K.C.S.E Physics Q & A - MODEL 1999PP2QN06
a) Explain the following observations: ice cube float on water and solid benzene sinks in liquid benzene.
bi) You are provided with the following:
An overflow can - A beaker -A spring balance
A metal block -Water and - String
Describe an experiment to verify Archimedes principle.
ii) A block of wood weighing 2.0N is held under water by a string attached to the bottom of a container. The tension in the string is 0.5N. Determine the density of the wood.
ci) Define half – life of a radioactive material.
ii) Figure 6 shows a graph of the variation of the number of atoms of a certain radioactive material with time.
Figure6: Determine the half – life of the material
K.C.S.E Physics Q & A - MODEL 1999PP2QN05
a) A circuit consists of a battery, a metal wire, an ammeter and a switch connected in series. The switch is closed and the ammeter reading noted. The metal wire is now heated. State the observations made on the ammeter reading and give a reason for your answer.
