb.
We have to evaluate the intensity of bulb with W = 100 watts and r = 2 meters.
Putting values, we get,

Thus, the intensity of light bulb is 2.0491 watt per meter square.
Step-by-step explanation:
Since, every integer can be expressed as rational number.

Answer:
682,000 miles
Step-by-step explanation:
Using the ratio of 186,000 miles per second:

we can set up a proportion (equivalent ratios) to find the distance, in miles, from the earth to the moon
where 'x' is the number of miles between the earth and the moon
Cross-multiply: x = 186,000*
Solve for x = 682,000 miles
Answer:
40
Step-by-step explanation:
Answer:
64.01
Step-by-step explanation:
tan∅= p/b
tan58= x/40
or, x= 40×tan58
x = 64.01
