Explanation

 When a rigid body rotates around a fixed axis, all points on the body have the same angular speed, but not the same linear speed.

The linear speed of a point is directly proportional to its distance from the axis of rotation; points farther from the axis move faster

Explanation

• The Pakistan Space and Upper Atmosphere Research Commission (SUPARCO) was established in 1961.
• It was originally formed as a Committee in 1961 and gained Commission status in 1981.
• The SUPARCO is Pakistan's national space agency and is responsible for the development of space technology and its peaceful applications in the country.
• It is headquartered in Islamabad and has technical facilities in Karachi, Lahore, Multan, Quetta, Peshawar and Gilgit.

Explanation

A capacitor consists of two conductors separated by a non-conductive region.

It stores electrical energy in an electric field between the conductors.

Explanation

The presence of a dielectric material between the plates of a capacitor reduces the electric field by a factor called the dielectric constant 𝐾

The electric field E in a capacitor with a dielectric is related to the field E0 without the dielectric by:

E= E0/K

​When the dielectric material is removed, the dielectric constant K becomes 1 (for vacuum or air), and the electric field reverts to its original strength, increasing by a factor of 𝐾

Thus, when the dielectric is removed, the electric field increases.

Explanation

The quantity known as the equivalent resistance indicates the total resistance of the circuit.

It combines the effects of all resistors in the circuit into a single, overall resistance value.

Explanation

 Titan is the second-largest moon in the solar system,

Largest moon in the solar system is Jupiter's moon Ganymede.

It's larger than the planet Mercury and Earth's moon. 

Explanation

• In a mercury thermometer, the mercury in the bulb expands and rises in the tube, which has a linear scale ranging from 94°F to 108°F.
• This specific range is commonly used for medical thermometers to measure human body temperature.

Explanation

• The Second is a fundamental unit of time in the International System of Units (SI).
• It is one of the seven base units that are used to derive all other units.

Explanation

• Measurement involves comparing an unknown quantity (the measured) with a standard quantity (the unit) to determine its value.
• This process is a fundamental aspect of science and engineering, allowing us to quantify physical properties and phenomena.
