<u>Answer:</u>
The final velocity of the two railroad cars is 1.09 m/s
<u>Explanation:</u>
Since we are given that the two cars lock together it shows that the collision is inelastic in nature. The final velocity due to inelastic collision is given by
where
V= Final velocity
M1= mass of the first object in kgs = 12000
M2= mas of the second object in kgs = 10000
V1= initial velocity of the first object in m/s = 2m/s
V2= initial velocity of the second object in m/s = 0 (given at rest)
Substituting the given values in the formula we get
V = 2×12000 + 0x100012000 + 10000= 2400022000= 1.09 m/s
Which is the final velocity of the two railroad cars

Answer:
Making a Hypothesis
Explanation:
-Research the subject of your question. Review the literature and find out as much as you can about previous information and discoveries surrounding your question.
-Develop an educated guess that answers your initial question. This is your hypothesis. Make a prediction based on your hypothesis and state it as a cause-effect relationship.
Explanation:
Given that,
Distance between two long wires, d = 16 cm = 0.16 m
Current in one wire, 
Current in wire 2, 
The magnetic force per unit length of one wire on the other is given by the following expression as :
The current is flowing in opposite direction, the magnetic force acting on it is repulsive. Hence, this is the required solution.
