Hello. You did not enter the data to which this question refers, which makes it impossible for it to have an exact answer. However, I will try to help you in the best possible way.
The forces that hold the elements together are called intermolecular forces. They are formed by covalent bonds between the molecules and can be called: dipole-induced (occurs between nonpolar molecules that have a negative pole and a positive pole) and dipole-dipole (occurs between polar moileculas, except when hydrogen is present).
The velocity of Satellite A is 2% greater than velocity of satellite B.
The given parameters;
- <em>Altitude of Satellite A = 500 km</em>
- <em>Altitude of Satellite B = 800 km</em>
The forces acting on the Satellites are given as follows;


Thus, the velocity of Satellite A is 2% greater than velocity of satellite B.

A is false because light and sound waves can both reflect off of objects
Objects in space follow the laws or rules of physics, just like objects on Earth do. Things in space have inertia. That is, they travel in a straight line unless there is a force that makes them stop or change. The movement of things in space is influenced by gravity.
