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.

a longitudinal wave moves energy that is to the direction of the wave’s movement. - true

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat
