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.
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]
