I know I(t) = Io [1 - e-t/t ] is the formula to calculate the current in an RL circuit, however i have no clue what "e" stands for. Can someone give me an insight?
Homework Statement

Two capacitors when connected in parallel give an equivalent capacitance of 9.00 pF and an equivalent capacitance of 1.55 pF when connected in series. What is the capacitance of each capacitor?
in parallel:
C1 + C2 = 9.00 pF
in series:
(1/C1) + (1/C2) = (1/1.55pF)
My attempt:
(C1 +...
According to its design specification, the timer circuit delaying the closing of an elevator door is to have a capacitance of 33.0 µF between two points A and B.
(a) When one circuit is being constructed, the inexpensive but durable capacitor installed between these two points is...
A transverse wave on a string is described by the following wave function.
y = (0.100 m) sin [(x/11 + 3t)]
(a) Determine the transverse speed and acceleration at t = 0.150 s for the point on the string located at x = 1.60 m.

You are given that the coefficient of kinetic friction between the block and the table in the figure is 0.560, and m1 = 0.150 kg and m2 = 0.250 kg.
(a) What should m3 be if the system is to move with a constant speed?
this is what i have:
T2 - T1 - f = m3a
m2g - m1g - ukg = m3
