Got stuck again, can anyone help?please show all work so I know hpw to do them!

I need help with this problem and an explanation for the solution described below. (University Physics 1: Thermodynamics: Temperature and Heat).

Does your weight depend on where you are located on the Earth's surface? Yes! Your apparent weight on a scale standing at the equator will be less than your apparent weight while standing on a scale at the North Pole (see figure). This difference occurs due to the Earth's rotation. How much extra mass would a 65.0-kg person have to hold while weighing himself at the equator, so that his apparent weight there is equal to his apparent weight at the North Pole? Number Weight is maximum at poles North Pole Equator Center of earth Force of gravity Weight is minimum at the Equator. Source: Md.

A construction crane with a 42m long horizontal arm carries a load of 5000kg,which is suspended from a trolley that runs along the length of the arm. Thecrane rotates with angular velocity of 0.15 s^-1 . The trolley pulls the load towards the axis of thecrane with a constant horizontal velocity of 0.2m/s relative to the arm. Determinethe magnitude and direction of the Coriolis force acting on the load due to therotation of the crane (the Earth's rotation can be neglected)

The sport Hammer Throw involves a "hammer", which consists of a metal ballattached by a steel wire to a grip. For women, the mass of the ball is 4kg (themass of the steel wire and grip are negligible), and the length of the steel wire is120 cm. Calculate the magnitude of the centrifugal force that acts on the ball fora woman with 50cm long arms, who spins on the spot with an angular velocity of 4(pi)s^-1

An AC voltage source is connected to an inductor with inductance 0.047 H. The voltage source provides a time-dependent voltage V across the inductor as described by V(t) = v0 sin(ωt), where v0 = 251 V and ω = 991 rad/s.   a) Find the current through the inductor, in amperes with its sign, at time t = 1.9 s.    b) Calculate the instantaneous power, in watts with its sign, that the inductor is absorbing at time t = 1.9 s.
