Explanation

The unit of magnetic flux density is Wb m⁻² (weber per square meter).

It is commonly referred to as a tesla (T), which quantifies the strength of the magnetic field.

Explanation

The induced current will flow in such a direction so as to oppose the cause that produces it is the statement of Lenz's Law.

This law reflects the principle of conservation of energy in electromagnetic induction.

Explanation

In an AC generator, the emf will be maximum when the factor sinωt is equal to 1.

This occurs when the angle is 90°.

This resulting in the peak value of the sinusoidal emf.

Explanation

Electric generators and transformers are based on the principles of Faraday's law.

This law explains electromagnetic induction, where a changing magnetic field induces an electric current.

Explanation

Geometric isomerism is displayed by compounds having the same structural formula but different positions of atoms or groups on either side of a double bond.

It involves Geometric isomerism is displayed by compounds having the same structural formula but different positions of atoms or groups on either side of a double bond.

It involves cis-trans or E-Z isomers.

Explanation

I-Butene and II-Butene show position isomerism.

The double bond is located at different positions in the carbon chain, which distinguishes them.

Explanation

Ions and compounds are colorless is not a property of transition elements.

Transition elements often form colored compounds due to d-d electron transitions, while they also exhibit high melting points.

They are hard metals, and are good conductors of electricity.

Explanation

The electronic configuration of chromium (Proton number 24) is [Ar] 3d⁵ 4s¹.

Chromium exhibits an exception to the standard filling order to achieve a more stable half-filled d-subshell.

Explanation

Graphite is not an alloy; it is a pure form of carbon.

The bronze, steel, and brass are alloys made from a mixture of metals.

Explanation

The solubility of sulfates of alkaline metals generally decreases down the group.

As you move down the group, the lattice energy of the sulfates increases.

This making them less soluble in water.
