Questions in 9702/42 Oct/Nov 2020
- Question 1
(a) Define gravitational potential at a point. (b) The Earth may be considered to be a uniform sphere of radius โฆ
- Question 2
(a) State what is meant by the internal energy of a system. (b) The atoms of an ideal gas occupy a container of volume โฆ
- Question 3
A simple pendulum consists of a metal sphere suspended from a fixed point by means of a thread, as illustrated in Fig. 3.1. thread sphere mass โฆ
- Question 5
(a) (i) State what is meant by a field of force. (ii) State one similarity and one difference between the electric field due to a point charge and the gravitational field due to a point mass. similarity: difference: (b) An โฆ
- Question 6
(a) (i) Define the capacitance of a parallel plate capacitor. (ii) State three functions of capacitors in electrical circuits. โฆ
- Question 7
Electrons in a beam are travelling at high speed in a vacuum. The electrons are incident on a metal target, causing X-ray radiation to be emitted. The variation with wavelength ฮป of the intensity I of the emitted X-ray radiation โฆ
- Question 9
(a) A small coil is placed close to one end of a solenoid connected to a power supply. The plane of the small coil is normal to the axis of the solenoid, as illustrated in Fig. 9.1. solenoid small coil โฆ
- Question 10
(a) A long straight vertical wire A carries a current in an upward direction. The wire passes through the centre of a horizontal card, as illustrated in Fig. 10.1. card current-carrying wire A Fig. 10.1 The card is viewed from โฆ
- Question 11
(a) Electromagnetic radiation is incident on a metal surface. It is observed that there is a minimum frequency of electromagnetic radiation below which emission of electrons does not occur. This observation provides evidence for a particulate nature of electromagnetic radiation. โฆ
- Question 12
(a) (i) Define nuclear binding energy. (ii) Explain what is meant by a nuclear fission reaction. (b) A student suggests that one possible nuclear reaction is 56 26Fe โฆ
