its velocity is 51, or 51.42 to be exact it would be: 51.4285714286
I know one is transformed, not sure about another
Just because the book is moving doesn't tell you anything about the forces on it, or even whether there ARE any.

Took the quiz and got it right
Answer:
2.1 column, 1.31×10^19 electrons
Explanation:
Now Charge, Q = current × time
=0.028×75=2.1columb
2. Now the charge of 1 electron is 1.6×10^-19C
Hence for 2.1 C, the number of electron is;
2.1/1.6×10^-19 = 1.31×10^19 electrons
