Explanation

The escape velocity of a body in the gravitational field of Earth is primarily dependent on the mass of the Earth and the radius of the Earth.

It does not depend on the mass of the body or the angle at which it is thrown.

The formula for escape velocity 𝑣e is given by:

Explanation

Given the conditions:

a>b

b>c

d>a

We can draw the following relationships:

From a>b and b>c, we know that a>c.

From d>a, we know d>a and, since a>b and a>c, it follows that d>b and d>c.

So, the only valid option is b

Explanation

Vacuum distillation is used to distill substances at lower temperatures by reducing the pressure, which lowers the boiling point of the substances.

Explanation

One Coulomb (C) is the unit of electric charge and is defined as the amount of charge transported by a steady current of 1 Ampere (A) flowing for 1 second.

Mathematically: 

1Coulomb=1Ampere×1second

This means that if a current of 1 Ampere flows through a conductor for 1 second, the total charge transported is 1 Coulomb.

Explanation

Potassium ferrocyanide ​ [K[Fe(CN) 6] is an example of a complex salt

Because it contains a central metal atom (iron) bonded to ligands (cyanide ions)

Explanation

A carbocation is a carbon atom with a positive charge attached to three other atoms or groups.

Explanation

The reactivity of aldehydes towards nucleophilic addition depends on the size of the alkyl group attached to the carbonyl carbon.

Formaldehyde (HCHO) has no alkyl groups attached to the carbonyl carbon, making it the most reactive

Because there is no steric hindrance, and the electron-donating effect is minimal.
