The circuit drawing is already given in the problem introduction. However, you can redraw this circuit to make it easier to reduce to a circuit with a single equivalent resistor. Which of the following circuits is equivalent to the circuit given in the problem? Resistor Circuits Learning Goal: To practice Problem-Solving Strategy 28.1 for resistor circuit problems. R4 Find the currents through each resistor in the circuit shown on the diagram (Figure 1). Use the following values: = 12.0 V , Ri-35.0 Ω , R2 = 22.0 Ω , R3 = 41.0 Ω , and R4 = 14.0 Ω Figure 1 of1 R3 R4 O R2

The lights used by mark watley (played by matt damon) during the film the martian seem to be metal halide lamps. metal halide lamps are filled with vaporized mercury and metal-halogen compounds. when an electric current is passed through the lamp, the tube begins to glow a bright white/blue color. if you were to pass this light through a prism to separate the individual light frequencies, you would see a rainbow just as you would if using natural sunlight because of the complexity of the metal halide gas and the vast amount of possible electron transitions. (the study of light in this way is known as spectroscopy and allows astronomers to know exactly what atoms compose distant stars, simply by looking at the light they emit. the spectral lines an atom produces uniquely identifies that atom just like a fingerprint uniquely identifies a person. the momentum equation and energy equation that we have used above can be combined to give the following equation: c = e p where again p is the phonon momentum, e is the photon energy and c is the speed of light. when you divide the photon energy found in #6 by the photon momentum found in #4, do you get the speed of light? (if not, check your work for questions #4 through #6). yes no
