Sample Short Written Answer Questions :
Guidance note to candidates :
** When responding to short answer questions, candidates are advised to note the instructions provided in the question and also the number of marks available.

** For example, a question that includes the instruction “state three” and indicates that there are three marks available requires three brief points; likewise, a question with an instruction to “explain” something and which has six marks allocated to it requires six in-depth points relevant to the question in order to secure each of the marks available.

1. Explain what is meant by the term Force. Using an example, demonstrate how Force is calculated. (4 Marks)
2. Explain, using examples, how an increase in heat affects solids. (6 marks)

3.a) Define the term jet reaction and state how this is measured.
b) Calculate the reaction of the water leaving a 25mm nozzle if the pressure is 7 bar. (6 marks)

4.a) Define the term compound and illustrate your answer with appropriate examples.
b) Define the term mixture and illustrate your answer with appropriate examples. (4 marks)

5. Define Ohm’s Law and, using examples, show how Ohm’s Law can be applied to solve electrical problems. (4 marks)
