Body A comes to the rest as this criteria can only conserve the momentum .. keep one thing in mind velocities get exchanged when there is a perfect elastic collision that to the masses have to be same

Answer:

Body A comes to rest.

Explanation:

If two objects collide and one of them was at rest and have the same mass, what will happen is that the one that was at rest will absorbe the kinetic energy of the system, and start moving with the same initial velocity of Body A.

The mixture you separated was a mixture of iron filings, sand, and salt. Based on your understanding of matter, is this mixture
V125BC [204]

Answer: Heterogeneous mixture - the parts are not uniformly mixed.

A mixture contains components having distinct chemical properties. There are two types of mixtures: homogeneous and heterogeneous. In a homogeneous mixture there is uniform distribution of components. we cannot distinguish one portion of the mixture from another. for example salt mixed in water. In heterogeneous mixture, the components are not uniformly mixed. hence, we are able to distinguish different parts of a mixture, like the mixture of iron, sand and salt given in this question.

A water bottle is dropped from a plane and accelerates because of gravity. What distance did it fall during 3 seconds?
exis [7]
It’d fall 29.4m or 96.46ft

Explanation:
Uhh since gravity is 9.8m/s then in three seconds it’d drop 29.4m or 96.46ft
That is assuming there isn’t a lot of wind resistance, but if you take that into account, then it’d probably be somewhere around 25m since the water bottle is going to be heavier than the wind resistance, and since we don’t know the weight of the water bottle it can’t really be calculated.

Hope this helps!
