1a wat's exothermic n endothermic reactionaii xplain d work of a catalyst in d activation energy2ai an atom wit a configuration of 2.8.4 xplain d type of bond it will undergo n state why2aii diff btw a covalent n metalic bond.

quantities as either
fundamental or derived:
amount of
substance,frequency,temperature
intensity,power and current
question2. How far wil a stone
fall during the sixth second of
its fall from rest?(g=10ms2)
question 3. A body of mass
0.6kg is thrown vertically
upward from the ground with a
velocity of 20m/s. Calculate its
potential energy at its
maximum height(g=10ms2)
question 4(a) define work 4(b)
a load of mass 80kg fell down
from the floor of a lorry which
is 1.3m high. Calculate workdone
by gravity on d load (g=10ms2)
question 5. Mention three
phenomenon that result from
refraction of light. Question 8.
State law of electromagnetism.
Question 9(a) define nuclear
fission. 9(b) state two
advantage of fusion over
fission. Question10(a) mention
two type of x-rays. 10(b)give
two diffrences between the
type in(a) above. U are to
answer only 5question here.
Expect d rest.
