An empty vessel is partially filled with water, then the frequency of vibration of air column in the vessel

As an empty vessel in filled with water, its frequency

As an empty vessels is filled with water, its frequency:

In fundamental mode, the time required for the sound wave to reach upto the closed end of a pipe filled with air is 0.01 s . The frequency of vibration of air column is

In fundamental mode, the time required for the sound wave to reach upto the closed end of a pipe filled with air is 0.01 s . The frequency of vibration of air column is

A cylindrical vessel 60 cm in diameter is partially filled with water. A sphere 30 cm in diameter is gently dropped into the vessel and is completely immersed. To what further height will the water in the cylinder rise ?

When temperature of air column bounded by the tube increases , then the frequency of the vibration of air column

The time required for the sound wave to reach up to the closed end of a pipe filled with air medium is 0.02s. What will be the frequency of vibration of air column ?

A piece of ice is floating in a glass vessel filled with water. Then prove that level of water in the vessel remains unchanged after melting of ice.
