Q Define: specific rotation?
Precise rotation for a given wavelength of light at a given temperature is defined as the rotation produced by one-decimetre length of the liquid column containing 1 gram of the active material in1cc of the solution.
That is S = θ / l c
Randomly polarized light (such as sun light) with intensity of I 0 passes through three polarizers (P 1 , P 2 , P 3 ) consecutively. P 1 and P 3 are stationary, and their polar
explain briefly about piezoelectric effect to produce ultrasonics
If the resultant force acting on a body of constant mass is zero, the body's momentum is: a) Increasing b) Decreasing b) Always zero d) Constant Ans: If
Action and reaction in pushing forces Forces work in pairs. If you push against a wall, the wall pushes with equivalent force back against you. Secure two kitchen spring balanc
Beauty criterion (Dirac) The idea that the more aesthetically pleasant a theory is, the better it is. Of course this criterion does not stand up to the real test whether or no
Advantages of D.C. transmission of power 1. It needs only two conductors as compared to three for a.c. transmission. 2. There is not an inductance, capacitance, phase displ
Describe Kirchoff's Voltage Law? Ans. It describe, " the sum of the Voltage drops around a DC series circuit same to the applied voltage or source. E = E 1 + E 2 = E 3 .
é How many types of breakdown ?
what do you mean by nuclear fusion and fusion? explain briefly giving certain examples.
Can you explain Ohms Law? Ans. If Temperature remains constant then current flow is directly proportional to applied Voltage. I ∝ V, I = V/R (resistance of the conductor)
