When a deuteron is bombarded on \(^{16}_{8}\text{O}\) nucleus, an α-particle is emitted. Other product nucleus is:

When a semiconductor is doped with a donor impurity

If the magnetic flux through a coil of 1200 turns increases from zero to \(5.4 \times 10^{-5} \text{ Wb}\) in \(2.7 \text{ ms}\), what is the magnitude of the induced emf during this time?

Two wires A and B of the same material and same mass have radii 2r and r, respectively. If the resistance of wire A is \( 4 \, \Omega \), then resistance of B will be

A negatively charged object A is repelled by another charged object B. However, an object C is attracted to object B.
Which of the following is the most probable for the charge of object C?

In a series L, C and R circuit with an ac source of frequency \( \omega \), the current leads the voltage by \( \pi/4 \). The value of capacitance C will be

A current I flows in a circular loop of radius R. The magnetic field at a point on its axis at distance r from the center of the loop is

Sometimes the change in allele frequency is so different in the new sample of the population in which they become a different species. This phenomenon is known as

The electric field vector \( \vec{E} \) and magnetic field vector \( \vec{B} \) in electromagnetic waves are :

The atomic mass unit (1u) is correctly represented by :

Read the Passage carefully and answer the Questions:
Kinetic studies not only help us to determine the rate of a chemical reaction but also describe the conditions by which the reaction rates can be altered. The factors such as concentration, temperature, pressure and catalyst affect the rate of a reaction.
The speed of a reaction or the rate of a reaction can be defined as the change in concentration of a reactant or product in unit time.
Rate \(=k[A]^{ a }[B]^{ y }\)
Here \(k\) is the rate constant
\(x+y\) gives the overall order of a reaction, whereas \(x\) and \(y\) represent the order with respect to the reactants \(A\) and \(B\), respectively.
The unit of rate constant for first order reaction is:

When \(1.5\) g of a non-volatile solute is dissolved in \(30\) g of a solvent, the boiling point of the solvent is raised by \(2\ K\). Calculate the molar mass of the solute, given that \(K_b\) for the solvent is \(1.85\ K\ kg\ mol^{-1}\).

Which one of the following is not an example of alien species invasion?
