From the rocket that was fired, same as any other rocket leaving earth.

but thats when something starts on earth and crashes into the earth, its different when its in orbit. Low earth orbitters need to travel heaps faster than geo stat to match their falling motion with the curve of the earth, uthawise they will crash into the earth

It says the rocket is fired forward that reduces its orbital speed, it says nothing about the speed it needs to get there just that it was fired in order to reduce obital speed. Therefore it must be A. Because geo-stationary satellites travel much slower than low earth orbitters

Yes a drive does go far but thats because its got lots of speed to get it far. The max range for any projectile will always be achieved if you fire it at an angle of 45. Also you cant compare those two actions because ur using two different clubs and its a totally different technique when...

I also think Q8 is C because even though batteries are DC when the switch turns on there will be a quick change in the magnetic field which will affect the galvanometer and then the current will subside after when the current is flowing and thhere is no more magnetic field Also another...

Nah, time differs for different angles because it goes higher in the sky and only gravity is what makes it fall. Go to this website: http://galileo.phys.virginia.edu/classes/109N/more_stuff/Applets/ProjectileMotion/jarapplet.html

Hey, wouldnt Q5 be C because the max range is 45 then the same range is achieved by angles that are complimentary. So shooting higher in the sky would make it stay up longer
