This question requires a qualitative answer seeing as we do not have an expression for the time period of a pendulum undergoing damped SHM. This is what the examiners will be expecting.There are a few dif...

First off draw the circuit. The voltage across each resistor is equal (i.e. 6V). From here we just have to use Ohm's law (V = I x R) to calculate the currents across each resistor. This gives us:
R1;...

The equation used here is speed = distance / time (s=d/t). Firstly the 30 ms^-1. Rearrange the equation to find distance (st=d). 5ms^-1 x 10s = 50m. The second stint is 6ms^-1 x 5s = 30m. This makes the t...

Part iGravitational Potential Energy (GPE) = mass x gravitational acceleration constant x heightGPE = 2 x 9.81 x 10 = 196.2JPart iiConservation of energy states that the sum of the GPE and K...

The Earth's atmosphere scatters incoming light from the sun. This incoming light is made up of lots of different colours. Each colour of light has a different wavelength and because of this, different col...
