Electric current is the movement of electrons through a wire. Electric current is measured in amperes (amps) and refers to the number of charges that move through the wire per second.
Answer:
58.703 ft/centuri
Explanation:
Length of the hair grow, l = 0.49 mm
Time to grow, t = 1 day
Convert mm into feet.
We know that, 1 mm = 0.00328 feet
So, 0.49 mm = 0.49 x 0.00328 = 0.0016072 ft
Convert day into century.
We know that, 1 century = 36525 days
So, 1 day = 1 / 36525 centuri
growth rate of hair =
= 58.703 ft/centuri
