You are given a thin rod of length 1.2 m and mass 2.4 kg, a small lead weight of 0.20 kg, and a not-so-small lead weight of 1.0 kg. the rod has three holes, one in each end and one through the middle, which may either hold a pivot point or one of the lead weights. how do you arrange these objects so that the resulting system has the maximum possible moment of inertia? place the pivot point in one end, the 1.0 kg lead weight in the middle, and the 0.20 kg lead weight in the remaining hole. place the pivot point in one end, the 0.20 kg lead weight in the middle, and the 1.0 kg lead weight in the remaining hole. place the pivot point in the middle, the 0.20 kg lead weight in one end, and the 1.0 kg lead weight in the remaining hole. what is that moment of inertia (in kg · m2)?

Explain in physical terms how a microwave oven works. what would happen when you put a conductor in the microwave oven? explain.

Athin plate moves between two parallel, horizontal, stationary flat surfaces at a constant velocity of v = 7.5 m/s. the two stationary surfaces are spaced 4 cm apart, and the medium between them is filled with oil whose viscosity is 0.9 n·s/m2. the part of the plate immersed in oil at any given time is 2 m long and 0.5 m wide. if the plate moves through the mid-plane between the surfaces, determine the force required to maintain this motion. what would your response be if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top surface (h1)? if the plate moves through the mid-plane between the surfaces, the force required to maintain the motion will be n. if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top (h1) surface, the force required to maintain the motion would be n.

Will give brainliest! jay rides his 2.0-kg skateboard. he is moving at speed 5.8 m/s when he pushes off the board and continues to move forward in the air at 5.4 m/s. the board now goes forward at 13 m/s. a. determine jay’s mass. b. determine the change in the internal energy of the system during this process.(express your answer to two significant figures and include the appropriate units.)
