Question
The energy of the water comes from the change of the potential energy (m g h). What is the needed change in potential energy each second? Answer in units of J/s. 019 (part 3 of 3) 10.0 points If the water falls 17 m, what is the mass of the water that must pass through the turbine each second to supply this power? Answer in units of kg/s. 020 10.0 points TheemfofabatteryisE =16V.Whenthe battery delivers a current of 0.2 A to a load, the potential difference between the terminals of the battery is 14 V volts. Find the internal resistance of the battery. Answer in units of . The energy of the water comes from the change of the potential energy (m g h).

The first part of the question is incomplete !!
20)
e = 16 V
I = 0.2 A
Potential Difference btw Terminals of the battery = 14 v
Let the internal resistance of battery = r
16 - I*r = 14
16 - 0.2 * r = 14
r = 10
