A liquid in a container exerts equal pressure in all directions on the bottom of the container, on its walls and even upwards.
Gases exert pressure equally in all directions, Why ?
The force of buoyancy exerted by the atmosphere on a balloon is B in the upward direction and remains constant. The force of air resistance on the balloon acts opposite to the direction of velocity and is proportional to it. The balloon carries a mass M and is found to fall down near the earth's surface with a constant velocity v. How uch mass hsould be removed from teh balloon so that it may rise with a constant velocity v?
An ideal gas mixture filled inside a balloon expands according to relation PV^(1/2) constant. The temperature of the gas inside the balloon is:
An ideal gas mixture filled inside a balloon expands according to the relation expands according to the relation PV^(2//3)= constant. What will be the temperature inside the balloon
The ratio of excess pressure inside a soap bubble to the excess of pressure inside an air bubble in a soap solution is
The hot air balloon rises because it is
A rubber balloon is given a charge. Q distributed uniformly over its surface. Is the field inside the balloon zero everywhere if the balloon does not have a spherical surface?
Liquids and gases exert pressure in all directions. They exert pressure on the walls of the container also.
