When you push a door closed it doesn't travel in a straight line it turns around the hinges this is an example of a line
u = 0.077
Explanation:
Work done by friction is
Wf = ∆KE + ∆PE
-umgx = ∆KE,. ∆PE =0 (level ice surface)
-umgx = KEf - KEi = -(1/2)mv^2
Solving for u,
u = v^2/2gx
= (12 m/s)^2/2(9.8 m/s^2)(95 m)
= 0.077
Quantity of electrical charge is measured in Coulombs.
The symbol is C.
b. C
Answer:

Explanation:
The speed of the waves in a string is related with the tension and mass per unit length of the string, as follows:

First, we calculate the mass per unit length:

Now, we calculate the speed of the waves:
