T against L T against L² T against 1/L T² against L T against √(L) would also be acceptable 2 / 10 2) Which phrase best describes the following graph? s increases at a steady rate. s increases as t increases. s is directly proportional to t. s is linearly related to t. 3 / 10 3) In the pendulum experiment, which variable should be controlled? Length of the pendulum Mass of the pendulum bob Period of the pendulum Calculated average period 4 / 10 4) Which statement best describes the relationship between P and Q as shown on the following graph? P increases linearly with Q. P is directly proportional to Q. P is inversely proportional to Q. P increases with Q. 5 / 10 5) Distance and time values (d & t) are measured and recorded in the table below. How should the calculated average velocities v be recorded? X: 1.6 Y: 3.1 X: 3.21 X: 1.61 Y: 3.10 X: 3.21 X: 1.6 Y: 3.1 X: 3.2 X: 1.61 Y: 3.06 X: 3.21 6 / 10 6) What will be the shown on the stopwatch one second after this time: 1:0097 0:5998 0:6097 1:5997 7 / 10 7) Which action is most likely to improve the reliability of an experiment? Taking only one reading Changing several variables at the same time Repeating measurements and calculating a mean Ignoring all unexpected readings 8 / 10 8) A vernier callipers reads 0.2 mm when no object is being measured. This is an example of: a calculation error a random error an anomalous result a zero error 9 / 10 9) When reading the volume of water in a measuring cylinder, the student’s eye should be: below the meniscus as far away as possible level with the meniscus above the meniscus 10 / 10 10) What is the relationship shown on the following graph? s is directly proportional to t. There is a linear relationship between s and t. s increases as t increases. s is inversely proportional to t. Your score is Restart quiz
