A. The coldEST regions in all of space is -270 Celcius (..-454 Fahrenheit..) This is about 2.728 degrees above absolute zero and is the universal temperature left over from the immense temperature of the Big Bang.

If you were in a spacesuit in deep space, would smaller objects orbit around you?
Q. Like a rock or a wrench? Maybe you couldn't just let go of a rock and it would orbit you, but what if it passed you going slowly enough, would it begin to orbit you, or does orbiting require a larger discrepancy in mass, so then my question is, would dust orbit you in deep space? Theoretically of course, I realize you'd die in space sooner or later. By mentioning "deep space" I'm implying there are no more massive objects anywhere nearby.

A. M = 79.237 kg G = 6.67428e-11 m^3 kg^-1 sec^-2 R = 1 meter P = sqrt { 4 ^2 R^3 / (GM) } P = 86400 sec = 1 day A man who would weigh 175 pounds on Earth could be, in deep space, the primary for a marble at a distance of 9 meters making one orbit around him in 27 days.

a) during a maneuver in deep space, a rocket experiences an acceleration?
Q. during a maneuver in deep space, a rocket experiences an acceleration s"(t)= 120ft/sec^2 for a period of 60sec. Initial velocity is s'(0)=100ft/sec a)what is the final velocity? b)assuming the initial position s(0)=0, how far does the rocket travel during this time? -find explicit formula for s't and s(t). c)what is the average velocity over these 60sec? d)compare the average velocity over the final 1sec of this manevuer and the final instant velocity. explain why they're almost the same?

A. Final velocity = Initial velocity + (Acceleration)x(time delta) Final velocity = 100 fps + (120 fps^2)x(60 sec) Final velocity = 100 fps + 7200 fps Final velocity = 7300 fps Rocket travels: You need to know average velocity first. average velocity = {initial velocity + final velocity}/2 average velocity = {100 + 7300}/2 average velocity = 3700 fps Rocket travels: 3700 fps x 60 sec = 222000 feet look at the link for formulas... To answer d: You need to know velocity at the 59th second: 59th sec velocity = initial velocity + (acceleration)x(59 sec) 59th sec velocity = 100 + (120 fps^2)x(59) 59th sec velocity = 100 + 7080 59th sec velocity = 7180 fps velocity at 60 sec = 7300 fps velocity at 59 sec = 7180. If you remove the initial… [cont.]
