Explanation:
Answer;
1 second
Explanation;
Two objects moving at the same speed will always stay the same distance apart. If two objects are moving at different speeds, the distance between them must change.
Therefore; if the distance will be the same and the speed is also the same then the time taken will be the same.
Answer:
Due to the fact that the comb is in terms of mass bigger than pieces of paper
Explanation:
In terms of mass, the comb is way too bigger than the piece of paper so it is virtually impossible for it to move towards the pieces of paper
According to Newton third law action and reaction are equal and opposite
Mathematically
P=m*v
Where
P= impulse is Newton
m=mass of the body
V= velocity of the body
Now since the comb has a greater mass it will not move to the paper, else the paper must have to move to it.
