Explanation

SQUID stands for Superconducting Quantum Interference Device.

It is an extremely sensitive magnetometer used to detect very weak magnetic fields, such as those produced by brain activity (in magnetoencephalography, or MEG).

It can detect magnetic fields as small as 10⁻¹⁴ tesla, making it ideal for brain studies.

Explanation

 A proton is a fundamental particle found in the nucleus of an atom.

Its mass is relatively large compared to other particles like electrons, but smaller than some other subatomic particles.

Mesons are a type of particle made up of a quark and an antiquark.

Their mass range varies, but generally falls between that of a proton and an electron.

Some mesons, like the very heavy upsilon mesons, can have a mass significantly greater than a proton. 

Explanation

Heat is a form of energy.

SI unit of heat = joule (J)

Work

SI unit = joule (J)

 Same as heat

Explanation

Cornstarch and water form a non-Newtonian fluid called oobleck, which:

• Acts like a liquid when moved slowly
• Acts like a solid when force is applied

Explanation

Explanation

We know that for a Gaussian surface, flux = q/ε

Here, q = 10^-6 C and ε = 8.85 X 10^-12 C/Nm^2

Therefore, flux = 10^-6/8.85 X 10^-12 

= 1.12 X 10^5 Nm^2/C.

Explanation

Rectification: A rectifier is a device that converts alternating current (AC) into a direct current (DC). This process is called rectification.

• A p-n junction can be used as a rectifier because it permits current in one direction only.

Amplification: The process of increasing the amplitude of the sound wave is called amplification.

• In this process, we generally increase the volume of the sound.

Explanation

 in every instant of time, the wavelength associated with a freely falling body decreases.

This is because the de Broglie wavelength 

λ of a particle is inversely proportional to its momentum:

(𝜆=ℎ/𝑝 ).

where:

• $h$ is Planck's constant,
• $p$ is the momentum of the particle.

Explanation

To find the total number of radians through which a point on a wheel has rotated, we can use the fact that one complete revolution corresponds to 2π radians.

For 3 complete revolutions, the total radians can be calculated as follows:

Total radians=Number of revolutions×2π

Total radians=3×2π=6π
