Two coils are wound around the same cylindrical form. when the current in the first coil is decreasing at a rate of -0.250 a/s, the induced emf in the second coil has a magnitude of 1.65 x 10^-3 v. a) what is the mutual inductance of the pair of coils? b) if the second coil has 30 turns, what is the flux through each turn when the current in the first coil equals 1.25 a? c) if the current in the second coil increases at a rate of 0.3 a/s, what is the magnitude of the induced emf in the first coil?

Assume you measured the mass of the cart to be (500 ± 1) g and the mass of the additional mass you put on the cart to be (500 ± 1) g as well. since the scale you are using in the lab cannot measure objects heavier than 600g you will have to sum up individual pieces and propagate the error. so what would be the mass and the standard error of the cart and the mass
