دباؤ کی ایس آئی یونٹ کیا ہے؟
Henry
Pascal
Joule
None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Pressure can be defined as the force acting per unit area. The unit of pressure is N/m² ( Newton per square meter ). It is also called Pascal (Pa) . In SI base units kg⋅m−1⋅s−2 Derivations from other quantities: p = F / A Dimension unit: M L^−1 T^-2 .Additional information
The SI unit of energy/work is the joule (J)
The SI unit of charge is Coulomb
The Pascal is the SI-derived unit of pressure
The ampere, symbol A , is the SI unit of electric current.
The SI unit of power is the watt, one joule per second.
The SI unit of electric resistance is the ohm (Ω).
The SI unit of temperature as per the International System of Units is Kelvin
Unit of torque: newton metre ( N m )
The SI unit of velocity is a meter per second (m/s).
The SI unit of acceleration is meters/second2 (m/s2)

Torque is measured in candela
Torque and candela are unrelated physical quantities.
Torque is directly proportional to candela.
Torque is inversely proportional to candela.
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Torque and candela measure completely different physical quantities .
Torque (τ) is the rotational equivalent of force: τ = Force × Lever arm .
Its SI unit is Newton-meter (N·m) .
Candela (cd) is the SI unit of luminous intensity (brightness of light).

آواز کی لہریں ______ تابکاری ہیں۔
Longitudinal
Electromagnetic
Latitudinal
None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Sound waves require a medium (air, water, or solid) to travel, so they are mechanical waves .
The particles of the medium vibrate parallel to the direction of wave propagation.
This makes sound waves longitudinal waves .
In a longitudinal wave, compressions and rarefactions carry the sound energy.
Therefore, sound waves are mechanical longitudinal waves and cannot travel in a vacuum .

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

کوولینٹ بانڈ دو _____ کے درمیان تشکیل پایا ہے؟
Non-metals
Metalloids
Metals
None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
A covalent bond is formed between two non-metal atoms. Examples: Molecule formation like H₂O and CO₂. Properties: Generally results in lower melting/boiling points compared to ionic compounds. These atoms achieve stability by sharing one or more pairs of valence electrons to fill their outer shells
