Estimate how much mass the sun loses through fusion reactions during its 10-billion-year life. you can simplify the problem by assuming the sun’s energy output remains constant.

kg

Explanation:

The sun's energy output per second is 4.26 million metric tons, this is a constant value.

To solve for the amount of mass the sun loses during its 10 billion year life, multiply the energy output per second by the total time (in seconds) for the 10 billion year period.

CALCULATION

Mass loss = kg

earth's neighboring galaxy, the andromeda galaxy, is a distance of 2.54×107 light-years from earth. if the lifetime of a human is taken to be 70.0 years, a spaceship would need to achieve some minimum speed min to deliver a living human being to this galaxy.
