"Q = ΔU + W" is the equation is used to solve the questions related to "First law of thermodynamics".
<h3> What is the first law of thermodyanamics?</h3>
"First law of thermodynamics" states that "energy" neither created nor destroyed, but it can transfer from "one form of energy" to "another form of energy".
This "First law of thermodynamics" is also called as "law of conversation of energy". The formula for "First law of thermodynamics" of a system is that "change in internal energy of a system" is same as the difference of "heat energy" flows across the " boundaries of a system" and the "work done" on the system.
ΔU = Q - W
Q = ΔU + W
Where, "ΔU" is "change in internal energy", "Q" is "heat transferred and "W" is "work done.
Hence "Q = ΔU + W" is the equation is used to solve the questions related to "First law of thermodynamics".

Answer:
Option A
Explanation:
By law if conservation of momentum we know that the the initial and final momentum of a system remains conserved . Therefore the final momentum of system will be 400 kg -m/s
<u>Proof</u><u> </u><u>:</u><u>-</u>
Let the final momentum of car be " x " .
By Law of conservation of momentum ,
→ m1 u1 + m2 u2 = m1 v1 + m2 v2
→ 400 kg m/s + 0 = 500 kg - m/s + x
→ x = 400 - 500 kg m/s
→ x = -100 kg - m/s
Combined momentum = -100 + 500 = 400 kg-m/s
