1.Micrometer screw gauge

3. Effort would reduce
4. Flow from a to B
5. Pressure difference between liquids in A and B is P = egh where e is liquid, g = acceleration due to gravity and h is height
But force = P x cross section area of siphon, P = F/A
Thus F = egh A Since e.g. A are constants
Fα h
6. No change in flow OR the flow will still continue
7. Oil spread until it is one molecule thick or film taken as a perfect circle or oil drop has been taken as perfect sphere/ cylinder/ uniform thickness
8. The liquid expand uniformly, expansion is measurable ( large enough), thermal conductivity
9. Rectilinear propagation/ light travels in a straight line
10. Water/ or glass are poor conductor of heat
11. Each material is brought in turn to touch the cap. The conductor will discharge the electroscope while the insulator will not ( accept bring near conductor gauge)
12. Can be short – circuited without being destroyed
 Longer life/ electrolyte never need attention
 Can stay discharged without being destroyed
 Can be charged with large currents faster charging
 More rugged/ not damaged by rough condition of use/ robus
 Delivers large current, light
13. Surface tension / adhesive forces supports water column or more capillarity in tube 2 than tube 1
 Surface tension is the same in both tubes and equal to the weight of water column supported
 Narrow tube has longer column to equate weight to wider tube
 Volume of water in the tubes is same hence narrower tube higher column

14. – Length of conductor in the field
– Angle between conductor and fields
15. All ferromagnetic materials are attracted by magnets or any magnetic materials is attracted
16. – increasing the tension
– Reducing the length
17. At equilibrium sum of clockwise moment = sum of anti – clockwise moments
Clockwise moments = P x X = QY
Px = Qy
18. h glass = V air / V glass 1.5 = 3 x 108  g
Vg = 3 x 108 / 1.5 = 2 x 108 ms-1
19. V = f  sine V is constant reducing f to 1/3   increases 3 fold
20. While light is composed of seven colour different/ many colour. For each colour glass had different value of refractive index/ different velocities of different . So each colour is deviated differently causing dispersion

21. A body at rest or in state of uniform motion tends to stay in that state unless an unbalanced force acts on it.

22. Heat capacity is quantity of heat required to raise the temperature of the body by 1 k or 1 0C while, specific heat capacity is quantity of heat required to raise temperature of unit mass of body by 1 k/ 10 C.
