In the figures, the masses are hung from an elevator ceiling. assume the velocity of the elevator is constant. find the tensions in the ropes (in n) for each case. note that θ1 = 37.0°, θ2 = 53.0°, θ3 = 59.0°, m1 = 5.00 kg, and m2 = 9.00 kg. (due to the nature of this problem, do not use rounded intermediate values in your calculations—including answers submitted in webassign.)

In which of the following cases is work being done on an object? question 2 options: pulling a trailer up a hill carrying a box down a corridor suspending a heavy weight with a strong chain pushing against a locked door

Aforklift raises a 1,020 n crate 3.50 m up to a shelf. how much work is done by the forklift on the crate? the forklift does j of work on the crate.

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
