Additional capacitor do you need to produce a capacitance
You need a capacitance of 40 µF but you don't happen to have a 40 µF capacitor. You do have a 56 µF capacitor. What additional capacitor do you need to produce a total capacitance of 40 µF?

Suppose three point charges are arranged as shown in the figure below. A charge q1 = +1.5 µC is located at the origin of an x-, y-coordinate system; a second charge q2 = -0.64 µC is located at (1.20 m, 0.50 m) and the third charge q3 =
a) If the velocity of a pitched ball has a magnitude of 50.0 m/s and the batted ball's velocity is 60.0 m/s in the opposite direction, find the magnitude of the change in momentum of the ball. b) Find the magnitude of the impulse applied to it by
A fighter jet lands on the deck of an aircraft carrier. It touches down with a speed of 73.5 m/s and comes to a complete stop over a distance of 194.8 m. If this process happens with constant deceleration, what is the speed of the jet 31.5 m befor
You then stand, elevating your eyes by a height H = 1.70m, and stop the watch when the top of the Sun again disappears. If the elapsed time is t = 11.1 s, what is the radius r of Earth?
Macrophages are cells referred to as "big eaters" or "killing machines" that destroy any foreign agents (pathogens) or antibodies found in the body.
Find the tangential and centripetal acceleration at the top of the loop using the velocity from part A.
When a current of I = 22 A exists in the wire, the wire swings upward and, at equilibrium, makes an angle with respect to the vertical, as the drawing shows. Find (a) the angle and (b) the tension in each of the two strings.
