Answer» ONG>Answer:

Lete begin with no.15

a. To ever action there is an equal and opposite reaction

b. momentum is vector quantity unit is kgms

c. mass × VELOCITY. Force = rate of change of momentum

d. equal reaction but in opposite direction

total momentum REMAINS CONSTANT provided no external force acts

13. answer is 25×10N=250N

14. physical quantity is weight

12. is ACCELERATION is 10÷5=2

10 is false

no. 1 is Force

no.2 is that the rate of change of momentum is directly proportional to the applied force and takes place in direction of force

3. is the unit of force is a netwon

that's what I have answered
