Explanation

A Newton (N) is the unit of force in the International System of Units (SI).

Force (F) is equal to mass (m) times acceleration (a): F = ma.

"That gives a 1 kg body an acceleration of 1 m/s²".

Using F = ma, if m = 1 kg and a = 1 m/s², then F = 1 kg × 1 m/s² = 1 N.

Explanation

When water acts as the solvent in dissolving a substance, the process is called hydration.

It involves the attachment of water molecules to the ions or molecules of the solute.

Explanation

In protozoa, holophytic nutrition (photosynthesis-like) is also referred to as holozoic nutrition when they ingest solid food.

But specifically, holophytic is more similar to autotrophic, and in protozoa, holozoic describes ingestion of food.

Explanation

First polynomial: 8x² + 10x - 25

Second polynomial: 5x² - 9x - 10

(8x² + 10x - 25) - (5x² - 9x - 10)

= 8x² + 10x - 25 - 5x² + 9x + 10

= 3x² + 19x - 15

Explanation

Correct Narration Change:

The original sentence (Teacher said to them, "Don't make noise") is a command (strict instruction).

In indirect speech, "ordered" is the most appropriate verb for strong commands like this.

The imperative "Don’t make noise" changes to "not to make noise" (infinitive structure in reported speech).

Explanation

The phrase "never met him yesterday" is incorrect because "never" (implies at no time in life) and "yesterday" (refers to a specific past time) should not be used together.

Correct sentence: "You are wrong; I met him yesterday." or "You are wrong; I have never met him." (without "yesterday").

Explanation

شیخ ایاز نے شاہ عبد اللطیف بھٹائی کے مجموعہ کلام "شاہ جو رسالو" کا اردو میں منظوم ترجمہ کیا۔

وہ ایک ممتاز اردو و سندھی شاعر تھے جنہوں نے بھٹائی کی فکر کو نئی نسل تک پہنچایا۔

Explanation

Impossible Situation:

Constant velocity requires zero acceleration (Newton’s First Law).

Variable acceleration would imply a changing net force, which must alter velocity (contradicting "constant velocity").

Possible Situations:

Zero velocity, non-zero acceleration:

Example: A ball at the top of its vertical toss (v=0, a=9.8 m/s² downward).

Velocity east, acceleration west:

Example: A car moving east while braking (deceleration acts west).

Velocity east, acceleration east:

Example: A car speeding up in the east direction.

Explanation

These lines are from the poem "The Character of a Happy Life" by Sir Henry Wotton.

The poem describes the qualities of a truly happy and virtuous person.

Explanation

Step 1: Parallel Combination

C_parallel = C + C = 2C

Step 2: Series with Third Capacitor

1/C_eq = 1/2C + 1/C

= (1/2C) + (2/2C)

= 3/2C

C_eq = 2C/3
