How does the resistance of a metallic wire depend on the thickness of wire?

A given wire is stretched to double its length. How will its resistance change?

In the figure below, the ammeter A reads 0.3 A. Calculate:
(i) the total resistance of the circuit
(ii) the value of R
(iii) the current flowing through R.

Calculate equivalent resistance in the following cases:

Name the subjective property of light related to its wavelength.

How does frequency affect a musical sound?

Name the factors which determine the loudness of a note.

Name the factors which determine the pitch of a note.

Name the factors which determine the quality of a note.

How can one distinguish the sounds of two musical instruments even if they are of the same pitch and same loudness?

How do you account for the fact that two strings can be used to give notes of the same pitch and loudness but of different quality?

The same musical note when played on a piano and when played on a flute sounds different.

Name one main factor on which each character such as intensity, pitch, and quality of musical sound depends.

When a gun is fired at a distance, why is it that the flash is seen almost instantaneously while the sound is heard a little later?

Which characteristics of sound will change if there is a change in its amplitude and its waveform.

How is it possible to detect the filling of a pitcher under a tap by hearing its sound at a distance?

Three musical instruments give out notes at the frequencies listed below. Flute: 400 Hz; Guitar: 200 Hz; Trumpet: 500 Hz. Which one of these has the highest pitch?

What is the noise? Give an example.

What is meant by the ‘pitch’ of a note? Does it depend on the loudness or ‘quality’ of the ‘note’? How is pitch ‘related’ with frequency?

What is meant by the ‘loudness’ of a sound? How is it related to the intensity?
