I think that it is false. You cannot exert force directly on an object without the object exerting a force on you. Newton has a law that states that for every action there is a reaction.This means that if you exert a force on an object it will do same but in the opposite direction of your force.
Answer:
Explanation:
Assuming that cars 4 and 5 have same mass so that the momentum
P=mv where m is mass and v is velocity hence
Momentum=0+2mv+3mv=5mv
The final mass is 2m+3m=5m
From aw of conservation of momentum
hence
Therefore, the speed is
I believe it’s 2020m? I’m sorry if it’s wrong
Electromagnetic waves can travel through a vacuum; mechanical waves require a medium.
No,the poping of microvave is not same there time is different
