What formula would you use to find the image distance for an object 3 cm tall that is placed 50 cm from a converging lens having a focal length of 15
cm?

A. they hold atoms  together with a molecule.its a force that exist between molecules. hope this .

A) acceleration. this seems to be the one that makes sense.

Sorry i don’t know what to do

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
