Define probes.

A space probe is traveling in outer space with a momentum that has a magnitude of 7.5 xx 10^7 kg-m/s. A retrorocket is fired to slow down the probe. It applies a force to the probe that has a magnitude of 2.0 xx 10^6 N and a direction opposite to the probe's motion. It fires for a period of 12 s. Determine the momentum of the probe after the retrorocket ceases to fire.

Assertion A genetic probe is helpful in the detection of specific DNA sequence. Reason Genetic probe is a radiolabelled cDNA, which has complementary base sequence, to DNA fragment which is to be detected.

A 5.0xx10^(4) kg space probe is traveling at a speed of 11000 m/s through deep space. Auxiliary rockets are fired along the line of motion of reduce the probe's speed. The auxiliary rockets generate a force of 4.0xx10^(5)N over a distance of 2500 km. What is the final speed of the probe ?
