Problem: You have two blocks with masses m1 and m2 suspended from a string looped over a pulley. The blocks are both initially a distance h from the floor and start at rest.
Part A: If m1 < m2, how long does it take m2 to hit the floor?
I need expert help to solve the above question and write an expression in terms of h, m1, m2, and g.
A light string that does not stretch changes from horizontal to vertical as it passes over the edge of a table. The string connects m1, a 3.4 kg block, originally at rest on the horizontal table at a height 1.27m above the floor, to m2, a hanging ..
A microwave oven can heat 205 of water from 20.0 to 90.0 in 2.00 . If the wavelength of the microwaves is = 15.2 , how many photons were absorbed by the water?
How much current would flow if you directly connected a 20Ω resistor to a 0.01 Volt battery? What would this 500 μA meter read if it was inserted into this circuit ( in series)? Would the internal resistance of the 500 μA meter significantly alter..

Consider a block of mass m sliding down an inclined plane andit has three forces acting on it (1) a gravitational force(pointing down). (2) a normal force perpendicular to the surface ofthe plane. (3) a friction force opposing motion down the plan..
Two identical blocks of mass m are connected by a cord of length l that runs over a massless frictionless pulley, as shown below. One mass sits on a frictionless horizontal table. Now suppose that the string has a total mass M, which is distributed u..
