b). in only those domains where Newton's laws are valid
c). in all domains including domains where Newton's laws may not be valid
d). in only those domains where quantum laws are valid.​

Answer 1

Answer:

b

Explanation:

momentum explained by newton in his 2 law of motion

Answer 2

Answer : The validity of the conservation of momentum is b). in only those domains where Newton's laws are valid

Explanation:

• The law of conservation of momentum is based on Newton’s third law because the law of conservation of momentum can be derived from the law of action and reaction, which states that every force has a reciprocating equal and opposite force.
• The mass of the system must remain constant during the interaction. As the objects interact (apply forces on each other), they may transfer mass from one to another; but any mass one object gains is balanced by the loss of that mass from another. The total mass of the system of objects, therefore, remains unchanged as time passes

• The net external force on the system must be zero. As the objects collide, or explode, and move around, they exert forces on each other.

Hence, validity of the conservation of momentum is b). in only those domains where Newton's laws are valid.
