The number of ways to select 5 objects from 10 is 10C5 = 10! / (5! * 5!) = 252.

The number of ways to divide 6 people into 2 groups of 3 is 6! / (3! * 3! * 2!) = 20.

The number of arrangements of 7 different items is 7! = 5040.

The number of arrangements in a circle is (n-1)! = 6! = 720.

The word 'LEVEL' has 5 letters with 'L' and 'E' repeating. The arrangements = 5! / (2! * 2!) = 30.

In O2, the π2p orbitals are the highest energy orbitals.

The energy levels of molecular orbitals can vary depending on the specific atoms and their electronegativities.

Nuclear fission releases neutrons along with a significant amount of energy.

In nuclear fission, the primary products are neutrons, which can further induce fission in nearby nuclei.

Nuclear fission primarily produces neutrons along with other fission products.

Nuclear fission releases a significant amount of energy and additional neutrons, which can induce further fission reactions.

Nuclear fusion requires high temperature and pressure to overcome the electrostatic repulsion between positively charged nuclei.

The binding energy is the energy required to remove a nucleon from the nucleus, reflecting the stability of the nucleus.

Total internal reflection in optical fibers minimizes the loss of light as it allows light to be guided through the fiber with minimal attenuation.

Rotational kinetic energy is associated with the rotation of the object in rolling motion.

In SHM, acceleration is maximum at maximum displacement (A).

In SHM, acceleration is maximum at the amplitude (maximum displacement).

The maximum displacement from the mean position in simple harmonic motion is called amplitude.

The maximum speed in SHM occurs at the mean position where the displacement is zero.

The restoring force is directly proportional to the displacement from the mean position.

In SHM, the total mechanical energy is the sum of kinetic and potential energy, which remains constant.

In simple harmonic motion, the velocity is maximum at the mean position where the displacement is zero.

'dl' represents the infinitesimal length of the wire segment that contributes to the magnetic field at a point.

The energy of an electron in the nth level of hydrogen is given by E_n = -13.6 eV/n². For n=2, E_2 = -13.6 eV/2² = -3.4 eV.

The radius of the first orbit in the Bohr model is 0.529 Å or 0.0529 nm.

Nickel in [Ni(CO)4] undergoes sp3 hybridization as it forms four sigma bonds with CO ligands.

Saturation refers to the complete coverage of the adsorbent surface by the adsorbate.

Angular width refers to the angle between the first and second minima in a diffraction pattern.

Coherence refers to the ability of waves to maintain a constant phase relationship, which is essential for producing clear interference patterns.

Resolution refers to the ability to distinguish between two closely spaced objects, which is affected by diffraction.
