The sun generates about 4 * 10 ^ 26 joules of energy every second. There are about 3.15 * 10 ^ 7 sec About how many joules of energy does the sun generate in a year ? Write the answer in scientific notation. Express the answer to the exact decimal place (1 point )

1 answer

To calculate the energy generated by the sun in a year, we need to multiply the energy generated every second by the number of seconds in a year.

Energy generated per second: 4 * 10^26 joules
Number of seconds in a year: 3.15 * 10^7 seconds

To find the total energy generated in a year, we multiply these two values:

Total energy generated in a year = (4 * 10^26 joules) * (3.15 * 10^7 seconds)

Multiplying the values inside the parentheses:

Total energy generated in a year = 12.6 * 10^33 joules

So, the sun generates approximately 12.6 * 10^33 joules of energy in a year.
