Which of the following statements are correct regarding methods used to remove hardness of water? I. Temporary hardness due to Ca and Mg bicarbonates can be removed by boiling. II. In Clark's process, lime is used to precipitate calcium carbonate. III. Calgon softens water by forming soluble complexes with Ca$^{2+}$ and Mg$^{2+}$.

A compound microscope consists of an objective lens of focal length \( f_{o}=1~\text{cm} \) and an eyepiece of focal length \( f_{e}=5~\text{cm} \). An object is placed 1.2 cm in front of the objective. The final image is formed at the least distance of distinct vision. The nature of the intermediate image and the total magnification of the microscope are:

The unit of rate constant for a first-order reaction is

A wire of length L carrying a current of I ampere is initially bent in the form of a circular coil of one turn. If the same wire is bent into a circular coil of two turns without any change in the current, then the magnetic field at the center of the coil:

A charged particle moves in a region where there is a uniform electric field \[ \vec E = 2\times10^{3}\,\hat i \;\text{N C}^{-1} \] and a uniform magnetic field \[ \vec B = 5\times10^{-2}\,\hat j \;\text{T}. \] The velocity of the particle (in m s\(^{-1}\)) if the particle moves without any acceleration is
