If it takes you 5 minutes to dry your hair using a 1200-W hairdryer plugged into a 120-V power outlet, how many Coulombs of charge pass through your hair dryer

The charge pass through your hair dryer is 3000 C.

Explanation:

Given that,

Power = 1200 W

Voltage = 120 V

Flow time = 5 min

We need to calculate the current

Using formula of power

Put the value into the formula

We need to calculate the charge pass through your hair dryer

Using formula of current

Put the value into the formula

Hence, The charge pass through your hair dryer is 3000 C.

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.

0.11 m/s and 0.28 m/s should be correct
