Two workers unload a 100 kg bed frame from a truck whose bed is 1.04 m above the ground. They carry it up 5 flights of stairs (each flight is 2.5 m tall) to Larry's apartment. When they get there, Larry tells them that
he never ordered a bed frame. After some confusion and heated words, the workers take the bed frame
back down the stairs and put it back on the truck.
Calculate the net work done by the workers on the bed in this process. Report you answer to the nearest kJ.

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?

In an experiment, how can i change human errors? be specific.

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.
