At a construction site, the site manager notices that a crane takes 20 seconds to lift a 500kg steel beam up to a height of 15 m
posledela
The work done is equal to the change in potential energy which is:
P.E = mgh
P.E = 500 x 9.81 x 15
P.E = 73,575 J

Power = work / time
Power = 73,575 / 20
Power = 3,700 Watts

What is transferred by all types of waves? A. energy B. electrons C. heat D. matter
djyliett [7]
<span>The question is what do all types of waves transfer. Waves, both mechanical and electromagnetic are disturbances that transfer energy without transporting matter. It doesnt matter wether they are propagating trough a medium or trough vacuum. Therefore the correct answer is A. energy.</span>

Lance Armstrong bikes at a constant speed up the Col d’Izoard, a famous mountain pass. Assume his teammates do such a good job r
svetoff [14.1K]

Work done against gravity to climb upwards is always stored in the form of gravitational potential energy

so we can say

W = mgh

here h = vertical height raised

so here we know that

h = 14.1 sin7.3 km

here we have

h = 1.79 km

now from above equation

W = (83 kg)(9.81 m/s^2)(1.79 \times 10^3 m)

W = 1.46 \times 10^6 J

so work done will be given by above value
