Explanation

• Sound waves first enter the ear through the Ear Canal, also known as the external auditory meatus.
• From there, they travel to the eardrum, then to the cochlea, and finally to the auditory nerve.

Explanation

Volt is the unit of measurement for the potential difference that cause a current to flow through a conductor.  

Explanation

• Silicon is an example of a Semiconductor.
• Semiconductors like silicon have electrical conductivity between conductors and insulators.
• It enabling them to control electrical current flow in devices and integrated circuits.

Explanation

• The pressure exerted by a gas is a result of the countless collisions of gas molecules with the container walls, which transfer momentum.
• It force to the walls, causing pressure.
• This is a fundamental principle in kinetic molecular theory.

Explanation

In most businesses and homes, electrical circuits are connected in parallel to ensure that:

• Each device receives the same voltage
• If one device fails or is turned off, others remain operational
• The entire circuit doesn't fail if one device is disconnected

Explanation

• Whales have a unique audible range that is adapted to their underwater environment.
• They can hear sounds at very low frequencies, often below 20 Hz, and up to 31 kHz.

Explanation

• The Earth rotates on its axis, completing one full rotation in 24 hours.
• This is the equivalent of 1,440 minutes or 86,400 seconds.
• This rotation is what gives us day and night, as different parts of the planet face towards or away from the Sun.

Explanation

• The electric field strength related to Hall voltage is given by VH/d, where V is the Hall voltage and d is the width of the conductor.
• The Hall effect is the production of a potential difference (the Hall voltage) across an electrical conductor that is transverse to an electric current in the conductor and to an applied magnetic field perpendicular to the current.

Explanation

Due to heating, when a free electron is produced than simultaneously a hole is also produced.

Explanation

The postulate that "Collisions of gas molecules are elastic" is not a part of the Kinetic Molecular Theory of Gases.
