Ablock of mass m1 = 290 g is at rest on a plane that makes an angle θ = 30° above the horizontal. the coefficient of kinetic friction between the block and the plane is μk = 0.10. the block is attached to a second block of mass m2 = 200 g that hangs freely by a string that passes over a frictionless and massless pulley. find its speed when the second block has fallen 30.0 cm.

If 2 moles of co_2 at 2l and 500k are expanded reversibly to 20l, more work can be obtained from an adiabatic process than from an isothermal process. is the above statement true or false?

An electron is ejected into a horizontal uniform e⃗ field at a parallel horizontal velocity of v0. assume the electron's initial position x0, initial velocity v0, time t, magnitude of electric field e, electron's mass m, and the magnitude of the electron's charge |e|. ignore the force that earth exerts on the electron. assume the e⃗ field is in the same direction as the initial velocity. part a define the equation for the electron's velocity. express your answer in terms of the variables v0, |e|, t, e, and m.
