1 Two cells are connected in parallel by joining the terminals together so that they both face in the same direction. One of the cells has emf 6.0 V and internal resistance 3.0 Ω, and the other cell has emf 4.0 V and internal resistance 2.0 Ω. An 8.0 Ω resistor is connected between the...
Hi all,
I am trying to draw a velocity time graph for a tennis ball during a rally. I am aware that the horizontal component of the velocity/speed will be constant, assuming negligable air resistance, and that the vertical component of the velocity will be a sawtooth shape. However I am unsure...
The theory I have read
When you charge an electroscope with a negatively charged rod, electrons are repelled to the bottom of the electroscope and the gold leaf rises. Then when you shine light above the fundamental frequency on the top plate of the electroscope, electrons are liberated from...
