Which plan best measures a pendulum's period and records a dependable result?
Time 20 complete oscillations between the same reference crossings, repeat the timing, divide the mean time by 20 and record the period in seconds. Time one swing once from an arbitrary release point and record the stopwatch number without a unit. Count 20 oscillations but change the reference point on every pass, then choose the fastest timing. Measure the string length with a stopwatch and report that reading as the period in metres. A liquid's density is required. Which method supplies the needed mass and volume without including the container's mass?
Measure the empty container's mass, add a measured liquid volume, measure the combined mass, subtract the empty mass and divide the liquid mass by its volume. Divide the mass of the filled container by the liquid volume without measuring the empty container. Divide the measured liquid volume by the mass of the empty container. Measure only the liquid's temperature because liquids at one temperature all have the same density. Which investigation gives the strongest school-laboratory evidence for the acceleration of free fall?
Use electronic release and timing for several fall distances, repeat readings, plot distance against time squared and use the gradient to determine g. Hand-time one short fall once and divide distance by time to call the result g. Use several distances but plot distance against time and assume the gradient is g. Measure the object's mass only, because heavier objects always have a larger acceleration of free fall. A learner tests how resultant force affects a trolley's acceleration. Which design is a fair comparison?
Keep the total moving mass and track conditions constant, vary the resultant pulling force, measure acceleration consistently and repeat each setting. Increase both pulling force and trolley mass together, then attribute every acceleration change to force alone. Use a different track surface for every force and keep only the run nearest the expected answer. Measure the trolley's weight once and use it as the horizontal resultant force for all runs. Two insulating materials are compared around identical beakers of hot water. Which procedure supports a valid conclusion?
Use equal water masses at the same initial temperature, identical beakers and coverings, measure temperature at common times and repeat the comparison. Use different water masses and initial temperatures, then call the beaker with the higher final temperature the better insulator. Use identical conditions but read one beaker after 5 minutes and the other after 15 minutes. Change material, beaker size and exposed surface area together to make the contrast larger. Which method correctly determines the resistance of a component at one operating point?
Connect an ammeter in series and a voltmeter across the component, record V and I together, then calculate R = V/I while limiting heating where relevant. Connect both meters in series and divide the ammeter reading by the voltmeter reading. Connect both meters across the component and multiply their readings. Record voltage and current at unrelated settings after prolonged heating, then pair whichever values give the expected resistance. Practise

Three timings for 20 pendulum oscillations are 31.6 s, 31.8 s and 31.7 s. What period should be reported?
1.59 s, from the mean time 31.7 s divided by 20. 31.7 s, because the mean already equals the period. 0.631 s, from 20 divided by 31.7. 95.1 s, from adding all three times without averaging or dividing by 20. A container has mass 52.2 g empty and 84.6 g with 40.0 cm³ of liquid. What is the liquid's density?
0.810 g/cm³, because the liquid mass is 84.6 − 52.2 = 32.4 g and 32.4/40.0 = 0.810. 2.12 g/cm³, from 84.6/40.0. 1.31 g/cm³, from 52.2/40.0. 1.23 cm³/g, from 40.0/32.4. A graph of fall distance s against time squared t² has gradient 4.9 m/s² for an object released from rest. What value of g follows from s = ½gt²?
9.8 m/s², because the gradient equals ½g. 4.9 m/s², because every graph gradient is directly g. 2.45 m/s², because the gradient must be halved. 24.0 m/s², because the gradient should be squared. A motorised trolley moves at constant velocity while experiencing a 1.8 N resistive force. What is the motor's horizontal driving force?
1.8 N forward, so the horizontal resultant force is zero. 0 N, because constant velocity means no forces act. 3.6 N forward, because the driving force must be twice the resistance. 1.8 N backward, in the same direction as the resistance. Equal water samples start at 80 °C. After 10 minutes, sample A is 66 °C and sample B is 59 °C under otherwise identical conditions. Which conclusion is supported?
A's insulation reduced energy transfer more effectively because A had the smaller temperature drop, 14 °C rather than 21 °C. B was better insulated because its final temperature number is smaller. Both were equally insulated because they started at the same temperature. No comparison is possible unless the water in B starts hotter than A. A voltmeter across a resistor reads 3.6 V while the series ammeter reads 0.24 A. What resistance is measured?
15 Ω, from R = 3.6/0.24. 0.864 Ω, from multiplying 3.6 by 0.24. 0.067 Ω, from dividing 0.24 by 3.6. 3.84 Ω, from adding the two meter readings. Practise

A timing table is headed only 'time' and contains 8.2, 8.3 and 3.1 for the same trial condition. What is the best repair?
Add the unit to the heading, repeat the measurement using the same method, retain all readings and investigate whether 3.1 s is anomalous before calculating a representative value. Delete 3.1 immediately and leave the table heading unchanged. Change the 3.1 to 8.1 because it probably contains a typing error. Average all three values and report the bare number without checking the method. A solid has mass 63 g and raises water in a measuring cylinder from 38 cm³ to 46 cm³. What density should be reported?
7.9 g/cm³, because its volume is 8 cm³ and 63/8 = 7.875 g/cm³. 1.37 g/cm³, from 63/46. 0.127 cm³/g, from 8/63. 3.9 g/cm³, from dividing 63 by both the initial and final readings. A learner hand-times one 0.20 m fall and reports distance/time as the acceleration of free fall. Which change repairs the investigation?
Use electronic timing for repeated falls at several measured distances, plot s against t², and obtain g from twice the gradient. Repeat the same hand timing once and keep calling distance/time an acceleration. Use a heavier object once because mass alone determines g. Measure a longer distance but continue using one hand time and s/t as g. A learner says, 'Balanced forces mean the trolley must be at rest.' Which correction is complete?
Balanced forces mean zero resultant force and zero acceleration; the trolley may be at rest or move at constant velocity, with equal opposite forces while moving. Balanced forces mean the trolley always speeds up at a constant rate. Balanced forces mean no individual forces act on the trolley. Balanced forces mean the trolley can move only if the forward force is larger. Material X is tested with 100 g of water at 80 °C, while material Y is tested with 60 g at 65 °C in a different beaker. What is the most important repair?
Repeat with material as the intended change while controlling water mass, initial temperature, beaker, exposed area and elapsed time. Keep every difference because a larger contrast makes the material effect clearer. Compare only the final temperatures and ignore how each sample started. Change the thermometer as well and choose the one giving the largest separation. Successive V–I readings for a wire drift because it becomes hot. Which action best improves a comparison of resistance at the intended temperature?
Use low currents, switch off between paired readings and allow the wire to return to the intended temperature before repeating V/I. Leave maximum current on continuously so the readings change faster. Pair a voltage from the cold wire with a current from the hot wire. Ignore temperature and average every drifting value as though resistance were constant.
