جسم کا وزن موسم بہار کے توازن کا استعمال کرتے ہوئے ناپا جا سکتا ہے، یہ ______ میں مختلف ہونے کی وجہ سے جگہ جگہ مختلف ہوتا ہے؟
A. Velocity
B. Size of spring balance
C. Acceleration
D. Gravitational pull
Check answer and explanation
Answer: Gravitational pull
Explanation The weight of a body is the force exerted on it by gravity. It depends on the gravitational pull of the planet or moon it is on. Since the gravitational pull varies from place to place (it is stronger near the surface of the Earth than on a mountain, and weaker on the Moon than on the Earth), the weight of a body also varies.
لمبائی، کمیت، برقی رو، وقت، روشنی کی شدت اور مادے کی مقدار _____ کی مثالیں ہیں؟
A. Prefixes
B. Quartile quantities
C. Base quantities
D. Derived quantities
Check answer and explanation
Answer: Base quantities
Explanation These six quantities ( length, mass, electric current , time, intensity of light, and amount of substance) are the fundamental base quantities in the International System of Units (SI). They are the basic building blocks of the SI system and are used to define all other quantities.
فی یونٹ وقت میں کیے جانے والے کام کو ______ کہا جاتا ہے؟
A. Power
B. Energy
C. Efficiency
D. Force
Check answer and explanation
Answer: Power
Explanation Power is the work done per unit time , measured in watts (W). It represents the rate at which energy is transferred or work is done. Additional Information: Efficiency is the ratio of output to input energy. Energy is the ability to do work. Force is a push or pull that can cause an object to change its motion.
کائینیٹک مالیکیولر تھیوری کے مطابق، گیس کے ذریعے ڈالا جانے والا دباؤ _______ کی وجہ سے ہوتا ہے؟
A. Large distances between gas molecules
B. Bombardment of the gas molecules on the walls of the container
C. Random motion of the gas molecules
D. Collision between gas molecules
Check answer and explanation
Answer: Bombardment of the gas molecules on the walls of the container
Explanation According to the kinetic molecular theory , the pressure exerted by a gas is caused by the bombardment of gas molecules on the walls of the container. The gas molecules are in constant motion , colliding with each other and the container walls, resulting in a force exerted on the walls. This force is what we experience as pressure.
Explanation Momentum is the quantity of motion contained in a body. It is defined as the product of an object's mass and velocity . Momentum is a vector quantity and is typically represented by the symbol "p".
پیمائش کا ایک عالمی نظام جس میں بنیادی مقداروں کی اکائیاں متعارف کرائی گئیں ____ کہلاتے ہیں؟
A. International system of units
B. None of above
C. Hexadecimal system
D. Prefixes
Check answer and explanation
Answer: International system of units
Explanation The International System of Units (SI) is a modern metric system that defines the units of measurement for base quantities. Such as length, mass, time, current, temperature , amount of substance, and luminous intensity. The SI system was established in 1960 and is widely used across the world as a standardized system of measurement.
Explanation A solid has a fixed shape and a definite volume , regardless of its container. The particles ( molecules, atoms, or ions ) in a solid are closely packed and have a fixed position, giving the solid its rigidity and shape.
ہیڈ ٹو ٹیل رول کو ______ فورسز کو شامل کرنے کے لیے استعمال کیا جا سکتا ہے۔
A. Three
B. Two
C. Five
D. Any number of
Check answer and explanation
Answer: Any number of
Explanation The head-to-tail rule is a method for adding vectors , such as forces, by lining up the head of one vector with the tail of the next vector. This rule can be used to add any number of forces, not just two or three.
Explanation Specific heat capacity is the thermal energy transfer required per unit mass to increase the temperature of a substance by 1°C (or 1 K). It is a measure of how much heat energy a substance can absorb or release per unit mass per unit temperature change.
جلتی ہوئی موم بتی مادے کی ______ حالت کی ایک مثال ہے۔
A. Solid
B. Liquid
C. All three
D. Gas
Check answer and explanation
Answer: All three
Explanation A burning candle is an example of all three states of matter: Solid : The wax is in a solid state. Liquid : The melted wax is in a liquid state. Gas : The vaporized wax and combustion products are in a gaseous state.
