It allows the current flowing through it to be controlled. It allows it to flow and it can prevent it from flowing. This saves electricity.
Answer:
750 kg.m/s
Explanation:
Momentum is the product of mass and velocity in kg.m/s.
In this case, initial momentum⇒p=m × v where m is mass and v is velocity
initial mass of car m₁=100 kg
Initial velocity of car v₁=5 m/s
Initial momentum= 100×5= 500 kg.m/s
New mass after picking two extra people m₂= 150 kg
Velocity stays the same v₂=v₁= 5 m/s
New momentum= m₂× v₂
p=150×5=750 kg.m/s
