Explanation

"Damnation means لعنت" means eternal punishment or being condemned

Condemnation means مزمت

Explanation

For 2p orbitals, the principal quantum number (n) is 2.

The azimuthal quantum number (l) for a p-orbital is 1.

So, n = 2, l = 1 is correct.

Explanation

Haustoria are specialized structures produced by parasitic fungi.

They penetrate the host cells and absorb nutrients directly from the cytoplasm. 

Explanation

I hope they will not have left the city before I reach there.

مجھے امید ہے کہ میرے وہاں پہنچنے سے پہلے وہ شہر چھوڑ کر نہیں گئے ہوں گے۔

The sentence talks about a future action ("before I reach there") 

Future completed action is the future perfect:

will not have + past participle

"Will not have left" shows:

A completed action in the future

That you hope they are still there when you arrive

Explanation

To prepare 250 cm³ (or 250 mL) of a 1 M NaOH solution, you need 10 grams of NaOH.

This is because the molar mass of NaOH is 40 g/mol, and a 1 M solution contains 1 mole of solute per liter of solution.

Therefore, 250 mL (0.25 L) of a 1 M solution would require 0.25 moles of NaOH, which translates to 10 grams (0.25 moles * 40 g/mol). 

Explanation

A carburetor uses the principle of Bernoulli's equation, which states that as the speed of a fluid increases, its pressure decreases.

In a carburetor, air flows through a constricted section called a venturi.

This increased airflow creates a lower pressure area, which then draws fuel from the fuel reservoir into the air stream, effectively mixing them. 

Explanation

Kinetic energy (KE) is expressed as: 

KE = 1/2 * mv² 

Where: m = mass (dimensions: M¹), v = velocity (dimensions: L¹T⁻¹), and v² = (L¹T⁻¹)² = L²T⁻². 

Therefore, the dimensions of KE are: 

KE = M¹ * (L²T⁻²) = M¹L²T⁻² 

Explanation

The pH of a mixture of CH₃COONa (sodium acetate) and CH₃COOH (acetic acid) is C. <7. 

This mixture forms a buffer solution, where the weak acid (CH₃COOH)

Its conjugate base (CH₃COO-) is present together, resulting in a pH that is less than 7 (acidic) but not extremely so

Explanation

 "Screamed" means to yell or cry out loudly, often due to fear, anger, or excitement.

The best synonym is Yelled چیخنا

Explanation

Angular frequency (ω) measures how quickly something moves through an angle in circular motion.

It's given by:

$$omega = frac{2pi}{T} = 2pi f$$

Where:

• $T$ = time period

• $f$= frequency

While it’s also used in oscillations, it is fundamentally defined from circular motion.
