The electric potential inside a parallel-plate capacitor the electric potential inside a parallel-plate capacitor decreases linearly from the negative to the positive plate decreases inversely with the square of the distance from the negative plate is constant increases linearly from the negative to the positive plate decreases inversely with distance from the negative plate

Aroller coaster car moving at a velocity of 30 meters/second has a momentum of 2.5 x 10^4 kilogram meters/second. what is its mass?

There are weak or strong attractive forces between atoms of liquids with a high viscosity

Consider a double atwood machine constructed as follows: a mass 4m is suspended from a string that passes over a massless pulley on frictionless bearings. the other end of this string supports a second similar pulley, over which passes a second string supporting a mass of 3m at one end and m at the other. using two suitable generalized coordinates, set up the lagrangian and use the lagrange equations to find the acceleration of the mass 4m when the system is released. explain why the top pulley rotates even though it carries equal weights on each side.
