Explanation

You cannot go out because it’s raining very hard.

آپ باہر نہیں جا سکتے کیونکہ بارش بہت سخت ہو رہی ہے۔

The sentence explains why you cannot go out right now, so we need a verb that shows a present continuous action.

“It’s raining” = It is raining → Present continuous tense

It matches the context of an action happening right now.

Explanation

The correct preposition after "justified" when followed by a gerund (verb+ing) is "in."

You are justified in claiming for your rights.

Explanation

The general formula for rotational kinetic energy is:

K.E.=1​/2Iω^2

Where:

• $I$= moment of inertia

• $omega$ = angular velocity

For a hoop (thin ring) of mass
$m$ and radius r:

$I=mr^2$

So, plugging into the formula:

K.E.=1/2⋅mr^2 ⋅ω^2= 1/2​Iω2

Explanation

An alternative unit to kg ms⁻¹ is Ns (Newton-second).

This is because 1 N = 1 kg⋅m⋅s⁻², and multiplying by seconds gives Ns = kg⋅m⋅s⁻¹. 

Explanation

The correct equation representing Heisenberg's uncertainty principle is A) Δx. Δp ≥ ħ/2. 

This equation relates the uncertainty in position (Δx) to the uncertainty in momentum (Δp),

Where "ħ" is the reduced Planck constant. 

Explanation

 Human tissues, particularly in organs like the brain and kidneys, can contain approximately 85% water.

The exact percentage varies by tissue type, but many, especially soft tissues, are largely composed of water.

Explanation

The chemical analysis in which all the elements present in a compound are identified is called qualitative chemical analysis.

This type of analysis focuses on determining the presence or absence of specific elements or compounds within a sample, rather than quantifying their amounts. 

Explanation

 In the sentence:

I met a traveler from an antique land

The word "antique" refers to something very old or ancient, typically from a distant past.

So:

Antique land = Ancient land (a place from ancient history)

Explanation

A body is in translational equilibrium when the vector sum of all forces acting on it is zero, meaning ∑F = 0.

This implies the sum of forces in both the x and y directions are also zero, i.e., ∑Fx = 0 and ∑Fy = 0.

The statement ∑τ = 0 is related to rotational equilibrium, not translational equilibrium.

The condition ∑β = 0 is not standard terminology in physics.

Explanation

 The Calvin cycle is also known as the C3 cycle or the light-independent reactions of photosynthesis.

It can also be referred to as the Calvin-Benson cycle or the reductive pentose phosphate cycle (RPP cycle).
