Question

The sun generates about 4×1026 joules of energy every second. There are about 3.15×107 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)

Answer 1

thats wrong.

Answer 2

To find the total amount of energy generated by the sun in a year, we need to multiply the rate of energy generation per second by the number of seconds in a year.

The rate of energy generation per second is given as 4×10^26 joules.

The number of seconds in a year is given as 3.15×10^7 seconds.

Multiplying these two numbers gives us: (4×10^26) * (3.15×10^7) = 12.6×10^(26+7) = 12.6×10^33

Therefore, the sun generates about 12.6×10^33 joules of energy in a year.

Answer 3

Apologies for the incorrect response. Let's calculate the correct answer.

The sun generates about 4×10^26 joules of energy every second.

There are about 3.15×10^7 seconds in a year.

To find the total energy generated in a year, we need to multiply the rate of energy generation per second by the number of seconds in a year:

(4×10^26) * (3.15×10^7) = (4 × 3.15) × (10^26 × 10^7) = 12.6 × 10^(26+7) = 12.6 × 10^33.

Therefore, the sun generates about 1.26 × 10^34 joules of energy in a year.
