Explanation

In this series, each number is repeated,

then 13 is subtracted to arrive at the next number.

Rule = (1st number) (1st number) (1st number - 13 = 2nd number) (2nd number repeat) (2nd - 13 = 3rd number) (3rd number repeat)....

The series is 53, 53, 40, 40, 27, 27...

(53),(53 - 13 = 40), (40), (40 - 13 = 27) (27), (27 - 13 = 14), (14)...

So the answer is 14.

Explanation

It's a simple concept

63= 6–3=3

44= 4–4=0

91= 9–1=8

The series is 63,3,44,0,91,8

Explanation

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.
