Draw a circuit diagram of the electrical circuit in Figure 1 in the space below.

When the current in a lamp is 0.15A, the resistance of the lamp is 40Ω.

Calculate the voltage across the lamp.

Use the equation: V = I × R

State the value of the current shown on the ammeter in Figure 2.

(i) The force that keeps the Earth in orbit around the sun is ​ ​ (a)   attraction.

(ii) The force that opposes motion between two surfaces is​ (b)  

(iii) The force that can move small pieces of paper towards a plastic comb

is​ (c)   attraction

• friction
• electrostatic
• magnetic

Which of these statements is true for a vector quantity?

• It has size only

• It has direction only

• It has direction and size

• It does not have direction or size

Use the equation:

moment of a force = force × distance at right angles to the direction of the force

When the pressure in a container of gas increases, the particles of the gas

• hit the sides of the container less often

• hit the sides of the container more often

• move with lower speeds

• vibrate more energetically about fixed positions

A student investigates the pressure and volume of some trapped gas.

Figure 4 shows the apparatus used.

Suggest what the student should add to the headings of the table in Figure 5.

Use Figure 5 to estimate the volume of gas for a pressure reading of ‘170’.

Suggest two ways the student could improve the investigation.
