I need a little help on this. A gardener pushes on the angled handle of a lawn mower, causing it to move forward across a lawn. Which portion of the gardener’s force is doing work on the lawn mower? the force in the vertical direction

the force of the lawn against the lawnmower

the force in the horizontal direction

the force opposite the force of gravity

What causes the formation of ocean currents?

Of is j/kg·k. if a 2.6 kg of isk to k, is ?

A200-n force is applied to the foot-operated air pump. the return spring s exerts a 2.6-n·m moment on member oba for this position. determine the corresponding compression force c in the cylinder bd. if the diameter of the piston in the cylinder is 40 mm, estimate the air pressure generated for these conditions. state any assumptions. enter a positive number for the compression force c.
