Two pulses are travelling towards each other. (i) half of cycle takes \(\pi \sqrt {\frac{L}{g}} \) other half takes \(\pi \sqrt {\frac{x}{g}} \) and combine to give result; \[\left( {\frac{\pi }{g}\left( {\sqrt L  + \sqrt x } \right)} \right)\]. 2 The Extended Essay J (kg*m^2/s^2) (Unit for energy) In scientific notation, values are written in the form a*10^n, where a is a number within 1 and 10 and n is any integer. W = Work done. International Baccalaureate® - Baccalauréat International® - Bachillerato Internacional®, fractional uncertainties are 0.07/\(\frac{1}{{14}}\). All copyrighted materials belong to their respective copyright owners. In this case, you can divide the uncertainty for 20T by 20 to get the uncertainty in T. Español. State the unit for your answer to (b)(i). two worst fit lines drawn through extremes of error bars; The diagram shows an analogue meter with a mirror behind the pointer. The temperature is measured using a liquid in glass thermometer. D. 5. Volt. Taking logs of both sides of the equation gives us : a) Plot a graph of N against t.: b) Use three points on the graph to show that the equation of the graph has the form predicted by the theory and, in doing this, calculate the value of the decay constant.
