If water in one flask and castor oil in other are violently shaken and kept on a table, which will come to rest earlier

Water is taken in one beaker and glycerine in another. Both are stirred well and kept on the table. Which will come to rest first?

Which one yields castor oil ?

A flask contains glycerine and the other contains water. Both are stirred vigorously and placed on the table. In which flask will the liquid come to rest earlier and why?

We have three beakers A , B and C containing glycerine, water and kerosene respectively. They are stirred vigorously and placed on a table. The liquid which comes to rest at the earliest is

A U tube is first partially filled with mercury. Then water is added in one arm and an oil is added in the other arm. Find the ratio of water and oil columns so that mercury level is same in both the arms of U tube. Given : Density of water =10^(3)kg m^(-3) , density of oil =900kg m^(-3) .

A U-tube contains water and oil separated by mercury. The mercury columns in the two arms are at the same level with 10 cm of water in one arm and 12.5 cm of oil in the other, as shown in figure. What is the relative density of oil ?

In Miller’s experiment, He used a mixture of CH_(4) , NH_(3) , H_(2) and water vapour in a closed flask to mimic early earth’s conditions. What was the temperature at which this flask was kept?

A man throw rings into air one after the other at an interval of one second. The next ring is thrown when the velocity of the ring thrown earlier is zero. The height to which the ring rise is ("take" g = 10ms^(-2))

A person invites a group of 10 friends at dinner and sits (i) 5 on a round table and 5 on other round table (ii) 4 on one round table 6 on other round table . Find no. of ways in each case in which he can arrange the guest?

A ball of mass m moving with a velocity v along X-axis, strikes another ball of mass 2m kept at rest. The first ball comes to rest after collision and the other breaks into two equal pieces. One of the pieces starts moving along Y-axis with a speed v_1 . what will be the velocity of the other piece?
