Refer to Figure 7-2(d). If a force of 200 N is required to lift a 50 kg load, find the IMA, AMA, and efficiency for the system.
(Fw = 100 N)

How does the amount of energy required to hold each proton and neutron in the nucleus compare to the energy released when they are removed?

What would be the result of an alpha particle coming into a magnetic field? a) the alpha particle will stop moving. b) the alpha particle will reverse its direction. c) the alpha particle will be deflected in a curve path. d) the alpha particle will continue to travel in a straight line.

Apositive charge moves in the direction of an electric field. which of the following statements are true? check all that apply. check all that apply. 1.the potential energy associated with the charge decreases. 2. the electric field does positive work on the charge. 3. the electric field does negative work on the charge. 4. the potential energy associated with the charge increases. 5. the electric field does not do any work on the charge. 6. the amount of work done on the charge cannot be determined without additional information.
