Explanation

The pons controls facial expressions, eye movement, and some sensory roles.

It serves as a communication bridge between different parts of the brain.

Explanation

"Will have" is used for future tense to indicate something that will happen soon.

The sentence talks about a future event, so "will have" fits correctly.

Explanation

Sodium nitrate, sodium citrate, and even sodium sulphate (less commonly) are used in preserving food by preventing microbial growth.

These salts help in extending shelf life and maintaining flavor or color in processed foods.

Explanation

Jet engines typically produce very high power, often in the megawatt (MW) range.

1.2 × 10⁶ watts equals 1.2 megawatts, which is appropriate for a jet engine.

Explanation

خراماں خراماں کا مطلب ہوتا ہے آہستہ اور خوبصورت انداز میں چلنا۔

یہ لفظ عموماً شان و شوکت یا آرام دہ انداز کی طرف اشارہ کرتا ہے۔

Explanation

In a reversible adiabatic process, there is no heat transfer (Q = 0).

As a result, the entropy change (ΔS) is zero because entropy change is directly related to heat transfer in a reversible process (ΔS = Q / T).

Explanation

The orbital speed (v) of a satellite is given by:

v = √(GM / (R + h))

If the orbital radius (R + h) is halved:

v' = √(GM / ((R + h) / 2))

= √(2GM / (R + h))

= √2 * √(GM / (R + h))

= √2 * v

So, the orbital speed will increase √2 times.

Explanation

Given:

Magnification M = 5

Distance between lenses L = f₀ + fₑ = 24 cm

Magnification formula M = f₀ / fₑ

Let's solve for f₀ and fₑ:

1. f₀ / fₑ = 5 => f₀ = 5fₑ

2. f₀ + fₑ = 24

Substituting f₀ = 5fₑ into the second equation:

5fₑ + fₑ = 24

6fₑ = 24

fₑ = 4 cm

Now, f₀ = 5fₑ = 5 × 4 = 20 cm

Explanation

The total time of flight (T) for a projectile is given by:

T = 2v₀sin(θ) / g

The maximum height (H) is:

H = (v₀sin(θ))² / (2g)

Using T = 2v₀sin(θ) / g, we can express v₀sin(θ) = gT/2. Substituting this into the height equation gives:

H = (gT/2)² / (2g) = g²T² / 8g = gT² / 8

Explanation

Surprised and Astonished are synonyms — both mean being amazed.

Likewise, Generosity and Magnanimity are synonyms — both mean kindness and nobility of spirit.
