The temperature of a body is measured indirectly by making use of the fact that certain physical property of a substance changes linearly with the temperature
If the value of the thermometric property X differ linearly with temperature T, then selecting the simplest possible relationship
T(x) = aX + b
Where the constants b and a must be measured. This linear scale seems that each interval of temperature corresponds to the similar change in the value of the thermometric property. To measure a temperature on this scale two calibration points are select whose temperatures are described as T1 and T2 arbitrarily. The relative thermometric property X1 and X2 are measured..
The humidity of air can be determined by use of two different thermometers; a 'dry bulb' thermometer and a 'wet bulb' thermometer. With reference to a suitable text book, explain
what is radioactivity?
How many planets are found till now? Nine.
Fibre optics: Light travels in straight lines, even though lenses and mirrors can deflect it, light still travels in a straight line between optical devices. This is fine for
Q. Can you define Solar Constant? The luminosity of the Sun L is 3.827×10 26 Watts. When the Sun is straight overhead on a clear day how many watts would we expect to illumina
Why rotation of rigid bodies through finite angles not a vector? Ans) Because it does not obey one of the laws of vector algebra(law of commutativity).
A body of mass 2 kg thrown vertically upwards with a velocity 40 m/s comes to instantaneous rest at a height 50 m. Is there any other force (other than gravitational force), if yes
Correction of short sightedness To remove this defect a convex lens is used in front of eye.
Describe Acceleration In physics, acceleration is the rate at that the velocity of a body changes with time. In common, velocity and acceleration are vector quantities, along w
