You raise a bucket of water from the bottom of a deep well at a constant speed. If your power output is 111 W, and the mass of the bucket and the water in it is 3.00 kg, with what speed can you raise the bucket

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?

It is really hard for me right know
