Betty is attempting to lift a 44kg bucket up a vertical distance of 7m using a rope and pulley system. If it takes her 72 seconds to complete the task, determine the power she develops by
her work on the bucket

Determine the maximum r-value of the polar equation r =3+3 cos 0

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf ε. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 ω, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?

Can you match these to the correct definition
