ThePhysicsGurus 970242ON20 Completely Solved CIE AS A Level 9702 Physics Paper-4 Structured Questions The Earth may be considered to be a uniform sphere of radius 6.4 106m with its mass of 6.0 1024 kg concentrated at its centre. A satellite of mass 2.4 103 kg is launched from the Equator.
It is placed in an equatorial orbit at a height of 5.6 106m above the Earths surface. Before the satellite in b is launched its speed at the Equator due to the Earths rotation is 470ms1. Suggest why the energy required to launch the satellite depends on whether the satellite in its orbit is travelling from west to east or from east to west. The atoms of an ideal gas occupy a container of volume 2.30 103m3 at pressure 2.60 105Pa and temperature 180K as illustrated in Fig.
2.1 A simple pendulum consists of a metal sphere suspended from a fixed point by means of a thread as illustrated in Fig.
3.1. The sphere of mass 94.0g is displaced to one side through a horizontal distance of 12.7cm.
The centre of gravity of the sphere rises vertically by 0.90cm. Use your answer in ii to show that the angular frequency ω of the oscillations of the pendulum is 3.3rads1. An analogue signal is to be transmitted in digital form. The transmission system may be represented in block form as in Fig.
4.1 b An isolated solid metal sphere of radius 0.15m is situated in a vacuum as illustrated in Fig.
5.1. Use information from b to show on the axes of Fig.
5.2 the variation of the electric field strength E with distance x from the centre of the sphere for values of x from x 0 to x 0.45m State three functions of capacitors in electrical circuits.
