The equation you need to use is 
where Q is the charge in C, I is the current in Amps and T is the time in seconds.
So we have T = 60s
I =
A
let's work out Q
C
this is the total charge passing a point in a minute so divide by the charge of one electron (
) to find the number of electrons passing the point in a minute which equals 
So we have T = 60s
I =
let's work out Q
this is the total charge passing a point in a minute so divide by the charge of one electron (
Answer:
The value is
Explanation:
From the question we are told that
The velocity of the each of the three cars is
The velocity of the fourth car is
The initial velocity of the fifth car
Generally from the law of momentum conservation we have that
Given that the cars are identical then their mass will be the same
i.e
=>
=>
= >
