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

Answer:

$E = 86.4 \times 10^6 J$

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

$E = Power \times time$

$E = 1 \times 10^3 \times 24 \times 3600$

$E = 8.64 \times 10^6 J = 86.4 MJ$

$E = 86.4 \times 10^6 J$
