جسم کے خلیات جو بڑھوتری، مرمت اور ترقی کے لیے تقسیم ہوتے ہیں اسے کیا کہا جاتا ہے؟
Meiosis
Mitosis
Microsis
Mekosis
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Mitosis is the process by which a single cell divides to produce two identical daughter cells . It is essential for growth, tissue repair, and development in multicellular organisms. Mitosis maintains the same number of chromosomes in each new cell. Additional information :
Meiosis is different; it occurs in sex cells and reduces chromosome number by half. Last verified on 10-03-2026

Explanation
Car brakes are typically hydraulic systems , not pneumatic systems. The examples of pneumatic systems :
Spray gun: uses compressed air to atomize and spray paint or other materials. Bicycle pump: uses compressed air to inflate tires. Vacuum cleaner: uses compressed air to create suction and lift dust and debris. Last verified on 09-03-2026
جب ایک مائع کو ایک کنٹینر میں رکھا جاتا ہے، کنٹینر کی طرف سے مائع پر لگایا جانے والا دباؤ پورے کنٹینر میں برابر ہوتا ہے یہ _____ کا بیان ہے؟
Archimedes' Principle
Bernoulli's Principle
Boyle's Law
Pascal's Law
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Pascal's Law states that the pressure applied to a fluid (liquid or gas) in a container is transmitted equally throughout the fluid and to the walls of the container, and that the pressure is the same in all directions at a given point in the fluid. This principle has numerous applications in engineering, physics, and everyday life. Last verified on 09-03-2026
کیمیائی رد عمل کے بارے میں کون سا بیان غلط ہے؟
States of matter does not change during chemical reactions
Chemical reactions produce new substances
Chemical reactions occur with the absorption or emission of energy
Chemical reactions may be fast, moderate or slow
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The incorrect statement is : States of matter does not change during chemical reactions.During chemical reactions , states of matter can change. For example, a solid may dissolve in a liquid , a liquid may vaporize, or a gas may condense into a liquid. Last verified on 09-03-2026
مندرجہ ذیل میں سے کون سی کیمیائی تبدیلی نہیں ہے؟
Melting of ice
Burning of fuel
Explosion of firework
Cooking raw food
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Melting of ice is a physical change , as it only involves a change in state (from solid to liquid) without a change in chemical composition. The examples of chemical changes:
Burning of fuel Explosion of firework Burning of wood Cooking of food (breakfast, lunch, dinner) Bursting of crackers Burning of wax Rusting of iron Heating sulphur with iron fillings (to produce iron sulphide) Digestion of food Respiration in living things Photosynthesis in plants Last verified on 09-03-026

ویکٹر کی مقدار میں میگنیٹیوڈ اور یونٹ کے ساتھ _____ ہوتا ہے۔
Magnitude
Direction
Both a and b
None of them
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Definition: Possess both magnitude and direction.
Representation : Represented by arrows, where the length indicates magnitude and the arrowhead indicates direction.
Examples:
Displacement Velocity Acceleration Force Momentum
Additional information
Difference from Scalars: Unlike scalars, which only have magnitude (e.g., speed), vectors require both to be fully defined

کون سی ایک ویکٹر کی مقدار ہے؟
Mass
Weight
Time
Temperature
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Weight is a vector quantity Because it is a force defined as the product of mass and the acceleration due to gravity ( W = mg). It has both magnitude (amount of force) and direction (downward, towards the center of the Earth) Additional information
Mass, Time, and temperature are scalar quantities
