K.C.S.E Physics Q & A - MODEL 1998PP2QN02
a) You are provided with two straight open tubes each about 1m long, a sound source, a sound detector and a reflecting surface. With the aid of a labeled diagram, describe an experiment to show that the angle of incidents is equal to reflection for sound waves.
b)Fig. 1 shows a block with a graduated side, and of dimension 4cm x4cm x 4cm x 16cm, just about to be lowered into a liquid contained in an overflow can.
During an experiment with this set-up, the following information was recorded;
-The block floated with three quarters of it submerged
-Initial reading of balance=0 grammes
-final reading of balance= 154 grammes.
Use the information to determine the density of the:
(i) Block (ii) Liquid
(Use g= 10ms2 . give your answers to 1 decimal place.)
