Explanation The average translational kinetic energy of a molecule is given by: (3/2)kT = (3/2) × (1.38 × 10^-23 J/K) × T Since the temperature is the same for both O2 and N2 molecules , the average translational kinetic energy will be the same: 0.048 eV = (3/2)kT The mass of the molecule does not affect the average translational kinetic energy . Therefore, the translational kinetic energy of N2 molecules at the same temperature is also: 0.048 eV
Explanation The period of a physical pendulum can be expressed in different ways, depending on the physical parameters of the pendulum. The physical pendulum is a rigid body that rotates around a fixed axis, and its period is given by: T = 2π√(I/Mgd) : This is the most general expression for the period of a physical pendulum, where I is the moment of inertia of the pendulum about the axis of rotation, M is the mass of the pendulum, g is the acceleration due to gravity, and d is the distance from the axis of rotation to the center of mass of the pendulum. T = 2π√(1/x) : This expression is a simplified version of the previous one, where x = (Mgd)/I. T = √(4L/g) : This expression is applicable when the physical pendulum is a simple pendulum, where L is the length of the pendulum.

Explanation Attock Fort , built during the reign of Akbar from 1581 to 1583 at Attock Khurd. It was constructed to protect the River Indus's passage. It was built under the supervision of Khawaja Shamsuddin Khawafi. The fort features four gates : Delhi Gate , Lahori Gate, Kabuli Gate , and Mori Gate .
ایک مستقل کرنٹ ایک ہیلیکل کنڈلی کے ذریعے خیمہ ہے۔ کنڈلی ______؟
A. Tends to get shorter
B. Produces zero magnetic field at its center
C. None of these
D. Tends to get longer
Check answer and explanation
Answer: Tends to get shorter
Explanation When a constant current passes through a helical coil , it generates a magnetic field along its axis, similar to a solenoid. The electromagnetic forces between the coil’s turns act inward , causing the coil to contract and shorten rather than expand.
Explanation My cat is afraid of dogs and other animals. میری بلی کتوں اور دوسرے جانوروں سے ڈرتی ہے۔ " And " connects two similar ideas . It indicating the cat is afraid of dogs as well as other animals.
اس کی آئنائزنگ پاور ختم ہونے سے پہلے ہوا میں الفا پارٹیکل کے ذریعہ طے شدہ اوسط فاصلہ اس کو کیا کہتے ہیں؟
A. Range
B. Firing level
C. Limit
D. Trajectory
Check answer and explanation
Answer: Range
Explanation The range of an alpha particle refers to the average distance it travels in air before losing all its energy and stopping due to ionization. Alpha particles have high ionizing power but a short range (a few centimeters in air).
انڈس واٹرز ٹریٹی انیس ستمبر انیس سو ساٹھ کو کس نے دستخط کی؟
A. Jawaharlal Nehru and Zulifqar Ali Bhutto
B. Jawaharlal Nehru and Ayub Khan
C. Indira Gandhi and Ayub Khan
D. None of these
Check answer and explanation
Answer: Jawaharlal Nehru and Ayub Khan
Explanation The Indus Waters Treaty, signed on September 19, 1960, Between India and Pakistan Brokered by the World Bank. The Treaty became effective on April 1, 1960. Western Rivers (Indus, Jhelum, Chenab) to Pakistan Eastern Rivers (Ravi, Beas, Sutlej) to India.

زیادہ تر الیکٹرانک آلات میں استعمال ہونے والے مزاحم ______ سے بنے ہیں؟
A. Gold
B. None of these
C. Carbon
D. Rubber
Check answer and explanation
Answer: Carbon
Explanation Carbon resistors are commonly used in electronic circuits because they are cheap, stable, and provide precise resistance values . Other materials like metal film or wire-wound resistors are used for specialized applications, but carbon remains the most widely used.
ایک پوائنٹ چارج سے لامحدود فاصلے پر بجلی کی شدت ______ ہوگی؟
A. Positive
B. Zero
C. None of these
D. Infinite
Check answer and explanation
Answer: Zero
Explanation Electric intensity (electric field) due to a point charge is given by: E = k q/r^2 As the distance r → ∞ (infinite) , the value of 1/ r^2 becomes zero . Therefore, the electric intensity at infinite distance becomes zero . Last updated 14-feb-2026
