Using only astronomical data from the Appendix E in the textbook, calculate the speed of the planet Venus in its essentially circular orbit around the sun. Venus = 4.87x10^24

Explanation:

Given that,

Mass of Venus,

We know that,

Mass of Sun,

The distance between the center of Sun and the center of Venus is

We need to find the peed of the planet Venus in its essentially circular orbit around the sun. using the formula,

Put all the values,

So, the speed of the planet venus is .

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
