Electrons are accelerated in a Television tube through a potential difference of about 10 kV. Find (i) the highest frequency of the EM waves emitted, when these electrons strike the screen of the tube (ii) what kind of waves are these? ​

Where is the table ? you can take a picture of it

It is d, all the other ones say incorrect answer .

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
