1.What is the weight of a 10.0 kg object situated at the top of mount everest, 8848 meters above earths surface?
Given: radius of earth 6380 km. mass of earth = 5.98x10^24 kg.
1. The average orbital distance of Mars is 1.52 times the average orbital
distance of the Earth. Knowing that the Earth orbits the sun in approximately
365 days, use Kepler's law of harmonies to predict the time for Mars to orbit the sun.
1) The average distance from the moon to the earth is 385,200 km. Convert this distance to miles by multiplying by 0.6 miles/km. This is the radius of the moon’s orbit.
