Explanation

The kinetic energy (KE) of an electron in the nth orbit is given by:

KE = 1/2mv²n

Where m is the mass of the electron and vn is its velocity in the nth orbit.

Explanation

Magnetic induction 𝐵 represents the amount of magnetic flux passing per unit area — hence called magnetic flux density.

It is measured in tesla (T) in the SI system.

Explanation

Carbon monoxide (CO) is a colorless, odorless gas produced by incomplete combustion in gas heaters.

It is highly toxic.

It can cause death when inhaled in large amounts.

Explanation

• Self-Pollination is the transfer of mature pollen grains from the anther of one flower to the stigma of the same flower or another flower of the same plant.
• This means that the pollen is transferred within the same plant, allowing for fertilization to occur without the involvement of another plant.

Explanation

Ozonolysis splits the double bond and gives:

• CH₃CH₂COCH₃ (Butan-2-one)
• CH₃CHO (Acetaldehyde)

These products match the cleavage of 3-methyl-2-pentene at the double bond.

Explanation

Glucose synthesis occurs during photosynthesis, which primarily happens in the leaves.

Leaves contain chlorophyll that captures sunlight energy needed for this process.

Explanation

Bacteria (e.g., Streptomyces) and Fungi (e.g., Penicillium) are commonly used to produce antibiotics.

These microorganisms naturally produce substances that kill or inhibit other microbes.

Explanation

Fe = 56, N = 14 × 2 = 28, O = 16 × 6 = 96 → Total = 56 + 28 + 96 = 180 amu

This is the correct formula mass for Iron (II) Nitrate, Fe(NO₃)₂.

Explanation

A spectrometer is an instrument used to measure the properties of light over a specific portion of the electromagnetic spectrum, especially to analyze line spectra produced by atoms or molecules.

It helps identify elements or compounds by detecting their unique emission or absorption lines in the spectrum.

Explanation

Attrition is the process where rocks and pebbles grind against each other, causing them to wear down.

It occurs mainly in rivers or along the coast due to movement and collision.
