Assume you get a summer job as a crane operator. on the first day you are lifting a heavy piece of machinery. even though you have the arm at 70∘ above the horizontal, the crane begins to tip slowly forward. consider the following possible actions: release the brake on the lifting cable so that the load accelerates downward. release the lifting arm so that θ decreases rapidly and the load accelerates downward. increase θ while simultaneously letting out the lifting cable so that the load accelerates downward. put the crane wheels in gear and accelerate the crane forward. none of these solutions is ideal, but which will have the short-term effect of restoring contact of the crane's rear wheels with the ground? a) all but 1 b) all but 2 c) all but 3 d) all but 4 e) all of them

The discovery of the electron as a subatomic particle was a result of

1. study the scenario. the particles in some system are moving around quickly. a few minutes later, the particles are moving, on average, more slowly. how does this change in motion affect the temperature of the system? the temperature of the system did not change. the speed of the particles does not affect temperature, the number of particles affects the temperature. the temperature of the system is lower now than it was initially. faster moving particles result in a higher temperature for the system. the temperature of the system is higher now than it was initially. slower moving particles result in a higher temperature for the system. the temperature of the system did not change. the speed of the particles has no effect on the temperature, only the type of atom affects the temperature.

As more bulbs are added to a series circuit what happens to the resistance of the circuit
