Explanation

Coagulation and filtration is one of the most common water treatment techniques used by larger water systems, used for removing particulates and turbidity from surface water.

Explanation

 The temperature coefficient of resistance indicates how the resistance of a material changes with temperature.

In semiconductors, as temperature increases, more charge carriers (electrons and holes) become available, so resistance decreases.

Therefore, the temperature coefficient is negative.

Explanation

When an aldehyde is oxidized, it typically converts to a carboxylic acid.

This reaction involves the addition of an oxygen atom to the aldehyde, changing the carbonyl group (C=O) at the end of the carbon chain into a carboxyl group (–COOH).

Explanation

if the phase of vibration Θ = π/ z radians, and you are saying that a quarter of the cycle is completed

Then we can equate these two conditions to find the value of z.

In Simple Harmonic Motion (SHM), one complete cycle corresponds to 2π radians. Therefore, if  Θ = π/ z radian represented a quarter of the cycle, then we can write:

 Θ = π/ z = 1/ 4 x 2 π

simplifying 

  π/ z =  π/ 2

 Now, to find the value of z, we can cross-multiply

z = 2

So, when the phase of vibration Θ = π/ z radians and a quarter of the cycle is completed, the value of z is 2.

Explanation

Inductance ($L$) is primarily influenced by the following factors:

1. Number of Turns:

   The inductance increases with an increase in the number of turns in the coil. More turns create a stronger magnetic field, which enhances inductance.

2. Area of the Coil:

   The larger the cross-sectional area of the coil, the greater the inductance, as it can enclose more magnetic flux.

3. Length of the Coil:

   The inductance decreases with an increase in the length of the coil. A longer coil has a weaker magnetic field for a given current.

4. Core Material:

   The material around which the coil is wound (the core) affects inductance. Ferromagnetic materials increase inductance due to their higher permeability compared to air or non-magnetic materials.

Explanation

Cations are ions that are positively charged.

Anions are ions that are negatively charged.

Explanation

In an adiabatic process, when the volume of a gas decreases, the temperature of the gas increases.

• In an adiabatic process, no heat is exchanged with the surroundings.
  
• When the volume decreases, the gas is compressed, and work is done on the gas.
• This work increases the internal energy of the gas, which raises its temperature.

Explanation

When two waves of the same frequency and amplitude meet in phase, they align perfectly at their peaks and troughs.

This results in constructive interference, where the amplitudes of the waves add together.
