The answer is convex image
The answer would be 4, each kinetic equation has 4 variables
From Ohm's law: R = V / I
Resistance = (voltage) / (current)
The first paragraph TELLS you that the current is always 0.5 A, and the table tells you the voltage across each piece of wire.
Again . . . <em>R = V / I</em>
Answer:

Explanation:
Energy consumed by 11 W energy efficient fluorescent bulb is given as

now we can say


now total cost of the energy used is given as


Now for conventional 40 W bulb we can say

now we can say


now total cost of the energy used is given as


So total money saving is given as
