Is "noble gas" a compound or an element? i'm confused : /

Ithink the answers is b i hope it my friend message me if i’m wrong and i’ll change my answer and fix it for you

Iwas going to ask that quesytion  sorry dude i dont  know : (    : /

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

The answer is d, you can easily test a theory! hope i you : )
