With the battery voltage set to 15 volts, measure the current in a parallel circuit with 1, 2, 3, and 4 light bulbs. (In each case, place the ammeter next to the battery.) Use Ohm’s law to calculate the total resistance of the circuit. Record results below. Number of light bulbs 1 2 3 4
Voltage 15 volts 15 volts 15 volts 15 volts
Current 1. 3. 5. 7.
Total resistance 2. 4. 6. 8.

Which statement is true for light passing into a medium that is more optically dense than the first medium through which it past

High schoolphysics 5+3 pts a neon light consists of a glass tube with metal wires at each end. when connected to a high-voltage source, the gas glows. if a fly lands on the glass tube, what will most likely happen? a) the fly will not feel a shock because the glass conducts any free electrons back into the gas. b) electrons will flow directly from the metal wires along the glass and shock the fly. c) the fly will not feel a shock because the glass insulates it from the electrons in the gas and the metal. d) electrons that are moving through the gas will be conducted through the glass and shock the fly.

The slope of a velocity time graph over any interval of time gives the during that interval
