Answer:
Explanation: This is done using the equation:
Because the Radius is a know value. We have the following.
Which is:
4188.7902 mm
Answer:
755.7 seconds
Explanation:
Distance between Sun and Mars = 226.71 * 10^9 m
Speed of light = 3 * 10^8 m/s
Speed = distance/time
Time = distance/speed
Time = (226.71 * 10^9)/(3 * 10^8)
Time = 755.7 s
2.5 watt
Explanation:
we know
power = work done /time
work done gainst gravity is = mgh
as mg = weight = force = 5 N
and height = 2 m
so work done = mgh = 5*2 = 10N
therefore ,
Power = 10/4 = 2.5 watt
