1. The main component of gravity that determine the strength of the force are
a) The amount of Jedi Knights on the surface of the planets
b) The absolute lack of a sense of humor.
These two factors combine to determine the force of gravity
2. The ambulance sound louder as it comes towards you because ithe siren is trying
to get your attention. Once it's passed you, it doesn't care if you are listening to it
any more.
I am a rocket scientist and will be glad to give you all the answers you need so you won't have to bother to look it up and learn something.
Need help with few more questions for my science homework!!!

1. planets are held in orbit around the sun by gravity. name the 2 factors that determine the strength of the gravitational force.
2. why do you hear a higher pitched sound when an ambulance is moving toward you and a lower pitched sound when an ambulance is moving away from you than you would if you and the ambulance were both at rest?
3. list the regions of the electromagnetic spectrum in order of increasing energy.

how bout the third one
3. The regions of the electromagnetic spectrum are from the short end, mini-microwaves (in which you can only pop one kernel at a time) at the electric end to the long end, which include large alnico magnets that once placed on your refrigerator door, will never come off.
