A container ship: 10 m s–1 B Olympic sprinter: 0.1 km s−1 C racing car: 9000 cm s–1 D snail: 0.01 km h–1 2 Rain is falling vertically down at a constant speed of 8.0 m s−1. A passenger on a bus travelling at a constant velocity of 60 km h−1 on a horizontal surface sees the side windowpane and the tracks caused by the rain. At what angle does the rain track appear to be making from the vertical? A 8o B 26o C 64o D 82o 3 A set of repeated measurements is made of a fixed quantity. An average of these measurements is calculated. What is the effect of averaging on the random error and the systematic error in the measurements? A Random error and systematic error are both reduce
