Points Calculate the capacitance of a system that stores 4.0 x 10-10 C of charge at
250.0 V. Use C =
AV
A. 1.0 x 107 F
B. 1.0 x 10-7F
C. 1.6 x 10-12 F
D. 6.2 x 1011 F

you have to draw the persons position over there

prolly a beacuse the momentuem the car has increases while going down hill

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
