This is not an essay question, im trying to figure out how to solve for the solutions.
Question 1: A) Dinesh studying rail guns has been suggested for launching projectiles into space without chemical rockets. A tabletop model rail gun (Figure 1.) consists of two long, parallel, horizontal rails, l= 6.80 cm apart, bridged by a bar of mass m= 8.00 g that is free to slide without friction. The rails and bar have low electric resistance, and the current is limited to a constant I = 42.0 A by a power supply that is far to the left of the figure, so it has no magnetic effect on the bar. Figure 1 shows the bar at rest at the midpoint of the rails at the moment the current is established. He wishes to find the speed with which the bar leaves the rails after being released from the midpoint of the rails (Hint: you need to draw the figure). (Mo = 4π × 10-¹T.) Jg x V₁ = = 0 m d Figure 1. (i) Find the magnitude of the magnetic field at a distance of 1.85 cm from a single long wire carrying a current of 2.40 A. (ii) For purposes of evaluating the magnetic field, model the rails as…
The capacitor in the circuit shown below is initially uncharged. The switch is closed at t = 0 s. AV battery = 30 V, C = 3.0 F, and R = 2.0 2. At sometime after the switch is closed, the current in the circuit is measured to be 9.3 A. What is the charge on the capacitor at this time, in Coulomb? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.

A current I = 3 A is passed through a wire. A second wire of length L = 1 m is moving with velocity v= 285.4 m s¨¹ at a distance d=1 cm perpendicular to the magnetic field generated by the first wire (see sketch below). Calculate the current in the circuit that includes the second wire and a stationary piece of wire (green in the sketch below). Take the resistance in the circuit to be 10 Q2 (Ohm). Consider the magnetic field B to be constant over the range of motion of the second wire (i.e. d » 1 ). For the permeability of vacuum take μo = 1.3×10-6 NA².

Given: B = 5 * 10-5 T ẑ; σ = 4 (Ohm-meters)-1 (conductivity) a) Assume that seawater is moving at a constant velocity v = v0 ŷ and that the Earth’s magnetic field is along the ẑ-direction. Calculate the electric current density J produced by the magnetic force. Hint: first compute the force per unit charge, F/q, and then use the relationship J = σ(F/q). b) Derive the equation of motion of a cylindrical differential volume element of base area δA and height δh parallelto the direction of J. Assume that seawater has a known volumetric mass density ρ. Show that this equation implies that the velocity satisfies the following differential equation:dvy/dt = vy/τwhere τ is a constant that you should write in terms of B, σ, and ρ.
Draw a sketch of the situation in the figure, showing the direction of electrons carrying the current, and use RHR-1 to verify the direction of the force on the wire.
