Which is quantised in Bohr's atomic model ?

The average power associated with an ideal capacitor of capacitance \( 5 \ \mu\text{F} \) connected to an alternating emf \( E = 200 \sin 100\pi t \) is:

Name the particle 'X' emitted in the nuclear reaction given below -
\( {}_{11}^{22}Na \rightarrow {}_{10}^{22}Ne + \nu + X \)

The deBroglie wavelength of electron when accelerates through potential \(V\) is given by \(\lambda=\frac{h}{\sqrt{x} \sqrt{V}}\) then x is equal to :
where \(m =\) mass of electron
\(k =\) kinetic energy of electron
\(p =\) momentum
e = charge

The electric field E associated with an electromagnetic wave is given by \( E = E_0 \sin(kx - \omega t) \). The speed of the wave is

The frequency of a photon whose energy is 66.3 eV would be (Given \(h = 6.63 \times 10^{-34} \text{ Js}\))

In a plane electromagnetic wave, the electric field oscillates sinusoidally at a frequency of \( 3 \times 10^{10} \text{ Hz} \) and its amplitude is 30 V/m. The amplitude of the oscillating magnetic field is:

Answer the question on the basis of passage given below :
Adsorption is a surface phenomenon and it differs from absorption which occurs throughout the body of the substance that absorbs. In physiosorption the attractive forces are mainly van der Waal's forces while in chemisorption ionic/covalent bonds are formed between particles of adsorbent and adsorbate. The catalytic activity of finely divided iron in Haber's process of ammonia manufacture can be explained by adsorption theory. Adsorption being an exothermic process, the heat of adsorption is utilised in enhancing the rate of the reaction. Adsorption has many applications being used in gas masks, control of humidity, chromatograph separation, curing diseases etc.
The modern adsorption theory lists the following steps for heterogeneous catalysis
(A) Adsorption of reactant molecules on the surface of a catalyst
(B) Occurrence of chemical reaction on the surface of a catalyst
(C) Desorption of products from a catalyst surface
(D) Diffusion of reactants to the surface of the catalyst

Read the passage and answer the question : There are thousands of varieties of rice in India alone. The diversity of rice in India is one of the richest in the world. Basmati rice is distinct for its unique aroma and flavour and 27 documented varieties of Basmati are grown in India. There is reference to Basmati in ancient texts, folklore and poetry, as it has been grown for centuries. Several attempts have also been made to patent uses, products and processes based on Indian traditional herbal medicine, e.g. turmeric, neem. There has been growing realisation of the injustice, inadequate compensation and benefit sharing between developed and developing countries. The Indian Parliament has recently cleared a Bill that takes such issues into consideration, including patent terms emergency provisions and research and development initiative.
One of the classical example of biopatent controversy is of -
