PLEASE HELP, OVERDUE ASSIGNMENT!!

Cassy shoots a large marble (Marble A, mass: 0.06 kg) at a smaller marble (Marble B, mass: 0.03 kg) that is sitting still. Marble A was initially moving at a velocity of 0.7 m/s, but after the collision it has a velocity of −0.2 m/s. What is the resulting velocity of marble B after the collision? Be sure to show your work for solving this problem along with the final answer.
I need help because this doesn't make sense to me!! -O-
Please explain in not-gibberishhh! TvT
(It's not multiple choice)

Answer 1

Answer:We can solve this using the Law of Conservation of Momentum. If both marbles are in our system, the initial momentum should equal the final momentum.

The initial momentum can be solved for as so:

*  +  =

(0.06)(0.7) + (0.03)(0) = 0.042 [kg * m/s]

So if the system has an initial momentum of 0.042, it should have the same final momentum.

(0.06)(-0.2) + (0.03)() = 0.042

(0.03)() = 0.54

() = 18 [m/s]

Answer: C. Touching a stove and burning your hand

A heater in a fish tank warming the water at the bottom of the tank is an example of convection.

What is convection of heat?

Heat is transferred through convection, which is the large-scale movement of molecules inside gases and liquids. Conduction is used to move heat from the object to the fluid initially, but fluid motion is responsible for the bulk of the heat transfer.

Convection is the process by which heat is transferred through fluids as a result of material motion.It occurs in both gases and liquids.It could be forced or natural.Bulk transfers of some of the fluid are necessary.

Hence,  a heater in a fish tank warming the water at the bottom of the tank is an example of convection.
