PHYSICS PRATICAL
1.
(1i)
Centre of gravity =50.5

TABULATE
S/N|A(cm)| B(cm)
1 |10.0 | 51.90
2 |15.0 | 53.50
3 |20.0 | 53.80
4 |25.0 | 54.90
5 |30.0 | 55.80

(1xii)
-I avoided the effect of draught during the experiment
-I avoided error due to parallax on the metre rule
-I balanced the metre rule horizontally on the knife edge before taking my readings



(1bi)
Moment of a force about a point is the product of the force and its perpendicular distance from the point to the line of action of the force. i.e moment=force*time and its unit is Nm

(1bii)
-Sum of forces acting in one direction must equal to the forces acting in another direction.
-The algebraic sum of moment acting about a point must be equal to zero

(3a)
TABULATE
S/N|E(v)|V(v)|I(A)|V^-1(v^-1)|I^-1(A^-1)
1 |1.50|0.80|0.40| 1.250 |2.500
2 |3.00|1.40|0.70| 0.714 |1.429
3 |4.50|2.00|1.00| 0.500 |1.000
4 |6.00|2.50|1.20| 0.400 |0.833
5 |7.50|3.20|1.50| 0.313 |0.667


Precautions:
-I tightened all the wires tightly together
-I ensured clean terminals
-I avoided zero error on the ammeter used

(3bi)
-By using electric cells
-By using electrostatic method

(3bii)
For parallel connection=1/R=1/R+1/R
2Rt=R
Rt=R/2ohm
Total=(R/2)+2
4=(R/2)+2
4=(R+4)/2
8=R+4
8-4=R
R=4ohm
