QUESTION 5 QUESTION 5 Twо identicаl metаl spheres, A аnd B, оn an insulated surface, carry charges оf +2,4 nC and -3 nC respectively. The two spheres are brought into contact and then moved back to their original positions. 5.1 Before the spheres are brought into contact, calculate the number of electrons in excess on sphere B. (3) 5.2 Calculate the net charge of the two spheres when they are in contact. (3) 5.3 Calculate the new charge on each sphere when they are moved back to their original positions. (2) 5.4 Calculate the number of electrons that were transferred from the one sphere to the other during contact. (4) [12]

QUESTION 2 2.1 Study the diagram below illustrating a transverse wave: Use the suitable letter(s) to indicate the following of the wave: 2.1.1 Amplitude (1) 2.1.2 A trough (1) 2.1.3 Wavelength (1) 2.2 Define the term period. (2) 2.3 Calculate the period of a wave with a speed of 4 x 103 m.s-1 and a wavelength of 800 mm. (4) 2.4 Two girls, standing at opposite ends of a rope, each makes a pulse of the same speed. Pulse A, with an amplitude of 4 cm, moves to the right and pulse B, with an amplitude of 6 cm, moves to the left. The pulses meet at point C. 2.4.1 Define the principle of superposition. (2) 2.4.2 Name the type of interference that takes place when the pulses meet at point C. (1) 2.4.3 Use the principle of superposition to determine the amplitude of the resultant pulse at point C. (2) 2.4.4 How will the amplitude of pulse A be affected after passing point C? Write down only INCREASES, DECREASES or REMAINS THE SAME. (1) 2.5 Dolphins communicate through the emission and reception of sounds. A young dolphin was separated from its mother and started whistling at a frequency of 130 kHz to call her. The speed of sound in seawater is 1 480 m∙s-1. 2.5.1 Calculate the wavelength of the young dolphin's whistle. (3) 2.5.2 Another dolphin hears the distress call of the young dolphin after 2 s. How far apart are the two dolphins from each other? (2) [20]
