page 07 5. During an experiment a student inside a lift stands on a newton balance. lift newton balance not to scale 1.2 m s−2 The mass of the student is 50.0 kg. The lift accelerates upwards at 1.2 m s−2. The reading on the newton balance is: A 60 N B 430 N C 490 N D 550 N E 590 N. 6. Water flows at a rate of 1.0 × 106 kg per second over the Victoria Falls. The Victoria Falls are 120 m high. The total power delivered by the water in falling through 120 m is: A 1.2 × 1012 W B 1.2 × 109 W C 1.2 × 108 W D 8.5 × 10−10 W E 8.5 × 10−11 W. [Turn over
