A particle moves along a straight path with velocity v(t) = (4 - 4t) m/s at a time s. What is the total distance traveled by the particle from 0 sec to 4 secs

Given the electricity rate of 9.4 $ per kWh, how much will it cost in $ to accumulate 1 C of charge in a spherical capacitor with radius 0.7 m?

draw graphs of the voltage over r1 (v against t graph) for the charge cycle.  starting at t=0 until steady state after the switch is closed (initially all capacitors are empty) and another case when the switch is opened (initially the capacitors are fully charged)r1 = 100k ohms r2 = 10k ohms v1 = 5v (dc)  c1 = 100nf c2 = 220nf c3 = 330nf
