Final answer:
A 100-watt light bulb uses 6,000 joules of energy each minute, as one watt equals one joule per second, and there are 60 seconds in a minute.
Step-by-step explanation:
If you have a 100-watt light bulb, the amount of energy it uses each minute can be calculated by knowing that power is the rate at which energy is used and one watt equals one joule per second. So, a 100-watt bulb uses 100 joules per second. To find out how much energy this bulb uses in one minute, you would multiply the power (100 watts) by the number of seconds in a minute (60 seconds).
100 watts x 60 seconds = 6,000 joules
Therefore, the correct answer is A) 6,000 joules.
