Lab Activity: To Determine the Velocity of Sound in Air at Room Temperature Using a Resonance Tube

In the experiment to determine the velocity of sound in air using a resonance tube, which precaution is crucial to ensure proper resonance conditions and accurate measurements?

Which one of the following is not a correct precaution to be taken during finding the specific heat capacity of a solid?

Which one of the following statements is true while using the physical balance for finding the specific heat capacity of a solid by using the principle of mixtures?

Which one of the following is a correct statement for taking the temperature of the mixture after putting the solid in the water filled inside the calorimeter?

The heat given by solid is taken by which one of the following? 

For measuring the temperature of the solid, what should be the position of the thermometer in the experiment for finding the specific heat capacity of the solid?

The mass of the empty calorimeter is $m_1$. When it is filled with water its mass becomes $m_2$. A heated solid of mass  $m_3$ is dipped in the water filled in the calorimeter. The initial temperature of the water is $t_1$, the temperature of the heated solid is $t_2$ and that of the mixture is $t_3$.  If the specific heat capacity of water is $s$ and that of the calorimeter is $s_1$ then which one of the following formulae can be applied to find the specific heat capacity of the solid$\left(s_{\circ }\right)$?

To find the second resonance position, what is the possible change in the position of the reservoir?

Which one of the following precautions is not correct while resonating the air column of the resonance tube?
