What is the speed of a helicopter that traveled 1200 miles in 7 hours
2 answers:
Answer:
The answer is 171 m/h
Explanation:
Speed relates to positional change with time, that is, it expresses the distance traveled in a given time.
The speed is expressed as
The helicopter has to travel 1200 miles (distance) in 7 hours (time). Then we can replace the values in the velocity formula.
Therefore the helicopter speed is equal to 171 m/h

Explanation:
The intensity of light measures the power that the light delivers per unit area.
The source in this question delivers a constant power of . If the source here is a point source, that
of power will be spread out evenly over a spherical surface that is centered at the point source. In this case, the radius of the surface will be 9.6 meters.
The surface area of a sphere of radius is equal to
. For the imaginary 9.6-meter sphere here, the surface area will be:
.
That power is spread out evenly over this 9.6-meter sphere. The power delivered per unit area will be:
.
