The mass of teh hydrogen atom is 1837 times that of the electron. Assume that all motion, before and after the collision, occurs along the same straight line. What is the ratio of the kinetic energy of the hydrogen atom after the collision to that of the electron before the collision?

Could it be that the Universe is trapped in an infinate time-loop? Could it be that the Big Bang has happened (maybe multiple) times before?

Maybe every time the Universe collapses on itself it could be reborn with another Big Bang. Maybe when this happens everything happens over again. Ergo, it's possible we've lived these same lives before (maybe multiple times).

Is this possible?

A 5.0-kg Bucket of water is raised from a well by a rope. If the upward acceleration of the bucket is 3.0 m/s2(squared), find the force of excerted by the rope on the bucket.

If you could be so kind to show your work so i would understand i'd be very greatful

a) the force on the wagon is as strong as the force on the horse. The horse is joined to the Earth by flat hoofs, while the wagon is free to roll on its wheels.



b) The forse pulls before the wagon has time to react so they move forward.



c) The forse pulls forward slightly harder than the wagonpulls backward on the horse, so they move forward.



i thought this question was pretty weird. answer "a" makes sense in the first sentence, but the socond sentence of choice a screws the answer up. choice b does not make any sense. and i'm not sure bout choice c. Does this question make sense?

If a rocket from earth going to ..say Uranus..or other planet,...do they follow a linearly(straight) flight path or a curvy flight path?( of course after its leaving gravity),....i wonder wether actually space is not linear/plain..but wrap,..as theory of gravity.

does anyone know how to, or can explain how i can begin to solve this problem, An unknown mass is placed on one side of an Atwoods Machine. the downward acceleration of the mass 5 kg is observed to be exactly one-half of the acceleration due to gravity. Noting that the tension in the cord is the same on each side of the pulley, determine the tension force and the unknown mass.
