Hence, the correct answer is "Flute". The guitar is of Western origin, has 6 strings, is plucked or strummed, and is not used in Indian music.

A potentiometer is an accurate and versatile device to make electrical measurements of emf because the method involves a condition of no current flow through the galvanometer, the device can be used to measure potential difference, internal resistance of a cell and compare emf's of two sources. Q.

The Degree of dissociation does not depend on catalyst.The equivalent conductivity of 0.1M weak acid is 100 times less than that at infinite dilution.

Strong electrolytes have a degree of dissociation close to one, while weak electrolytes have a degree of dissociation less than one. Solvent nature: Solvents with a high dielectric constant show more dissociation. Dilution: As the solution is diluted, the degree of dissociation increases.

Explanation: Since polar satellites orbit close to the surface of the earth, it is easier to click images of the planet's surface with greater detail. Their high orbital velocity enables them to view most of the surface strip-by-stip very quickly with which high-resolution images can be constructed.

Explanation: Most communication waves cannot transmit data accurately over long distances due to the curvature of the earth. They can only do so in the line of sight. However, they are not reflected by the ionosphere like radio waves and can be relayed to a wide area using geostationary satellites.

radius of its orbit will become half.

A real gas can behave as an ideal gas if volume of molecule is negligible and interaction between molecule is negligible. This will happen if number of molecule per unit volume is very small. This is only possible at high temperature and low pressure.
