In deep space, there is very little friction. once they launch a probe into deep space, where there are no external forces acting on it, scientists shut the probe’s engines off because the scientists want the probe to stop immediately. speed up. slow down. move at constant velocity.

In all trials, the magnitude of the final velocity for g1 + g2 was less than the magnitude of any initial velocity. as mass increased, what happened to the velocity? the velocity decreased. the velocity increased. the velocity of g1 + g2 could not be measured. the velocity was not affected by the mass increase.

Determine the age of a fossil if it had only one eighth of its original carbon-14 content remaining?

The necleus of an atom is made up of what subatomic particles?
