To find the total energy generated by the sun in a year, we need to multiply the energy generated per 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
Total energy generated in a year = (4 * 10^26 joules) * (3.15 * 10^7 seconds)
To multiply numbers in scientific notation, we multiply the coefficients and add the exponents:
Total energy generated in a year = 4 * 3.15 * 10^(26+7) joules
Simplifying the multiplication:
Total energy generated in a year = 12.6 * 10^(26+7) joules
Adding the exponents:
Total energy generated in a year = 12.6 * 10^33 joules
Expressing the answer in scientific notation:
Total energy generated in a year = 1.26 * 10^34 joules
Therefore, the sun generates approximately 1.26 * 10^34 joules of energy in a year.
The sun generates about 4 * 10 ^ 26 joules of energy every second. There are about 3.15 * 10 ^ 7 seconds in a year. 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) joules
