Carlos has eight marbles that are all the same size. he knows that one marble has a mass of 10 grams. to find out the total mass of all his marbles together, he adds 8 tens and gets a total of 80 grams.

A 2.37-kg rock is released from rest at a height of 22.2 m. ignore air resistance and determine (a) the kinetic energy at 22.2 m, (b) the gravitational potential energy at 22.2 m, (c) the total mechanical energy at 22.

The magnetic flux through each turn of a 110-turn coil is given by ΦB = 9.75 ✕ 10-3 sin (ωt), where ω is the angular speed of the coil and ΦB is in webers. At one instant, the coil is observed to be rotating at a rate of 8.70 ✕ 102 rev/min.
