The reason for there being no atmosphere on the Moon is escape velocity of gas molecules. The escape velocity of gas molecules on it is less than their root means square velocity.
The working principle of a washing machine is centrifugation. During the spin cycle, the machine rotates rapidly, creating centrifugal force. This force pushes water and dirt outwards from the clothes, facilitating their separation from the fabric. Centrifugation, accurately describes this ...
Ice floats in water, but sinks in alcohol because ice is lighter than water and heavier than alcohol. This buoyancy phenomenon occurs due to differences in density. Ice has a lower density than water but a higher density than alcohol.
The historical tower of Pisa does not fall even though it is tilted because the vertical line passing through its center of gravity passes through the base. This alignment helps stabilize the tower and prevent it from collapsing despite its ...
