3   1 A power station generates power of 3.0 GW. What is the energy produced for a time interval of 2.0 ps? A 6.0 x 10-15 TJ B 6.0 x 10-6 MJ C 6.0 x 103 nJ D 6.0 x 106 J 2 The perpendicular sides of a right angle triangle have lengths (9.0 ± 0.2) cm and (7.0 ± 0.2) cm. The length of the hypotenuse is calculated from these two measurements. What is the uncertainty of the length of the hypotenuse? A ± 0.2 cm B ± 0.3 cm C ± 0.4 cm D ± 0.5 cm 3 Ah Seng wanted to measure the period of a pendulum, but he did not have a stopwatch. So he used a wall clock instead. He noted the start time for 20 oscillations to be (12.0 ± 0.5) s, and the stop time to be (57.0 ± 0.5) s. What is the period of the pendulum? A (2.25 ± 0.03) s B (2.25 ± 0.05) s C (2.3 ± 0.5) s D (2 ± 1) s 4 A ball is released from point P, and bounces once on the floor. Which of the following graphs correctly shows how its velocity v varies with displacement s with respect to P? A B C D 5 A stone is thrown at a velocity of 12 m s -1 at an angle of 25o above the horizontal. What is the magnitude of the change in velocity from its starting point to the highest point in its path? A 1.1 m s-1 B 5.1 m s-1 C 5.8 m s-1 D 12 m s-1 v 0 s v 0 s v 0 s v 0 s
