In 2006, the united states produced kilowatt-hours (kwh) of electrical energy from 4138 hydroelectric plants (1.00 kwh = j). on average, each plant is 90% efficient at converting mechanical energy to electrical energy, and the average dam height is 50.0 m. as water flows through the hydroelectric plant apparatus, it maintains constant speed all the way to the bottom. a) what was the average power output per hydroelectric plant, for the year of 2006? b) what was the volume of water that flowed over each dam during 2006? (the density of water is 1000 .)

(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?
