# WAEC GCE Physics Practical Questions and Answers 2023/2024 | Alternative to Practical

WAEC GCE Physics Practical Questions and Answers 2023. Many WAEC candidates find it difficult to answer the WAEC GCE Alternative to Practical Physics correctly due to not understanding the questions. I will show you the best way to answer WAEC GCE Physics Practical questions and make a good WAEC result in your Physics examination.

You need to understand the WAEC GCE Physics Practical marking scheme before attempting any question so as to present your answers in such a way that it will look attractive to the examiner to earn you big marks.

Bear in mind that every single procedure is awarded marks. So, ensure you do not skip any step while reporting and presenting your alternative to practical results. And do not forget to remember that the units are very important.

The Physics Practical question paper will consist of three areas and general Physics questions namely:

1. Optics
2. Electricity
3. Mechanics

You will be expected to take your readings from an alternative to a practical experiment, take readings and tabulate your values, plot graph, state precautions to be taken during the experiment, and report observations.

What you will see will not be far from the WAEC Physics Specimen given to your school.

Note: Ensure you avoid parallax errors while taking your readings to get accurate results and do not forget to choose lines of best fit while plotting the graph. It is not compulsory that all the points will enter the line.

SPECIFIC HEAT CAPACITY: of a substance is defined as the quality of heat supplied or required to raise the temperature of a unit mass of 1kg through a unit rise in the temperature of 1kelvin.(K)

3a.( IX.)

2. Large current or voltage must not be passed into the meter because it might damage it.

3. The calorimeter must be properly lagged to prevent heat loss.

### Practice questions

1(a)

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.

(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.

(xi) State two precautions taken to ensure accurate results.

(b)(i) Define simple harmonic motion

(ii) Determine the value of L corresponding to t = 12s from the graph in 1 (a).
