gravity travels at the speed of light. so lets say the sun completely vanished mass and all, we would still orbit a full 8 minutes before we notice a thing.

my question is what the hell are we arguing about. venus is hotter.

here read the wiki article you might learn something

actually the temp between the light and dark side doesn't vary that much, its the upper atmosphere thats the cold part.http://en.wikipedia.org/wiki/Venus_(planet)

um isn't venus hotter than mercury?

its an acceleration?

check out this illusion, stand about 12 feet back and they will switch places

sorry about that. p.s. krz i forgot to add in the second it took for the officer to react.

i got 14.8 first i took 90km/h and 140km/h then converted them to m/s which comes out to be 25m/s and 38.9m/s respectively. we will call the car 25,x and car 38.9, z after this i use the equation d=Vot+.5at² where d=distance, Vo=original velocity, a=acceleration, t=time the first second for car x travels 25m, using d=25(1)+.5(0)(1²) the last part is zeroed out because there is no acceleration. car z travels 38.9m, d=38.9(1). we need to now make two equations involving car x and z that are set equal to each other,but we must also add in those other two answers in them. since they are going to be at an equal distance in a certain amount of time, we can do this 38.9t+38.9= 25+25t+.5(2)t² (btw we had to add the other values 38.9 and 25 into the equation) now get everything to one side -t²+13.9t+13.9=0 now just put the numbers into the quadratic formula then volia 14.8s i hoped that help explain, its hard to get these kinds of points across on the net.
