Answer:
.
Explanation:
Intensity
of the electromagnetic radiation is given by

where
is the distance from the EM source (the center of the sun, in our case), and
is the power output of the sun and it has the value

Since the radius of the sun in meters is
, the intensity
of the electromagnetic radiation at the surface of the sun is

The intensity of the electromagnetic radiation at the surface of the sun is
.

Answer:
Correct statement will be dragster rounded the curve with constant speed
Explanation:
It is given that his fried says that The dragster rounded the curve with a constant velocity of 100 km/hour
It is a wrong statement because in circular motion velocity will never constant as the direction of speed is always changing
The correct statement will be dragster rounded the curve with a constant speed because speed may be constant in circular motion
