ASTRONOMY HELP :
5. (T or F) Flux is not related to the distance from the source.

4. (T or F) A G star is hotter than an M star.

3. (T or F) Parallax is a good method to find the distance to a star say 1300 LY away.

Could someone . i have tried to solve myself but my calculation is off

Acombination reaction is when two or more combine to form one product. a decomposition reaction is when a substance breaks down into two or more simpler substances in a chemical reaction.

The astronauts on the space shuttle flights experienced an acceleration of 29 m/s2 (about 3 "g's") during lift-off. what upward force must the astronaut's seat apply to the astronaut in order to cause this acceleration? assume the astronaut's mass is 70 kg, and compute this force when the acceleration is near the earth's surface so their weight equals latex: mg m g .
