Consider the following four cases of a person applying force to an object: (1) a force of 5 N directed parallel to the floor is pulling a box over a distance of 1 m.

What is the maximum possible torque on a sphere if the electric field between the transparent plates is 4.4*105 n/c?

If the phase angle for a block-spring system in SHM is ϕ and the block's position is given by x = xm cos (ωt + ϕ), what is the ratio of the kinetic energy to the potential energy at time t = 0? (Use any variable or symbol stated above as necessary.)
