===========


1)
decrease in height (h)
increase in time (t)
this shows that distance changes with time
============

2)
given that U=15m3^-1
R=U* sqr2h/g
h=20m
g=10
R=15*sqr2*20/10
R=15*sqr40/10
R=15*sqr4
R=15*2=30m
R=30m
===========

3)
i)Brownian motion
ii)Atomic size
iii)Expansion
===========

4)
L1=14cm F1=4N,F2=6N
L2=4cm, Lo=?
Using hooke’s law
4/14-Lo*6/4-Lo
4(4-Lo)=6(14-Lo)
16-4Lo=64-6Lo
-4Lo+6Lo=64-16
2Lo=48
Lo=48/2
Lo=24Cm
============

5a)
i)force
ii)length
5b)
by increasing the density mosquitoes lavrva than the density of water
===========

6)
A)Energy efficient- so far the best light for interior lighting
B)Low production cost (of tubes, not of the ballasts)
C)Long life of tubes
===========

7)
i)It requires low voltage sources for it to function
ii)It cannot be easily broken
iii)It is cheaper and quite easy to manufacture
===========

8b)
If their distance and masses are doubled their corresponding force would also be doubled and the work done respectively
I.e.Workdone=Force * distance
Force= Mass * Acceleration
W= Mg * d
|
Increase

8c)
-Acceleration due to gravity
– At maximum height, final velocity is zero

8d)
i)pushing someone on a swing.
ii)Tuning a radio to a particular frequency.
============

10a)
A wave front is an imaginary surface passing through the points of a medium oscillatory in phase
10b)
i)Priam periscope used in harmod car
ii)prismatic bihocular to see round corner
10bii)
i)refractive indege of the glass prism
ii)the angle of incident of the roy
==========

12ai)
Nuclear fission is a nuclear reaction in which a heavy nucleus splits spontaneously or on impact with another particle, with the release of energy.

12aii)
A graphite reactor is a nuclear reactor that uses carbon as a neutron moderator, which allows un-enriched uranium to be used as nuclear fuel.

12aiii)
Boron rods are used in nuclear reactors to control the fission rate of uranium and plutonium. They are composed of chemical elements such as boron, silver, indium and cadmium that are capable of absorbing many neutrons without themselves fissioning.

REASON WHY STUDENTS FAIL

(1) Cheap/fake runz:
Alot of website are out there gving free or fake runz. imagine such a site not considering the results of students, compose fake answer or give the students fake runz. Most of the fault goes to students risking their own exams for cheap/free runz.

(2)Waiting to get free runz when we post it:
Normally, we do post answer late on the site for those that cant pay for the runz,
obj posted 10mins to the end,
theory posted 20mins to the end.
Tell me how do you want to pass by waiting for free answers when those that paid for the runz has finished, you are just starting.

What you dont know is that nothing is free, even in freetown. Learn how to pay for what you need most. Be wise and try harder to pass
