Physics 2 incoming 14 hours

[Bill Nye No.6216430]

I need to study for my physics 2 exam incoming in 14 hours. I have until 8 am tomorow to learn these topics WHICH I DONT KNOW YET!!!

qvxB (Lorenz force) & Biot–Savart
Ampere's
Faraday's

also need to study on previous exam material, which i already did kind of study.

where the fuck do istart?

im on adderal

im on coffee

my body and brain is ready

You don't need pills nor coffee.

Lorentz force only demands you know vectorial multiplication and follow that correctly. F=q*(vxB) so for a line F=B*I*L, where I is current and L is the length of that line and L is ofc the perpendicular part of line lenght to B (mind the cross product)

Now Faraday's law is just induction of voltage from magnetic field. Take a path through a closed loop: the induced voltage all around that loop is the derivative of the flux inside. If you go through a loop several times, ilke in a coil, you multiply accordingly. Now the induced voltage or the integral of E*dl has to release somewhere and it does so at elements in that loop, be it open contact or a resistor. Just make sure you take the actual flux into consideration.

Now, ampere's law relates the path integral to the curent inside. This is also quite simple, especially if you work with H instead of B, since H has units A/m so it's integral over length has units A. The ampere's law is useful for determining the field around a wire. It may also be used to determine the field inside a transformer, since you can just take the path of integration along the length of the core.

>I don't think you can ace any exam in 8 hours learning, unless the school is shit easy, you can most probably pass no problem.

I'm taking this same test on Thursday anon. Its not hard. Stop being such a coon.
