Which of the following statements are correct?
A. Relative motion between a coil and a magnet induces the electric current.
B. The charges in motion can experience force due to a stationary magnet.
C. Mutual inductance of a pair of coils does not depend on their separation as well as their relative orientation.
D. Self inductance plays the role of inertia.
Choose the correct answer from the options given below:

Two coils have a mutual inductance 0.005 H . The current changes in the first coil according to the equation \(I=I_0 \sin \omega t\), where \(I_0=10 A\), and \(\omega=100 \pi rad / s\). The maximum value of emf in the second coil is (in V) :

In the given setup of meter bridge, the null point D is obtained at a distance of 40 cm from end A. If a resistance of 10 \( \Omega \) is connected in series with \( R_1 \), the null points shift by 20 cm. The values of \( R_1 \) and \( R_2 \) respectively are

In a p-n junction, the magnitude of the drift current is lower than the magnitude of the diffusion current when the junction is

The capacitance of a parallel capacitor plate, when a slab of material of dielectric constant \(k\) having same area as the plates of a parallel plate capacitor but thickness \(\frac{d}{2}\) (where 'd' is the separation of the plates) is inserted between the plates, will be :
(Given \(C _0=\) capacitance of capacitor with air as medium between plates)

Choose the correct statements, when a cell of emf E and internal resistance r connected to external resistance R having current I flowing through the circuit is:
A. Potential difference across the terminals of the cell in a closed circuit having resistance R is always less than the emf.
B. For practical calculations, the internal resistance of the cells in the circuits may be neglected when the current I is such that E >> I.
C. Terminal potential difference in a closed circuit is always more than emf E.
D. Terminal potential difference versus current graph for a cell with closed circuit having resistance R is a straight line with a negative slope.
Choose the correct answer from the options given below:

Electron and Photon have same de Broglie wavelength, which of the following is true for their momentum :

Which of the following is true for the given reaction?
\(\text{CH}_3-(\text{CH}_3)_3\text{C-N-CH}_3 + \text{Cl-SO}_2-\text{C}_6\text{H}_5 \rightarrow \text{No Reaction}\)

Read the following paragraph carefully and answer the given questions.
Certain types of leukocytes (WBC) of our body like polymorpho-nuclear leukocytes (PMNL-neutrophils) and monocytes and natural killer (type of lymphocytes) in the blood as well as macrophages in tissues can phagocytose and destroy microbes. For determining the cause of allergy, the patient is exposed to or injected with very small doses of possible allergens, and the reactions studied. The use of drugs like anti-histamine, adrenalin and steroids quickly reduce the symptoms of allergy. Heroin, commonly called smack is chemically diacetylmorphine which is a white, odourless, bitter crystalline compound. This is obtained by acetylation of morphine. Techniques like radiography (use of X-rays), CT (computed tomography) and MRI (magnetic resonance imaging) are very useful to detect cancers of the internal organs. Different species of Plasmodium (P. vivax, P. malaria and P. falciparum) are responsible for different types of malaria. Of these, malignant malaria caused by Plasmodium falciparum is the most serious one and can even be fatal.
Which one of the following is not the cellular barrier of innate immunity?

The ratio of nuclear densities of two nuclei having mass numbers A and 8 A, respectively is

Identify the correct options with respect to the salient features of DNA.
(A) The two polynucleotide chains are coiled in a left-handed fashion
(B) Adenine forms three hydrogen bonds with thymine
(C) The distance between a base pair in a DNA helix is approximately 0.34 nm
(D) The plane of one base pair stacks over the other in double helix
