Chapter 44, Problem 26P

Can someone help me with this thank you

(a) For a spherical capacitor with inner radius a and outer radius b, we have the following for the capacitance. ab C = k₂(b- a) 0.0695 m 0.145 m (8.99 × 10º N · m²/c²)( [0.145 m- 0.0695 m × 10-11 F = PF II

A pendulum bob A (0.5 kg) is given an initialspeed of vA = 4 m/s when the chord ishorizontal. It then hits a stationary block B (1kg) which then slides to a maximum distanced before it stops. Determine the value of d.The coefficient of static friction between theblock and the plane is μk = 0.2. The coefficientof restitution between A and B is e = 0.8.Ans: d=1.0034 m

Figure 29-43 Problem 12. ••13 In Fig. 29-44, point P₁ is at distance R = 13.1 cm on the perpendicular bisector of a straight wire of length L = 18.0 cm carrying current i = 58.2 mA. (Note that the wire is not long.) What is the magnitude of the magnetic field at P₁ due to i? P2° R R L

Checkpoint 1 The figure shows the current i in a single-loop circuit with a battery B and a resistance R (and wires of neg- ligible resistance). (a) Should the emf arrow at B be drawn pointing leftward or rightward? At points a, B C R b, and c, rank (b) the magnitude of the current, (c) the electric potential, and (d) the electric potential energy of the charge carriers, greatest first.

16. Anita and Betty compete in the hammer throw. Anita can spin the hammer three times as fast as Betty. Compare the magnitudes of the two centripetal accelerations for the two hammers. Justify your response.
