A loudspeaker of mass 16.0 kg is suspended a distance of h = 1.80 m below the ceiling by two cables that make equal angles with the ceiling. Each cable has a length of l = 4.00 m .

What is the tension T in each of the cables?
Use 9.80 m/s2 for the magnitude of the free-fall acceleration.

What is the length x of the side of the triangle below? (hint: use the cosine function)

Does heating a metal wire increase or decrease its electrical resistance? why?

Choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. a 1.0 kg block is placed on top of a 2.0 kg block. a horizontal rope pulls the 2.0 kg block across a frictionless floor with a force of 21.0 n. the coefficient between the two blocks is 0.75. does the 1.0 kg block on top slide?
