WAEC GCE Physics Practical Questions and Answers 2022/2023 | Alternative to Practical

Physics practical questions and answers for the 2022 WAEC GCE Many WAEC applicants find it difficult to give proper answers on the WAEC GCE Alternative to Practical Physics because they don’t grasp the questions. To help you get a high WAEC score on your Physics test, I’ll show you how to react to WAEC GCE Physics Practical problems most effectively.WAEC GCE Biology Practical Questions and Answers 2022/2023 | Alternative to Practical

In order to present your comments in a way that will be appealing to the examiner and help you obtain high scores, you must be familiar with the WAEC GCE Physics Practical grading structure prior to responding to any questions.

Remember that each procedure is graded. Consequently, make sure to adhere to all the requirements in order to report and present an alternative to the actual outcomes. Additionally, keep in mind the importance of the units.https://bekeking.com/waec-gce-physics-practical/

Three sections and general physics questions will make up the Physics Practical question paper, and they are as follows:

Optics

Electricity

Mechanics

You will need to gather information from a stand-in experiment, tabulate your findings, create a graph, discuss any safety precautions associated to the experiment, and record any observations.

What you see will be somewhat comparable to the WAEC Physics Specimen that was handed to your school.

Remember to avoid parallax mistake when taking your readings, and don’t forget to choose lines of best fit when plotting the graph for accurate results. It is not necessary to enter every point into the line.

You are provided with two retort stands, two metre rules, pieces of thread and other necessary apparatus. (i) Set up the apparatus as illustrated above ensuring that the strings are permanently 10cm from either end of the rule.

(ii) Measure and record the length L = 80cm of the two strings.

(iii) Hold ends of the rule and displaces the rule slightly, then release so that it oscillates about a vertical axis through its centre.

(iv) Determine and record the time t for 10 complete oscillations. (v) Determine the period T of oscillations.

(vi) Evaluate log T and log L. (vii) Repeat the procedure for four other values of L = 70cm, 60cm, 50cm, and 40cm.

(viii) Tabulate your readings.

(ix) Plot a graph with log T on the vertical axis and log L on the horizontal axis.

(x) Determine the slope, s and the intercept, e on the vertical axis, of the graph.
