In 1984 by George Orwell, what do the 3 slogans (war is peace, ignorance is strength, freedom is slavery) mean? I would like to know what EACH suggests about the society. And how is the society able to get people to accept them as logical. I was thinking that they chose contra...

Can anyone help with this...I need to find the derivative of the functions below. If possible please show working so I can try and understand? f(t) =3-t^4 and g(t)=sin(4t) Then using the Quotient Rule differentiate the function k(t) 3-t^4/ sin(4t) (0<t< pie)

Physics
Hey, I thought about it a little more and I have your answer here. B = mu(naught) * I / (2pi * r) You can solve for I in that equation. I hope it looks familiar. mu(naught) = vacuum permeability I = current r = radius of wire

Physics
I won't be able to answer exactly, but we know that the net force on the wire would be zero. So it means that Force(gravity) = Force(magnetic)
