A 12.5μF capacitor is charged to a potential of 50.0V and then
discharged through a 75 Ω resistor.Show all work without
skipping any steps. Use a pen and paper or an equation editor only.
Thanks!
a)How long after the discharge begins does the charge drop to
90% of its initial value?
b)What is the current through the capacitor at this time?
c)What is the time constant for this circuit?

An infinitely long line of charge has linear charge density
4.00×10^−12 C/m. A proton (mass 1.67×10^−27kg, charge +1.60×10^−19
C) is 18.0 cm from the line and moving directly toward the line at
3.80×10^3 m/s. How close does the proton get to the line of charge?
Please show all steps CLEARLY so I can follow and understand how to
derive the equation and solve for the answer with my given values.
Thank you so much in advance!!!

How do you calculate the Resistance of a Solenoid with
permeability is only air and the Resistivity is copper? Please show
me some equations and relationships. I just need variable
relationships. no numbers just physics! Thank you!

A parallel-plate capacitor has circular plates and no dielectric
between the plates. Each plate has a radius equal to 2.2 cm and the
plates are separated by 1.1 mm. Charge is flowing onto the upper
plate (and off the lower plate) at a rate of 2.9 A. (a) Find the
rate of change of the electric field strength in the region between
the plates. V/m·s (b) Compute the displacement current between the
plates and show that it equals 2.9 A....

Show all work and diagrams necessary. Please make sure
you show how you derive any equations you used!!!
An initially resting 422 g car is dragged along a horizontal
frictionless table by a massless cord. The cord is attached to a
vertically hanging unknown mass by a frictionless massless pulley.
Given that the car starts from rest, and moves 41 cm in 3.0 s,
determine the unknown mass. Please give your solution in grams.

A 50-turn square coil with a cross-sectional area of 5.00 cm2
has a resistance of 30.0 Ω. The plane of the coil is perpendicular
to a uniform magnetic field of 1.00 T. The coil is suddenly rotated
about the axis shown in the figure below through an angle of 60∘
over a period of 0.200 s. Use a pen and paper or an
equation editor only to solve the problem. Please show all work
clearly without skipping any steps.
