PHYSICS THEORY:

2i
Linear expansivit of a metal can be defined as the increase length per unit per degree rise in temperature
i.e. & =increase in length
Original length *temperature rise
2ii
Young molecule can be define as the ratio of the stress to the strain
i.e y= F/A
E/l
3a
Diffusion is a tendency of molecule to migrate and fill an empty space due to random motion.
3b
I. Density
II. Temperature
5
Oml’s state that the current flowing through metallic conductor is directly proportional to it potentially difference across it to ends provided that temperature and other physical quantity remain constant v=

Bi ohmic material
a Resistor
Ii non ohmic material
a bulb
6
Surface lension is the force per unit length on either side on the maginary line drawn on the liquid surface at rest
B adhesion is the force of attraction between molecules of different kinds while cohesions is the force of attractions between molecules of the same kinds
11 what is wave
11 Wave is a disturbance which travel thought a medium transferring energy from one point to another without causing movement of the medium
B I reflection
Ii refraction
iii diffraction
iv interference
