A geothermal air conditioning system for a small house in Upstate New York calls for cooling water at a rate of 1.3 kg/s from 24 C o to 16 C o . The house is located on a lake where the average temperature 7 m below the surface during the summer months is 14 C o . Design a heat exchanger to take the necessary energy from the geothermal cooling system water.

(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?
