Questions in 9702/43 Oct/Nov 2017
- Question 1
(a) State (i) what may be deduced from the difference in the temperatures of two objects, (ii) the basic principle by which temperature is measured. (b) By reference to your answer in (a)(ii), explain why two thermometers may not give โฆ
- Question 2
(a) State, by reference to simple harmonic motion, what is meant by angular frequency. (b) A thin metal strip is clamped at one end so that it is horizontal. A load of mass M is attached to its free end. โฆ
- Question 3
(a) Define gravitational field strength. (b) Explain why, for changes in vertical position of a point mass near the Earthโs surface, the gravitational field strength may be considered to be constant. (c) The orbit of the Earth about the Sun โฆ
- Question 5
(a) (i) State Coulombโs law for the force between two point charges. (ii) Two point charges are situated in a vacuum and separated by a distance R. The force between the charges is FC. On Fig. 5.1, sketch a graph โฆ
- Question 6
Two capacitors P and Q, each of capacitance C, are connected in series with a battery of โฆ
- Question 8
A thin slice of conducting material is placed normal to a uniform magnetic field of flux density B, as shown in Fig. 8.1. magnetic field flux density B current โฆ
- Question 9
(a) In computed tomography (CT scanning), it is necessary to take a series of many X-ray images. Outline briefly the principles of CT scanning. (b) A student creates a model for CT scanning. A section is divided into four voxels, โฆ
- Question 10
(a) The mean value of an alternating current is zero. Explain why heating occurs when there is an alternating current in a resistor. (b) Transmission of electrical energy is frequently achieved using alternating high voltages. Suggest why (i) high voltages โฆ
- Question 11
(a) State what is meant by a photon. (b) Indium-123 (123 49In) is radioactive. A nucleus of indium-123 emits a ฮณ-ray photon of energy 1.1 MeV. Determine, for this ฮณ-radiation, (i) the frequency, frequency = Hz (ii) the momentum of โฆ
- Question 12
(a) A radiation detector is placed close to a radioactive source. The detector does not surround the source. Radiation is emitted in all directions and, as a result, the activity of the source and the measured count rate are different. โฆ
