There are four naturally occurring isotopes of the element chromium. The relative abundance of each is
50Cr 4.345% 49.946044 amu
52Cr 83.789% 51.940508 amu
53Cr 9.501% 52.940649 amu
54Cr 2.365% 53.93880 amu
Find the average atomic mass of chromium.

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j

330 wpu is be the right temperature
