PHYSICS PRACTICAL SOLUTION SET
=====================
PLS NOTE THAT THESE ARE NOT THE REAL PHYSICS PRACTICAL ANSWERS BUT IS JUST A GUIDE TO PHYSICS PRACTICAL.
IT WILL HELP YOU TO STUDY YOUR PHYSICS PRACTICAL.
THEY ARE ASSUMED OR LIKELY QUESTIONS AND ANSWERS.
==========
QUESTION 1
Reading:
S/n: 1,2,3,4,5,6 L(cm):
150.0,120.0,100.0,80.0,60.0,40.0
t(sec):
4.800,4.100,3.300,2.600,1.900,1.200
t^-1(Sec^-1):
0.208,0.244,0.303,0.385,0.526,0.833 t^2(sec^2):
23.40,16.81,10.89,6.76,3.61,1.44
L/t^2(m/s^2):
6.510,7.139,9.183,11.83,16.6,27.7

Precautions:
-I ensured the experiment was not affected by air interference when determining the balance points
-I ensured the mass roll down freely as being influenced under gravity
-I ensured that the readings were taken without any error

DEFINITIONS YOU NEED TO KNOW:

FORCE OF GRAVITY: The total
gravitational force which acts on a body and so enables it,in turn to exert an equal force on its support

DISPLACEMENT: This Is defined as the distance moved in a specified direction

NEWTONIAN MECHANICS: This is
defined as the rate of change of distance moved with time in a specified direction or rate of change of displacement

UNIFORM VELOCITY: A body moved
with uniform velocity if its rate of change of distance moved with time in a specified direction is constant


ACCELERATION: This is defined asthe rate of change of velocity with time

INERTIA: The tendency of a body to remain at rest or if moving,to continue its motion in a straight line


UNIFORM ACCERATION: A body moved with uniform acceleration,ifits rate of change of velocity with time in a
specified direction is constant


DECCELERATION: A decreasing velocity or slowing down is usually called retardation.::::::

QUESTION 2
Readings: S/n: 1,2,3,4,5,6,7
D: 100,90,80,70,60,50,40
D^2:
10000,8100,6400,4900,3600,2500,16
X1:
80.60,70.20,59.10,47.80,29.00,20.35, X2:
18.30,19.00,20.00,22.00,7.60,4.50,1.0
L
(X1-X2):
62.20,51.20,39.10,24.70,21.40,15.85,

PRECAUTIONS: -i ensured parallax when reading
the metre rule.
-i ensured that the intensity or source of light was maintained.

Expected Question: An illuminated object is placed on the
axis of a converging lens and a magnified image is obtained on the screen.
If the distance of the image from the lens is 45cm and the
magnification is 2,cal the focal length of lens.

SOLUTION:
V=45.00cm
m=2
u=?
M=v/u=45/2
22.5cm F=uv/v+u
22.5*45.00/22.5+45.00
=1012.5/67.5
=15cm



:::::::.QUESTION
3 Readings:
S/n: 1,2,3,4,5
L1: 20,40,60,80,100
L2: 10,15,25,35,45
I1(A): 0.50,0.40,0.32,0.22,0.14
I2(A): 0.58,0.53,0.45,0.41,0.37 I1^-1: 0.20,2.50,3.13,4.55,7.143
I2^1: 1.724,1.890,2.22,2.44,2.70

PRECAUTIONS:
-I will ensure that the key is opened when no reading is taken to avoid battery wastage.
-I ensured tight connection -I ensured error due to parallax
when taking reading from the ameter
-i will ensure that the circuit element are tightly connected to ensure
accurate result

NEED TO KNOW:
-Electromotive force is the
potential
difference between the terminals
of
a cell when no current is flowing in
the circuit.
=======

NOTE THAT ^ MEANS RAISE TO
POWER.
Eg: 2^4 Means 2 raise to power 4.
L^-2 means L raise to power
-2(minus two)
-COMMA MEANS NEXT LINE. Eg: x: 4,2,3,4,5 means that you
draw a table, then under x, you
will get 4, under 4 is 2, under 2 is
3, under 3 is 4 and so on..........
