Chapter 20, Problem 10CQ

The switch S in Figure 20.27 is closed at t = 0 and the current at a reference time t_ref> 0 is I_ref. If the circuit is changed as, described below and the switch is again dosed at t = 0, determine whether the current I at the same time would be greater than, less than, or equal to the original value of I_ref. Indicate your answers wilt G. L. or E, respectively. (a) Both the battery voltage ε and the resistance R are doubled. (b) The inductance L b doubled. (c) The battery voltage ε. the resistance R, and the inductance L are each doubled.

Chapter 20, Problem 10CQ, The switch S in Figure 20.27 is closed at t = 0 and the current at a reference time tref 0 is Iref.

Figure 20.27 A series RL circuit. As the current increases toward its maximum value, the inductor produces an emf that opposes the increasing current.

Part C Find the height yi from which the rock was launched. Express your answer in meters to three significant figures. Learning Goal: To practice Problem-Solving Strategy 4.1 for projectile motion problems. A rock thrown with speed 12.0 m/s and launch angle 30.0 ∘ (above the horizontal) travels a horizontal distance of d = 19.0 m before hitting the ground. From what height was the rock thrown? Use the value g = 9.800 m/s2 for the free-fall acceleration. PROBLEM-SOLVING STRATEGY 4.1 Projectile motion problems MODEL: Is it reasonable to ignore air resistance? If so, use the projectile motion model. VISUALIZE: Establish a coordinate system with the x-axis horizontal and the y-axis vertical. Define symbols and identify what the problem is trying to find. For a launch at angle θ, the initial velocity components are vix=v0cosθ and viy=v0sinθ. SOLVE: The acceleration is known: ax=0 and ay=−g. Thus, the problem becomes one of…
