(i) A stone is thrown vertically upwards with an initial velocity of 60ms. Find a) the maximum height attained by the stone
b) the time taken to reach the maximum height (Take g = 10 ms?)
c) the net displacement if the stone returns back to point from where it was thrown up.

Two solutions of the same uv-absorbing molecule were analyzed by uv-vis spectroscopy on the same instrument using 1 cm pathlength cells. use data from the table to calculate by what percentage the concentration of solution b is compared to that of solution a. sample absorbance at 315nm a 0.45 b 0.80
