Question

How much energy does a little 100-watt bulb use in one hour? ( 1 watt= 1 joule/s)

Answer 1

A 100-watt bulb uses 360,000 joules of energy in one hour, calculated by multiplying its power consumption of 100 watts by the number of seconds in an hour (3600).

Step-by-step explanation:

A 100-watt bulb uses energy at a rate of 100 joules per second. To calculate how much energy it uses in one hour, we multiply the power consumption (100 watts) by the time in seconds (3600 seconds in one hour). Therefore, the energy consumption of a 100-watt bulb in one hour is:

100 watts × 3600 seconds = 360,000 joules

This means that a 100-watt bulb uses 360,000 joules in one hour.
