Respuesta :

1 Kilowatt Hour = 3,600,000 Joules
3,600,000 x 32 = 115,200,000

In a year that is 115,200,000 Joules.

Answer: The amount of energy used by television is [tex]1.15\times 10^8J[/tex]

Explanation:

We are given:

Amount of energy used by television per year = 32 kWh = 32000 W h   (Conversion factor:  1 kW = 1000 W)

To convert this into joules, we use the conversion factor:

1 hour = 3600 seconds

1 W = 1 J/s

Converting the energy into Joules, we get:

[tex]\Rightarrow \frac{32000J.hr}{s}\times \frac{3600s}{1hr}\\\\\Rightarrow 1.15\times 10^8J[/tex]

Hence, the amount of energy used by television is [tex]1.15\times 10^8J[/tex]
