A proper combination of \(3 \mathrm{NOT}\) and 1 NAND gates is shown. If \(A=0, B=1, C=1\), then the output of this combination is

An interference pattern is observed by
Young’s double slit experiment. If now the
separation between coherent source is halved and the distance of screen from coherent
sources

A tube of sugar solution \(20 \mathrm{~cm}\) long is placed between crossed nicols and illuminated with light of wavelength \(6 \times 10^{-5} \mathrm{~cm}\). If the optical rotation produced is \(13^{\circ}\) and the specific rotation is $...

In the given figure, \(C\) is middle point of line \(S_1 S_2\). A monochromatic light of wavelength \(\lambda\) is incident on slits. The ratio of intensities of \(S_3\) and \(S_4\) is

The Young's double slit experiment is performed with blue and green light of wavelengths 4360 Å and 5460 Å respectively. If \(x\) is the distance of 4th maxima from the central one, then

Assertion : Corpuscular theory fails in explaining the velocities of light in air and water.
Reason : According to corpuscular theory is that light should travel faster in denser media than rarer media.

The driver of a car travelling with speed \(30 \mathrm{~ms}^{-1}\) towards a hill sounds a horn of frequency \(600 \mathrm{~Hz}\). If the velocity of sound in air is \(330 \mathrm{~ms}^{-1}\), the frequency of reflected sound as heard by dr...

A force \(\mathbf{F}=-k(y \hat{\mathbf{i}}+x \hat{\mathbf{j}})\) where \(k\) is a positive constant, acts on a particle moving in the \(x y\) plane. Starting from the origin, the particle is taken along the positive \(x\)-axis to the point ...

A block is dragged on a smooth plane with the
help of a rope which moves with a velocity v
as shown in the figure. The horizontal velocity

A person of weight \(70 \mathrm{~kg}\) wants to loose \(7 \mathrm{~kg}\) by going up and down \(12 \mathrm{~m}\) high stairs. Assume he burns twice as much fat while going up than going down. If \(1 \mathrm{~kg}\) of fat is burnt on expendi...
