ایک برقی فیلڈ سب سے زیادہ براہ راست _____ سے متعلق ہے؟
The force acting on a test charge
The momentum of a test charge
The kinetic energy of a test charge
None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The electric field (E) is defined as the force (F) experienced per unit positive test charge (q), i.e. E = F/q.
Hence, it is directly related to the force acting on a test charge .
آواز میں روشنی سے مختلف ہے یہ آواز _____؟
Is a longitudinal wave rather than a transverse wave
Is not subject to diffraction
Does not require energy for his origin
None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Sound travels as a longitudinal wave, where particles vibrate parallel to the direction of wave motion.
In contrast, light is a transverse wave, with vibrations perpendicular to the direction of propagation.
6800 N
12800 N
1090 N
None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Given: Mass (m) = 1000 kg
Acceleration (a) = 3 m/s² (upward)
Gravitational acceleration (g) = 9.8 m/s²
Tension (T) = m(g + a)
= 1000 × (9.8 + 3)
= 1000 × 12.8
= 12,800 N
مندرجہ ذیل میں سے کون تیز رفتار حرکت کی مثال نہیں ہے؟
A swinging pendulum
Horizontal component of projectile motion
Vertical component of projectile motion
Circular motion at constant speed
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The horizontal component of projectile motion has constant velocity ( no acceleration ).
The vertical component and circular motion both involve acceleration, as does a swinging pendulum .
مندرجہ ذیل میں سے کون سا عناصر لینتھانائڈ ہے؟
Polonium (Po)
Actinium (Ac)
Francium (Fr)
Cerium (Ce)
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Lanthanides are a series of chemical elements with atomic numbers from 58 (Cerium) to 71 (Lutetium).
Cerium (Ce) has an atomic number of 58 , making it the first element in the lanthanide series .
مندرجہ ذیل میں سے کون سا حل زیادہ تیزابیت کا حامل ہوگا؟
pH = 1
pH = 2
pH = 6
pH = 1.5
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The pH scale measures the acidity or alkalinity of a solution on a scale from 0 to 14.
Solutions with a pH less than 7 are considered acidic .
The closer the pH value is to 0 , the more acidic the solution is.
Therefore, a solution with a pH of 1 is more acidic .
قدرتی گیس _____ پر مشتمل ہے؟
Methane
Ethane
Propane
All of them
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Natural gas is a mixture of several gaseous hydrocarbons .
The primary component is methane (CH4), which can make up 70% to 90% of the mixture.
Smaller amounts of other hydrocarbons, such as ethane (C2H6), propane (C3H8), and butane , are also present.
These are often referred to as Natural Gas Liquids (NGLs).
They are separated from the methane during processing.
وہ مرکبات جن میں ان کے انو میں کم از کم ایک بینزین رنگ ہوتا ہے اسے _____ کہا جاتا ہے؟
Alicyclic compounds
Aliphatic compounds
Aromatic compounds
None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The compounds that contain at least one benzene ring are called aromatic compounds.
This class of organic compounds , also known as arenes .
It has a unique stability due to a ring of delocalized pi electrons .
