Question 12 (a) i. Describe an experiment to demonstrate Brownian motion. [2] ii. Briefly explain Brownian motion. [2] (b) A ball of mass \( 2.69 \mathrm{~kg} \) is attached to a cable of length \( 1.85 \mathrm{~m} \). The ball is spun in a horizontal circle using a centripetal force of \( 1230 \mathrm{~N} \). i. Determine the linear velocity of the ball. [2] ii. Determine the angular velocity of the ball. [2] iii. Find the time period of the ball. [2]
