221. The zeroth law of thermodynamics allows us to define _____?

تھرموڈینامکس کا زیروت قانون ہمیں _____ کی وضاحت کرنے کی اجازت دیتا ہے؟

Check answer and explanation

Answer: Temperature

Explanation The zeroth law of thermodynamics states that if two systems are each in thermal equilibrium with a third system, they are in equilibrium with each other . This principle allows the definition of temperature as a fundamental property that determines thermal equilibrium.

222. If a spherical ball rolls on a table without slipping, the fraction of its total energy associated with rotation is ______?

Check answer and explanation

Answer: 2/7

Explanation When a spherical ball rolls without slipping: Total energy (E) = Kinetic energy (K) + Rotational energy (U) K = (1/2)mv^2 U = (1/2)Iω^2 = (1/5)mv^2 (for a sphere) E = K + U = (1/2)mv^2 + (1/5)mv^2 = (7/10)mv^2 Fraction of energy associated with rotation: U/E = ((1/5)mv^2) / ((7/10)mv^2) = 2/7

223. The Antonym of Intransigent is?

Check answer and explanation

Answer: Flexible

Explanation Intransigent means غیر متزلزل Flexible means لچکدار

224. Follow hot on the heels of means?

Check answer and explanation

Explanation " Follow hot on the heels of " means to occur immediately or very soon after something. It implies a quick succession of events.

225. Repeatable entity of a crystal structure is known as?

ایک کرسٹل ڈھانچے کی دہرائی جانے والی ہستی کے نام سے جانا جاتا ہے؟

Check answer and explanation

Answer: Unit cell

Explanation The repeatable entity of a crystal structure is known as a " unit cell ."

226. The substance which shows practically no elastic after effect is _______?

وہ مادہ جو عملی طور پر کسی لچکدار کو ظاہر کرتا ہے وہ _____ ہے؟

Check answer and explanation

Answer: Quartz

Explanation Quartz exhibits almost no elastic after-effect. This meaning it quickly returns to its original shape after deformation. Rubber and silk exhibit significant elastic after-effects. This meaning they take time to return to their original form.

227. Which is an alteration in the observed frequency of a sound due to motion of either the source or the observer?

ذریعہ یا مبصر کی حرکت کی وجہ سے آواز کی مشاہدہ شدہ فریکوئنسی میں کون سا ردوبدل ہے؟

Check answer and explanation

Answer: Doppler effect

Explanation The Doppler effect refers to the change in observed frequency of a sound when the source or observer is in motion. It causes the frequency to increase as they move closer and decrease as they move apart.

228. In rotational motion, the analog of force is ______?

گھومنے والی حرکت میں ، طاقت کا ینالاگ ______ ہے؟

Check answer and explanation

Answer: Torque

Explanation In rotational motion , torque is the rotational analog of force in linear motion. Just as force causes linear acceleration (Newton's Second Law: F = ma ). Torque causes angular acceleration ( τ = Iα ), where τ is torque, I is the moment of inertia, and α is angular acceleration.

229. The Antonym of Filthy is?

Check answer and explanation

Answer: Clean

Explanation Filthy means غلیظ Clean means صاف Last verified on 09-02-2026

230. Antonym of Heartfelt

کا متضادHeartfelt
