Answer: The correct option is A.

Explanation:

Sound is a longitudinal wave. In longitudinal wave, the particles vibrate parallel to the direction of the propagation of the wave.

Sound wave consists of compression and rarefaction.

It needs medium to travel. It can travel in solid, liquid and gas. Denser the medium, more will be the speed of the sound.

Sound wave travels faster in solid in comparison to liquid.

In the given problem, when traveling from air to a solid then the speed of the sound wave will speed up.

Therefore, the correct answer is A.

Which of the following statements are true? The internal resistance of a battery decreases with decreasing temperature. A batter

Eddi Din [679]

Answer:

Option B

Explanation:

The obstruction offered by the battery is known as its internal resistance. Electricity is produced by the chemical reactions inside the battery. The pace of the responses is straightforwardly relative to the temperature and the power delivered by the battery increments. In this way, the inward opposition of the battery increments as diminishing the temperature.
The battery is a gadget which generates electrical energy by the chemical reactions that takes place inside it.

In this way, the announcement a battery is a gadget that produces electricity by the transformation of chemical energy into electrical energy is valid.
The potential difference between the terminals of a battery, when no current is streaming into an outer circuit is called emf of the battery and if the potential distinction is measure when the current is streaming into the outside circuit is called terminal voltage .
The battery attempts to move the negative charge from the low potential terminal to the high potential terminal of the battery. The potential vitality of the negative charges is high at the lower potential terminal and the potential vitality of the negative charge is low at the high potential terminal. Along these lines, the battery attempts to move the charges from high potential terminal to low potential terminal.

The sound waves pass through the door and will then go further from the space near the door making the sound hear outside the door also.

<u>Explanation:</u>

Waves can twist around corners in view of an impact called diffraction. The sum that a wave will twist around a corner as a result of diffraction is about equivalent to its frequency. So it is a lot simpler to see the bowing of the sound waves, since it is around a million times greater than the bowing of the light waves.

As the waves pass through the door, they bend and travel into the space near the door. Because they spread out into the space beyond the door, a person near the doorway can hear sounds from inside the room.
