In a cathode ray tube, the accelerating anode is positively charged which can accelerate the electron in cathode ray. why don't the accelerating anode pull back or slow down the electrons after they pass through it?

If the ama of the inclined plane below is 2, calculate the ima and efficiency. ima = efficiency =

Consider two less-than-desirable options. in the first you are driving 30 mph and crash head-on into an identical car also going 30 mph. in the second option you are driving 30 mph and crash head-on into a stationary brick wall. in neither case does your car bounce off the thing it hits, and the collision time is the same in both cases. which of these two situations would result in the greatest impact force?

How much work would it take to move a coulomb charge across a 4 volt potential difference?
