- 1. A student connects four lamps A, B, C and D in the circuit shown in Figure 1. The battery has an emf of 9.0 mathrm(~V) and negligible internal resistance. Figure 1 (a) The table shows the operating conditions for the lamps when they are at normal brightness. Lamps & Operating voltage mathrm(V) & Power mathrm(W) A and C & 6.0 & 6.0 B and D & 3.5 & 4.1 The student observes that two of the lamps are at their normal brightness. Assume that any changes in resistance of the lamps are negligible. Determine which two lamps are at their normal brightness. Use calculations to support your answer. (b) The student connects another lamp mathbf(E) in the circuit as shown in Figure 2. Lamp mathbf(E) is identical to lamps mathbf(A) and mathbf(C) . Figure 2

- While individual objects may change their momentum during a collision, the overall or total momentum of the colliding objects is conserved. In any collision, the colliding objects will experience equal (and opposite) momentum changes, provided that the collision occurs in an isolated system. While individual objects may change their velocity during a collision, the overall or total velocity of the colliding square square FALSE square square square
