the answer is A. The aluminum has 0.84 ohms more resistance.
Answer:
t = 444.125 sec
Explanation:
Given data:
V = 24 volt
I = 0.1 ampere
mass of water mw = 51 gm
cr = 4.18 J/gm degree K^-1
mass of resistor = 8 gm
cr = 3.7 J/gm degree K^-1
we know that power is given as
Power P = VI
But P =E/t
so equating both side we have

solving for t


t = 444.125 sec
Looks like you need to review through the lesson and take notes as it tells you in the lesson what each of these are.
