Homework Statement
A long wire carrying 6.50A of current makes two bends. The bent part of the wire passes through a uniform 0.280T magnetic field directed as shown in the figure and confined to a limited region of space.
Part A: Find the magnitude of the force that the magnetic field...

Homework Statement
Typical household currents are on the order of a few amperes.
If a 1.60A current flows through the leads of an electrical appliance, how many coulombs pass through it in 6.50min ?
Homework Equations
I=ΔQ/Δt
The Attempt at a Solution
6.50min=1min/60s= 0.108s...
after reviewing it I realize that the total momentum would zero. Because of the fact that only the masses are given and there's no other way to compute this.
Homework Statement
1) A 0.25kg book rest on a table. A downward force of 9.5 N is exerted on the top of the book by a hand pushing down on the book.
2)what is the size of the normal force exerted by the table on the book

that the final momentum will be given with their respected velocities.
0+0=52kgv1(final)+77kgv2(final). But I still don't see a way to solve this. Unless I factor the v(final)?
