Explanation:
Momentum is conserved in the collision. Momentum is conserved for any interaction between two objects occurring in an isolated system.
Answer:
Surface area of the dog is changes from A to 3A
Explanation:
It is given that surface area of dog is increased by factor 3 in a period of 4 year
We have to find the change in dog's relative surface area in the given time period
Let initially the surface area is A
As the surface area is increased by a factor of 3
So surface area after 4 year = 3×A = 3A
So surface area of the dog is changes from A to 3A
Explanation:
the work a force does is measured in newton-meters (N-m), which use the symbol of J. Time (t) is expressed in Second. Power (P) is expressed in Watt (W).
