PHYSICS ANSWERS
==================

PHYSICS OBJ:
1-10 CEABCBAABB
11-20: DCCBCBCCAE
21-30: BECDDBEDDE
31-40: DBAEADBABA
41-50: CBDCBBBDCB
51-60: CEDDCBAEAA

PART I - ANSWER 6
1ai)
i)propellant
ii)nozzle

1aii)
i)used for communication
ii)used for access geographically dispersed terrains and uneven topography that characterise the nations landscappe

1b)
Given: Object distance for eyepiece, U=3.0cm
Final image distance, V=?
Focal length of eyepiece, F=5.0cm
using the mirror/lens formular
1/f=1/u+1/v
1/5=1/3+1/v
multiplying through with 15v(1.cm)
3v=5v+15
3v-5v=15
-2v=-15/2
V=7.5cm
the final image is virtual and 7.5cm from the eyepiece on the same side of the eyepiece as the object

2)
Given Radius, r=25m
linear velocity, v=20m|s
centripetal acceleration,a=?
Using:
a=V^2/r2
a=20^2/25
a=16m|s^2



(6a) Wavefront is defined as the locus of all the particles
of a medium vibrating in the same phase at a given
instant. The phase difference between any two
points situated on the same wave front is zero the
shape of a wavefront depends upon the shape of the
source of disturbance. 



(6b)types of
wavefronts

- Spherical wavefront:-
If the source disturbance is a point source (O), then
the wavefront is spherical.


-Cylindrical wavefront:-
If the source of disturbance is a slit AB (i.e. line
source) then the wavefront is cylindrical because all
the points equidistant from the source lie on the
surface of the cylinder.


-Plane wavefront:-
At a very large distance from the point source, a
small part of the spherical wavefront appears plane
and this part of the spherical wavefront is called
plane wavefront. Thus, a spherical wavefront
appears as plane wavefront after traveling a large
distance from the point source.



9a)
i)over charging (for secondary cell)
ii)self discharge (for primary cell)

9b)
self discharge- a primary cell lose a considerable percentage of their charge when stored at room temperature, this is due to non-current-producing "side" chemical reactions that occur within the cell even when no load is applied




10)
i)fusion is more easily achieved with lightest elements such as hydrogen
ii)the raw materials required for fussion are more cheaply and readily available
iii)fusion process produce less dangerous by product


PART II - ANSWER 4
12ai)
Newton's second law of motion states that the rate of change of momentum is proportional to the impressed fotvr and takes place in the direction of the force

12aii)
i)a swinging pendulum
ii)The motion of the balance wheel of a watch

12bi)
Resultant force is that single force which acting alone will have the same effect in magnitude and direction as two or more forces acting together

12bii)
Equilbrum force is that single force which will balance all the other forces taken together. It is equal in magnitude buy opposite in direction to the resultant force

12ci)
Resultant,Force,F=sqr4^2+3^2
F=sqr16+9
Fsqr25=5N

12cii)
using F=m(v-u)/t
5=5.5(v-2)/(5*60)
5*60*5=5.5(v-2)
=5.5(v-2)=1500
V-2=272.7
V=272.7+2
V=274.7m|s
final velocity of body = 274.7m|s
=======================
13ai)
i)Solar energy is for providing a cheap and clean source of hot water supply.
ii)Solar energy provides electricity supply
13aii)
Renewable energy are those that can be replaced as they are used up. They can be continually replenished as they are exploited and utilized while Non-Renewable energy are those that cannot be replenished as they are used up

13b)
The principle of conservation of linear momentum us also utilized in the propulsion of jet aircraft. Gases are burnt within the combustion chambers of the engine. As jets of hot gases are expelled downwards through the tail nozzle at very high speeds from the aircraft, an equal and opposite momentum is given to the rocket or aircraft which then moves

13c)
Given: mass, m=0.2kg
heat lost,it=4200J
intial temperature cost r= 100'C
final temperature cost=?
S. It . c of water, C10=4200J/kg/k
using:
heat lost= M10, C10 (cost-tf)
400=0.2*4200*(100-costf)
=4200/0.2*4200
100-costF=5
100-5=costf
=cost=100-5
costf=95'C
final temperature=95'C
=======================

14ai)
A transverse wave is one which travels perpendicularly to the direction of the vibration producing the wave.

14aii)
i)Light Wave do not need a material medium for preparation, but sound wave does
ii)Light wave cannot be plane polarised but sound wave can

14b)
Given Y= 4sin (100x22/7xt/2 + 0.5x)
Comparing with
Y = A sin (2xPIxft + 2pi/pi x) Note : {the PI is the 22/7}

14bi)
2 x 3.142/0.5 = 12.56cm
Hence Wave length is 12.56

14bii)
Also 1000PI/wave length = 2PI F
= 1000PI/12.56 = 500/12.56
= 39.8Hz

14biii)
Speed (v) = F x Wave length 
= V = F x Wave Length 
V = 500/12.56 x 12.56‎
= 500cm/s 
Conversation to M = 500/100
= 5m/s‎

15a)
Coulomb's Law state that the magnitude of the electrostatic force between two point charges is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between them.

15bi)
diagram
R1
R2
R3
I<-V
15bii)
let equivalent resistance be R
1/R=1/R1+1/R2+1/R3
1/R=R2,R3+R1,R3+R1,R2/R1,R2,R3
R=R1,R2,R3/R1,R2,+R2,R3+R1,R3

15C)
Given; R=20n,C=4HF,F=50H2,TI=3.14
z=sqr R^2+(1/2TiFc)
z=sqr200^2+(1/2*314*50*4*10^-6)
z=sqr200^2+796.178^2
z=sqr40000+633900
z=sqr673900
z=821n
