Answer:
1440 W
Explanation:
The power drawn by a voltage source is the rate of energy consumed, and it can be written as:
where
V is the voltage
I is the current
P is the power
For the source in this problem we have:
I = 12 A is the current
V = 120 V is the voltage of the source
Solving for P, we find the power:
T = 0.017 s
From the foot to the brain is almost the same as the height. We are not given the height of the woman, but to find "about" how much time, we need a height to work with.
She *could* be 1.7 m <- height = distance
Formula for speed, where k = speed, d = distance, t = time
k = d/t
Rearrange to solve for time:
t = d/k
Substitute known values:
t = (1.7 m) / (100 m/s)
Solve:
t = 0.017 s
Therefore, it takes about 0.017s for the impulse to travel from the foot to the brain.
