When this happens the inward force of gravity is exactly balanced with the outward force created by and . i believe this question is about nuclear fusion

Ineed ! i have no clue how to do this problem.

Movement that is like a t a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. transfers energy from one location to another a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave

Give one example of a pure (exact) number and of an estimated (measured) number.
