As you want to get the 10th class physics question paper of ICES, so here I am giving you some questions of that paper: Question 1 (a) What are the factors on which the following characteristics of a musical note depends? 1. intensity 2. timbre. (b) How does a trawler man catch fish in deep water? (c) What are the factors on which resistance of a conductor depends? (d) Name the material used for: (i) Electric fuse. (ii) Connecting wire. (iii) Filament of an electric bulb. (iv) Heating element of an electric toaster. (e) Give the harmful effects of global warming on lakes and oceans found frozen during winter. Question 2 (a) Calculate the wavelength of an electromagnetic wave of frequency 15 MHz. (b) State the function of a transformer. (c) State two uses of a cathode ray tube. (d) Show by equations, the effect on the proton number Z and mass number A of the parent nucleus brought about by the two types of radioactive decay. (e) State one industrial use of , , and radiation. Question 3 (a) An engine can pump 30,000 litres of water to a vertical height of 45 metres in 10 minutes. Calculate the work done by the machine and the power. (Density of water = 103 kg/m3, 1000 litre = 1 m3, g= 9.8 m s-2). [3] (b) ‘Renewable sources of energy must be encouraged to meet growing demands of energy’. Give suggestions to support your answer. [3] (c) A pulley system has a velocity ratio 5. Draw a neat labelled diagram of the pulley system to lift a load by applying the effort in a convenient direction. Mark the tension in your diagram. (i) If the efficiency of the system is 80% find its mechanical advantage. (ii) If a load of 10 kgf is pulled up by a distance of 2 m in 10 s, calculate the power developed by the effort (given g = 10 m s-2). ![]() ![]() ![]() ![]() ![]() ![]() ![]()
