Chapter 26, Problem 26.15E

In the circuit of Fig. E26.15, each resistor represents a light bulb. Let R₁, = R₂ = R₃ = R₄ = 4.50 Ω and ε = 9.00 V. (a) Find the current in each bulb, (b) Find the power dissipated in each bulb. Which bulb or bulbs glow the brightest? (c) Bulb R₄ is now removed from the circuit, leaving a break in the wire at its position. Now what is the current in each of the remaining bulbs R₁, R₂, and R₃? (d) With bulb R₄ removed, what is the power dissipated in each of the remaining bulbs? (c) Which light bulb(s) glow brighter as a result of removing R₄? Which bulb(s) glow less brightly? Discuss why there are different effects on different bulbs.

Car P moves to the west with constant speed v0 along a straight road. Car Q starts from rest at instant 1, and moves to the west with increasing speed. At instant 5, car Q has speed w0 relative to the road (w0 < v0). Instants 1-5 are separated by equal time intervals. At instant 3, cars P and Q are adjacent to one another (i.e., they have the same position). In the reference frame o f the road, at instant 3 i s the speed o f car Q greater than, less than, or equal to the speed of car P? Explain.
