Explanation

- Capacitance with dielectric: C = εr · C₀, where C₀ is the capacitance without dielectric.

- If the dielectric is removed, capacitance becomes C₀ = C / εr. 

So, the new capacitance is C divided by εr.

Explanation

 Damage to the cerebellum as a result of injury most likely causes poor coordination of movements. 

The cerebellum is primarily responsible for coordinating muscle movements, balance, and fine motor control.

So, damage to this area would lead to clumsiness, an unsteady gait, and difficulty with precise movements. 

Explanation

Water (H₂O) forms strong and extensive hydrogen bonds 

Due to its two hydrogen atoms and two lone pairs on oxygen.

Though HF forms strong individual bonds,

H₂O forms a dense hydrogen bonding network, making its bonding stronger overall.

Explanation

 The charge of cathode ray particles can be determined by passing them through oppositely charged plates. 

Cathode rays are composed of negatively charged particles called electrons.

When these rays pass through an electric field with oppositely charged plates

They are deflected towards the positively charged plate, demonstrating their negative charge. 

Explanation

A biography, or simply a bio, is a detailed description of a person's life.

It involves more than just basic facts like education, work, relationships, and death

Explanation

A generator is a device that converts mechanical energy to electrical energy for use in an external circuit.
A generator works on the principle of electromagnetic induction.

Explanation

Agrostology, the branch of botany concerned with the study of grasses, especially their classification.

Agrostology means مطالعہ گھاس

Explanation

Inertial mass and gravitational mass are Identical in value,

Although they describe different properties of an object and are measured in different ways.

Inertial mass:

measures an object's resistance to acceleration when a force is applied. 

Gravitational mass:

describes how an object interacts with a gravitational field, determining the force it experiences or exerts due to gravity. 

Explanation

The ratio of hydrogen to oxygen by mass in water is always 1:8. 

This ratio is derived from the atomic masses of hydrogen (approximately 1 g/mol) and oxygen (approximately 16 g/mol) in the water molecule (H₂O),

Where there are two hydrogen atoms and one oxygen atom.

Therefore, the mass ratio is (2 * 1) : 16, which simplifies to 2:16 or 1:8. 

Explanation

The pH of acid rain is less than 5.6. 

Normal rain is slightly acidic due to the dissolution of carbon dioxide from the atmosphere.

It forms weak carbonic acid and typically has a pH of around 5.6

When the pH drops below this value, it is classified as acid rain.

Primarily caused by pollutants like sulfur dioxide and nitrogen oxides, according to the EPA.
