Aheater uses 20 amperes when connected to a 110-volt electric outlet. if electric power costs 10 cents per kilowatt-hour, the cost of running the heater for 10 hours

$ 2.2

Explanation:

Current, i = 20 A

Voltage, V = 110 V

time, t = 10 hours

Cost of 1 KWh = 10 cents

Energy cosumed in 10 hours

E = V x i x t

E = 110 x 20 x 10 Wh

E = 22 KWh

Cost of 1 KWh = 10 cents

Cost of 22 KWh = 10 x 22 = 220 cents = $2.2

Thus, the ost of heater running for 10 hours is $ 2.2

$2.2

Explanation:

Electric power in watts = Voltage times amparage

P=VI

V=110 V

I= 20 A

P= 110×20= 2200 W

Power consumed in 10 hours = 2200×10= 22000 Wh= 22kWh

total cost of 22kWh consumption= 22×0.10= $2.2

i feel your pain too because i cant find my dad and hes been missing for 17 years of my life

explanation:

he went to the supermarket with your dad

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.
