a student investigates the time taken for a drop of water to fall from a tap through a distance of 50cm. fig .2.1 shows the setup of the experiment. (a) The student opens the tap slightly so that it drops as shown in fig.2.1. He measures the time,t,for 20 drops. He repeats the measurements five times table2.1 shows the readings. Trial1 time taken for 20 droplets 11.41. Trail 2 Time taken for 20 droplets 11.74. Trail 3 Time taken for 20 droplets 09.05. Trail4 Time taken for 20 droplets 11.01. Trail 5 Time taken for 20 droplets 11.78. (i)Use table to identify the anomalous result .(ii) Use table2.1 to calculate the average time,t,for 20 drops.(iii)Use answer in (a)(ii)to calculate the time,T,for 1 drop. (b) Another student does the expirement shown in fig2.1.
He finds the time,t,for 10 drops.
He determines the time,T,for 1 drop of water T=5.62s.(i) Calculate T²and state the unit for T².(ii) Calculate the constant,k, using the equation k,

k=distance through which
