Arussian cosmonaut(87 kg) and usa astronaut(94 kg) are outside the iss and decide to run a momentum experiment. they are motionless facing each other palm to palm, then push apart from each other. what happens to their momentum? a. their total momentum doublesb. their total momentum decreasesc. the guy with the smaller mass has less momentumd. their momenta are opposite but equal

their momenta are opposite but equal

Explanation:

Given are masses of a Russian cosmonaut and a USA astronaut in the sequence,

They are motionless initially and floating in the space without any friction.

According to the law of conservation of linear momentum of this system the sum of initial momentum will be equal to the sum of final momentum of the bodies.

Mathematically:

∵since the bodies are initially at rest.

where the negative sign denotes the opposite direction.

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

wire in brush may conduct electricity from cell to drill and vice versa electrc shock possible
