Tell me the answer quickly. If the medicine goes inside the skin then why doesn't the water go inside #shorts #ytshorts

Does the value of g change while going deep inside the earth ? Why ?

A small air bubble of radius r in water is at depth h below the water surface. If P_0 is the atmospheric pressure, rho is the density of water and T is the surface tension of water, what is the pressure inside the bubble?

Water is flowing in a container at a rate proportional to the square of the amount of water present inside the container. If at t =0 volume of water inside the tank is V_(0) & it takes 6 hours for the volume to become 2V_(0) then the time (in hours) taken for the volume to become 4V_(0) is equal to

Read the following paragraph and answer the questions. If heat is exchanged between a hot and cold object, the temperature of the cold object goes on increasing due to gain of energy and the temperature of the hot object goes on decreasing due to loss of energy. The change in temperature continues till the temperatures of both the objects attain the same value. In this process, the cold object gains heat energy and the hot object loses heat energy. If the system of both the objects is isolated from the environment by keeping it inside a heat resistant box (meaning that the energy exchange takes place between the two objects only), then no energy can flow from inside the box or come into the box. i. Heat is transferred from where to where?

How will you state the principle briefly?
