If the linear momentum is increased by $50\%$, then kinetic energy will increase by

If an atom crystallises in bcc lattice with r = 4 $?? then the edge length will be

Consider the system shown in figure. The pulley and the string are light and all the surfaces are frictionless. The tension in the string is (take g = 10 m s)

Best reagent for the conversion of $AgNO_3$ to Ag is

XX-XY type of sex determination mechanism is an example of male heterogamety. In birds, male heterogamety is seen as males produce two different types of gametes.

When acetamide reacts with $NaOH$ and $Br_2$, methyl amine is formed. The reaction occurs through intermediate formation of isocyanate.

When an object is placed between two plane parallel mirrors, then all the images found are of equal intensity. In case of plane parallel mirrors, only two images are possible.

Value of radius of gyration of a uniform rigid body depends on axis of rotation. Radius of gyration is root mean square distance of particles of the body from the axis of rotation.

Staggered conformation of ethane is $12.5\, kJ\, mol^{-1}$ more stable than the eclipsed conformation. The two conformations of ethane cannot be separated at room temperature.

In opposite phyllotaxy two leaves are borne on the opposite sides of a single node. Opposite phyllotaxy is seen in China rose and Oleander.

IgM is a type of immunoglobulin which cannot cross the placenta. IgM is pentamer immunoglobulin, joined by J-chain.

Gap junctions perform cementing function to keep the neighbouring cells together. Tight junctions facilitate the cells to communicate with each other by connecting the cytoplasm of adjoining cells, for rapid transfer of ions, small and big molecules, etc.

Endothecium layer of anther wall plays an important role in dehiscence of anther. The presence of fibrous bands and differential expansion of inner and outer tangential walls of endothecial cells cause dehiscence of anther.

Diamagnetic substances are not attracted by magnetic field. Diamagnetic substances have no unpaired electrons.

Critical temperature of CO is 304 K, it cannot be liquified above 304 K. At a certain temperature, $volume \propto\frac{1}{pressure}$

Consciousness is considered as the defining property of living organisms. All organisms, from the prokaryotes to the most complex eukaryotes can sense and respond to environmental stimuli.

Charcoal is used in separation of noble gases. Charcoal has porous structure.

bond angle is less than the normal tetrahedral bond angle. Lone pair-lone pair repulsion decreases bond angle.

Atmospheric nitrogen gas is always fixed by nitrogen-fixing micro-organisms. Decomposers release nitrogen gas from dead bodies of plants and animals.

At resonance, $LCR$ series circuit have a minimum current. At resonance, in $LCR$ series circuit, the current and e.m.f are not in phase with each other

2-Methyl-1, 3-butadiene is the monomer of natural rubber. Natural rubber is formed through anionic addition polymerisation.

According to Bohr?? theory, which of the following correctly represents the variation of energy and radius of an electron in n orbit of H-atom?

A transistor connected at common emitter mode contains load resistance of 5 k$\Omega$ and an input resistance of 1 k$\Omega$. If the input peak voltage is 5 mV and the current gain is 50, find the voltage gain.

Cornea transplant in humans is almost never rejected. This is because

Pseudostratified epithelium is found in
