Why is the light intensity of one car headlight independent of the other? it depends on...
Your car's 28.5 W headlight and 2.10 kW starter are ordinarily connected in parallel in a 12.0 V system. What power (in W) would one headlight and the starter consume if connected in series to a 12.0 V battery? (Neglect any other resistance in the circuit and any change in resistance in the two devices. Answer to the nearest 0.1 W.) ___W
How do you know that homes are not wired in series?Are the two headlights of a car in series or parallel?Are fuses put in parallel or in series with devices they are meant to protect? Why is it unsafe to replace a fuse that keeps burning out with one which has a higher amp rating?A bulb and pair of batteries might have the batteries connected to each other in series or parallel. What are the advantages of each arrangement?
6. a. (4) Unpolarized light of intensity 100w/m? at point "A" traveling through air (index one) en- counters a planar junction with plastic of index of refraction 1.4 at an angle θ such that the reflected light is completely plane-polarized. What is the numerical value of θ? b. (4) What is the polarization unit vector of the reflected light at "B"? Circle the vector on the figure and give a formula for it in terms of i,j,k and anything else...
The intensity of a light source at a distance is directly proportional to the strength of the source and inversely proportional to the square of the distance from the source. Two light sources, one five times as strong as the other, are 9 m apart. At what point on the line segment joining the sources is the intensity the weakest? Write an equation representing the intensity, I, at a distance, x, from the weaker lightbulb, and with k as the...
Compare a 24-volt battery that is connected to four 25-watt light bulbs in parallel vs one that is connected in series. For both connections: a. Draw a diagram of these circuits. b. Find the voltage across each light bulb. c. Find the current in each light bulb. d. Find the resistance in each light bulb.
1.) In a CMOS NAND gate, if only one PMOS is ON, the output is low voltage (logic 0) High voltage (logic high) depends on the state of NMOS none of the other choices 2.) An NMOS with the drain connected to a 10V and source connected to ground can be turned on by applying a gate to source voltage of VGS= 0V VGS= 10V VGS= -10V None of the other choices. 3.) For the operation of enhancement type n...
2 Two linear polarizing filters are placed one behind the other, so that their transmission directions are parallel to one another. A beam of unpolarized light of intensity I_0 is directed at the two filters. What fraction of the light will pass through both filters?
Write neat please. Show step by step please. Read instructions carefully. do all problems please. double check your work. Box in answer please. Thank you Question 33 1 pts A 60-W light bulb and a 100-W light bulb are each connected to separate 120 V outlet. Which light bulb has more current in it? Both have the same current. O The 100-W bulb. O The 60-W bulb. Question 34 1 pts Two lamps, one with a thick filament and one...
At the race track, one race car starts its engine with a resulting intensity level of 108.6 dB at point P. Then 4 more cars start their engines. If the other 4 cars each produce the same intensity level at point P as the first car, what is the new intensity level with all 5 cars running?
If two light bulbs are set up in parallel and one in series as shown in the circuit above which bulb would be the brightest and why? Figure 2 Series and parallel combined
