Energy from the sun is referred to as solar energy.
So energy from the sun is solar energy.
hope it helps!!!
Answer:
option (d)
Explanation:
Energy is defined as the capacity to do work.
Energy can neither be created and nor be destroyed, it can transform from one form to another.
The SI unit of energy is Joule and teh commercial unit of energy is kilowatt hour.
There are several forms of energy.
1. kinetic energy
2. potential energy
3. mechanical energy
4. Solar energy
5. Sound energy
I don’t know the first one but the second one is light and the third one is a satellite
First we should convert 14.4 km into meters using the conversion factor 1km = 1000m; thus, 14.4 km = 14,400 m. Next, we should convert all minutes into seconds <span>using the conversion factor 1 min = 60 seconds; thus, 40 mins = 2400 seconds while 20 minutes = 1200 seconds.
Speed = distance over time
Amy's speed = 14400 m / 2400 sec = 6m/s
Bill's time is 1200 sec + Amy's which is 2400 sec
Bill's speed = 14400m / 3600 sec = 4 m/s
Therefore, Amy is faster than Bill with 2 m/s difference.</span>
Answer:
Explanation:
Given
mass of ship =1240 kg
height=37 m
(a)Work done by Tension in cable+work done by gravity =0
Work done by gravity =change in potential energy of mass
Thus work done by tension=449.624 kJ
(b)work done by force of gravity
=-449.624 kJ
