Work:
1 kilometer = 1000 meters
45 × 60 = 2700
W = F × D
W = 2,000 N × 1,000 m
W = 2,000,000 J
P = W ÷ t
P = 2,000,000 J ÷ 2,700 s
P = 741 watts
Answer:
741 watts of horse power.
Raising the hook, or load by exactly 1 meter, will allow the length of the compressed material regain its original length, provided it wasn't deformed by the 5% compression.
<h3>Hooke's law </h3>
Hooke's law states that the force applied to an elastic material is directly proportional to the extension of the material provided that the elastic limit of the material is not exceeded.
When the length of the material is compressed by 5%, the material will regain its original size and shape when the applied load is removed, if the material was not deformed by the compression.
Thus, raising the hook, or load by exactly 1 meter, will allow the length of the compressed material regain its original length, provided it wasn't deformed by the 5% compression.

his displacements are given as
East
North
now we can find the direction of displacement by using the concept
magnitude of displacement is given as
<em>so the displacement is 17 km at angle 28.1 degree North of East</em>
Answer:
efficiency = useful energy out ÷ total energy in (for a decimal efficiency)
or.
efficiency = (useful energy out ÷ total energy in) × 100 (for a percentage efficiency)
