Measurement of length:
If the Zeroth division of the head scale does not coincide with the index line the Screw gauge has Zero error.
If the Zeroth division of the head Scale is below the index line of the pitch Scale, the error is said to be +ve and correction is negative. If the Zeroth division of the head scale is above the index line of the pitch scale, the error is said to be -ve and correction is positive. The Diameter of your pencil and a given pin is measured with a screw Gauge.
In some screw gauges, the Zero error can be eliminated by adjusting the position of the stud (S ).
Same units are used for P.S.R. and L.C.
The last column in finding the diameter of a bob in the tabular form is P.S.R + (C.H.S.R X L.C). Vernier Callipers and Screw Guage are Mechanical Devices.
The least count of an ordinary scale is 1 mm.
To hold the marble tightly between S and S , we used by rotating the Milled head M.1
Determine where r is the position vector.
Light is normally incident on a thin soap film and is reflected. If the wavelength of this light is "L" and the index of refraction of the soap film is "N", complete destructive i
Q. Escape Velocity An object will conquer the force of gravity when its kinetic energy in the direction away from earth exceeds its potential energy. We find the smallest kinet
what will happen if we will walk with the speed of light or faster than it?
Q. Show Conjugate Complex Poles? It is possible that some of the poles of Equation are complex. Since the coefficients ak in Equation are real, complex poles occur in complex c
The effects of open circuits: An open circuit is essentially a break in the circuit. An open circuit in a series circuit will prevent the flow of current through the circuit. W
It is the force that the field would exert on any unit magnetic pole placed in the field. It is also known as magnetic force.
What is the proper formula used to calculate acceleration? There are a few. The most famous is a = F/m, where F is the net force applied to a mass, m. Acceleration is also the
Define: Electric potential. The electric potential in an electric field at a point is define as the amount of work done in moving a unit positive charge from infinity to that
If two forces P & Q act at such an angle that the resultant force r=p. Then show that if P is doubled the new resultant is at right angle Q and it's value is ( 4P 2 -Q 2 ) 1/2
