Solution:
An ohmic conductor is defined as a two-terminal device in which the voltage or current characteristics have a straight line passing through the origin. Silver, copper wire, metals are the examples of ohmic conductors.

Solution:
Displacement can be either positive or negative.

Solution:
Tap water is placed in an open pad and allowed to evaporate. After some time the temperature of water decreases slightly.

Solution:
'Farad' is the unit of capacitance.

Solution:
Uncertainty principle, also called Heisenberg uncertainty principle or indeterminacy principle, statement, articulated (1927) by the German physicist Werner Heisenberg, that the position and the velocity of an object cannot both be measured exactly, at the same time, even in theory.

Solution:
During rainy days, the moisture content is more in the atmosphere and speed or velocity of sound increases with increase in humidity. Hence the sound travels faster on rainy days.

Solution:
Amplitude determines the frequency of a sound wave.
