An uncharged capacitor and a resistor are connected in series to a source of emf. If e m f = 10.0 V, C = 18.0 µF, and R = 100 Ω, find the following: a. The time constant of the circuit.
b. The maximum charge on the capacitor.
c. The charge on the capacitor at a time equal to one time constant after the battery is connected.

Asled is being held at rest on a slope that makes an angle θ with the horizontal. after the sled is released, it slidesa distance d1 down the slope and then covers the distance d2 alongthe horizontal terrain before stopping. find the coefficient ofkinetic friction μk between the sled and the ground, assumingthat it is constant throughout the trip. find the coefficient of kinetic frictionμk. express your answer in terms of someor all of the variables d1, d2, and θ.
