In a crude model of a rotating diatomic molecule of chlorine (cl2), the two cl atoms are 2.00 ✕ 10-10 m apart and rotate about their center of mass with angular speed ω = 4.20 ✕ 1012 rad/s. what is the rotational kinetic energy of one molecule of cl2, which has a molar mass of 70.0 g/mol?

An object moves from position +34m to the position -15m in 15 seconds. what is the total displacement? what is the total velocity?

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:

Two point charges are separated by a certain distance. how does the strength of the electric field produced by the first charge
