What is the surface gravity of earth and the moon?

The Earths' gravity is what we base our calculations on. 1G. Standard gravity. 9.81 meters/sec^2 as you head towards the Earths' center. The moon has 1/6th of that.

How long does sunlight take to reach earth?

This varies with the Earth's distance from the Sun, but it takes the light from the Sun between 8 and 8 1/2 minutes to reach the Earth.
