Write an observation if we put three stones as object, a wooden block and an ice cube into the water. Explain it on the basis of Archimedes Principle.

Academic Physics NCERT Class 9

A stone has a higher density than the density of water. Therefore it will sink whereas a wooden block and ice have lower density than that of water therefore they will will float. The observation from given experiment is that objects which have higher density than water will sink and those with lower density will float.

Archimedes' principle states that an object immersed in a fluid is buoyed up by a force equal to the weight of the fluid displaced by the object. The weight of the displaced fluid can be found mathematically. The mass of the displaced fluid can be expressed in terms of the density and its volume, m = ρV.

If a fresh egg is put into a beaker filled with water, it sinks. On dissolving a lot of salt in the water, the egg begins to rise and then floats. Why?
Conversion of ice into water and water into ice is an example of change which can be reversed. Give four more examples where you can say that the changes can be reversed.
A student sets up an apparatus to determine the melting point of ice. He takes a beaker half filled with crushed ice and dips a mercury thermometer with an initial reading of room temperature (25ºC) in such a way that the bulb of the thermometer is surrounded by ice. The correct observation obtained by the student is that :Mercury in the thermometer keeps on falling till it reads, −1ºC and becomes constant thereaftertemperature falls, reaches 0ºC, then it remains constant even after the whole of the ice has meltedthe temperature falls in the beginning but starts rising as soon as the ice starts meltingtemperature falls, reaches 0ºC and remains constant only as long as both ice and water are present in it
Name the principle which gives the magnitude of buoyant force acting on an object immersed in a liquid.
A bullet of mass $10\ g$ traveling horizontally with a velocity of $150\ ms^{-1}$ strikes a stationary wooden block and comes to rest in $0.03\ s$. Calculate the distance of penetration of the bullet into the block. Also, calculate the magnitude of the force exerted by the wooden block on the bullet.
