Power = (current) x (voltage) .
Answer:
False
Explanation:
Density is more of a physical property
Answer:
Explanation:
It is given that,
The angle of the hill is 6.00° with respect to the horizontal. Let is the coefficient of kinetic friction between the surface of the hill and the toboggan.
A toboggan slides down a hill and has a constant velocity. On an inclined plane, force of friction will also act.
Force of friction, ...........(1)
Normal force, ............(2)
From equation (1) and (2) :
So, the coefficient of kinetic friction between the surface of the hill and the toboggan is 0.14. Hence, this is the required solution.
Answer:
When two objects in motion hit each other they experience forces that are equal in magnitude and opposite in direction. This force causes one of the objects to speed up or gain momentum and other to slow down or lose momentum.
We have: A= F.s
So, A = 22 x 16
A= 352J
Só A is correct answer
