Explanation

The next term in the series A, BB, CCC, DDDD is EEEEE.

The pattern involves repeating the next letter of the alphabet the corresponding number of times:

A is the 1st letter and appears once;

BB are the 2nd letters and appear twice;

CCC are the 3rd letters and appear thrice;

DDDD are the 4th letters and appear four times

Therefore, the next term should be the 5th letter of the alphabet, E, repeated five times. 

Explanation

Torricelli's theorem is specifically used to find the velocity of efflux.

It states that the velocity of fluid flowing out of an opening (such as a small hole in a container) can be found using the equation:

v=  under root 2gh

where:

 𝑣 is the velocity of efflux,

𝑔  is the acceleration due to gravity (approximately 9.81 m/s²),

ℎ  is the height of the fluid above the opening.

This theorem is particularly useful in situations involving the flow of liquids through openings or nozzles.

Explanation

 The amount of heat required to vaporize one mole of a liquid at its boiling point is called Molar heat of vaporization. 

"Molar" refers to one mole of a substance, and "vaporization" means the process of turning a liquid into a gas. 

Explanation

Tehran is the capital of Iran

Riyadh is the capital of Saudi Arabia.

Explanation

The substance with the most moles is 3.8 g of H2O (0.211 moles).

Therefore, it has the largest number of molecules.

Explanation

Positions in alphabet:  

B = 2  

D = 4  

H = 8  

M = 13  

Find the pattern of differences:  

4 - 2 = 2  

8 - 4 = 4  

13 - 8 = 5  

Differences are: 2, 4, 5 — no obvious sequence, but let's check cumulative sums or pattern in jumps.

Try checking the next letter after M (13):

If we check the difference increasing by 1 or 2, try next difference as 6 or 7.

13 + 6 = 19 → S  

19 + 7 = 26 → Z  

S (19) and Z (26) are letters. So the next two letters are likely S, Z.

Explanation

The next term in the series 3C, 5E, 7G, 9I, 11K, is 13M.

Numbers: 3, 5, 7, 9, 11, ... (increasing by 2 each time)

- Letters: C, E, G, I, K, ... (each letter skips one in the alphabet: C(3), E(5), G(7), I(9), K(11), M(13))

Explanation

34 (3,4) and 58 (5,8) → 4 5 8 3 → matches  

25 (2,5) and 74 (7,4) → 5 7 4 2 → matches  

Apply the same for 47 × 83 (4,7 and 8,3):  

Second digit of first number = 7  

First digit of second number = 8  

Second digit of second number = 3  

First digit of first number = 4  

So answer = 7 8 3 4 → 7834

Explanation

The actual color of the sky is blue, but according to the code:

- Blue is Green

So, if the sky is blue, then in this coded language, its color is Green.
