Question

A 60-W light bulb is operated for an average of 5 hours per day. How much energy does the bulb consume in joules each day?

Answer 1

To find the energy consumed by the 60-W light bulb in joules each day, you can multiply the power of the bulb by the operating time in seconds. The energy consumed by the bulb is 1,080,000 joules.

Step-by-step explanation:

To find the energy consumed by the 60-W light bulb in joules each day, we can use the formula:

Energy (in joules) = Power (in watts) x Time (in seconds)

First, we need to convert the average operating time of the bulb from hours to seconds. There are 3600 seconds in 1 hour. So, 5 hours = 5 x 3600 seconds = 18,000 seconds.

Now, we can calculate the energy consumed:

Energy = 60 W x 18,000 s = 1,080,000 joules

Therefore, the 60-W light bulb consumes 1,080,000 joules of energy each day.
