Explanation

Servant means نوکر

Explanation

The word “that” is incorrect here; it should be “it”.

Correct sentence: “Sometimes it is difficult to place Physics & Chemistry into separate categories.”

Explanation

Explanation

A Wheatstone bridge is an electrical circuit designed to measure unknown resistance accurately.

It works by comparing it with the known resistances in a balanced condition.

Explanation

The Doppler effect is applicable to all types of waves, including sound waves, light waves, and even water waves.

It describes the change in frequency or wavelength of a wave when there is relative motion between the wave source and the observer.

Explanation

According to Newton's 2nd Law, a constant force on a body produces a constant acceleration proportional to the force and inversely proportional to the mass.

The body does not move with uniform velocity unless the net force is zero.

Explanation

The SI unit of temperature as per the International System of Units is Kelvin.

It is represented by the symbol  K.

Note:

Celsius is currently a derived unit for temperature in the SI system, Kelvin is the base unit.

Explanation

In uniform velocity, distance increases linearly with time.

Hence, the distance–time graph is a straight line with constant slope.

Explanation

Newton's first law of motion is also called as Law of inertia.

• Inertia is the ability of a body by virtue of which it opposes a change.
  
• According to Newton’s first law of motion, an object will remain at rest or in uniform motion in a straight line
• unless acted upon by an external force.
  • The inertia of rest: When a body is in rest, it will remain at rest until we apply an external force to move it. This property is called inertia of rest.
  • The inertia of motion: When a body is in a uniform motion, it will remain in motion until we apply an external force to stop it. This property is called inertia of motion.

Explanation

An isochoric process occurs at constant volume, meaning the system’s volume does not change.

In this process, any heat added changes only the internal energy and pressure, not the volume.
