Question

he light energy that falls on a square meter of ground over the course of a typical sunny day is about 20 MJ. The average rate of electric energy consumption in one house is 1.0 kW. Part A On average, how much energy does one house use during each 24 h day? Express your answer in joules.

Answer 1

`E = 86.4 * 10^6 J`

Step-by-step explanation:

Given data:

light energy = 20 MJ

Electric consumption is 1.0 kW

Duration of energy consumption is 24 hr

Energy consumption is given as

`E = Power * time`

`E = 1 * 10^3 * 24 * 3600`

`E = 8.64 * 10^6 J = 86.4 MJ`

`E = 86.4 * 10^6 J`
