Halkan waa xalka su'aalaha: 9. c) In the space below, redraw the circuit to show how a voltmeter and ammeter are connected correctly. To connect a voltmeter and ammeter correctly in a circuit: • An ammeter must be connected in series with the component to measure the current flowing through it. • A voltmeter must be connected in parallel across the component to measure the potential difference (voltage) across it. 10. a) Define friction. Friction is a force that opposes the relative motion or tendency of motion between two surfaces in contact. 10. b) Write down two ways of reducing friction between surfaces. • Using lubricants like oil or grease between the surfaces. • Making the surfaces smooth or using ball bearings/rollers. 10. c) State one advantage of friction in real life. Friction allows us to walk without slipping and enables vehicles to brake and move on roads. 10. d) What is the name given to specify friction in a liquid? The name given to specify friction in a liquid is viscosity. Last free one today — make it count tomorrow, or type /upgrade for unlimited.
