Explanation

Lenz's law states that the direction of induced current in a closed loop is such that it opposes the change in magnetic flux that produced it.

This means that if the magnetic field through a loop increases, the induced current will flow in a direction that creates a magnetic field opposing that increase, and vice versa.

Explanation

Hess's law states that the total enthalpy change of a reaction is the same, regardless of the number of steps in which the reaction occurs, allowing ∆H to be measured indirectly.

Explanation

The noble-gas notation [Kr] is for krypton, and Zr (Zirconium) follows krypton in the periodic table with the configuration 5s², 4d².

Explanation

The Zeeman effect refers to splitting spectral lines when atoms are subjected to a magnetic field.

Explanation

The alkaline mucus secreted by the Cowper's glands also plays an important role in neutralizing the acidic nature in the urine.

Explanation

Sugarcane primarily contains sucrose, which is a disaccharide made up of glucose and fructose.

It is the main sugar extracted from sugarcane.

Explanation

Relative permittivity is the ratio of a medium's is defined by:

1. The ratio of the electric field in vacuum to the electric field in the medium

and

2. The ratio of the capacitance with the medium to the capacitance with air

Explanation

A single chlorine-free radical (Cl•) can destroy up to 100,000 ozone (O₃) molecules. This significant impact on ozone is due to the catalytic nature of chlorine in the ozone depletion process.

Explanation

Apart from the sign,

the magnification factor, m, is equal to i/o

"I" is the image distance from the lens 

"o" is the object distance.

we have m=i/o

(8cm) / (20cm)

= 2/5.

Explanation

Anions are negatively charged ions.

They are formed when non-metal gains electrons.

They gain one or more than one electron.

Therefore, they possess a net negative charge.

____

Cations are ions that are positively charged
