This are four different questions.
You purchased a new Indoor/Outdoor Extension Cord in Orange color (so you can cut the grass with your new electrical mower). This cord rated at 13 A. You plugged it to an outlet with 120 V. a) What must be the resistance of your cord, assuming the current is 13A? b) How much energy does it spend per second? c) if you decide to plug 3 of these cords (make it longer), what do you expect will happen to the resistance of the total length of the cord? If you were to measure the current now, do you expect it would still be 13A? Please only explain. you do not need to calculate values on this part c.
A light bulb has a resistance R=240. It is connected to a battery with DC voltage of 120V. a) How much current does the bulb draw? b) What is the power output for this lightbulb?
Imagine you are traveling by Gulf Shore, Alabama. You find on your radio device the radio station for NPR is: FM radio to 91.3 MHz (mega hertz = 100Hz or look at conversions). a) What kind of waves is your radio device receiving? (light, sound longitudinal, transverse...) Explain. b) What is the speed for theses waves? b) What is the frequency for these waves? c) What is their wavelength?
Calculate the electric force between two charges Q1=+6C and Q2= + 2C a) If the separation between the charges is d=200.0cm b) If the separation is d=2.0 m c) From your two answers above, when do the charges experience the strongest force? Is the force attractive of repulsive? EXPLAIN.
