Weightlessness occurs in the zero state of gravity. In this condition, objects experience apparent weightlessness because there is no gravitational force acting on them. Weightlessness can be simulated in environments such as space, where objects and individuals float freely due ...
Steel is the most elastic among the options provided. Elasticity refers to a material’s ability to regain its original shape after deformation. Steel exhibits high elasticity, making it ideal for structural applications where resilience and durability are crucial.
A storm is predicted when the pressure of the atmosphere suddenly decreases. A rapid drop in atmospheric pressure often indicates the approach of a storm system. This decrease in pressure is associated with unstable weather conditions, including strong winds, precipitation, ...
The egg floats in concentrated salt solution because the density of the salt solution is greater than the density of the egg. The increased density of the salt solution provides greater buoyant force, causing the egg to float. In soft ...
The reason for water droplets not sticking to oily surfaces is primarily due to the lack of adhesive force. Water and oil have different polarities, resulting in weak adhesive forces between them, preventing water droplets from adhering to oily surfaces ...
The continent known as an “island continent” is Australia. This nickname arises from the fact that Australia is both a continent and a single, massive landmass surrounded entirely by water, making it the world’s largest island and smallest continent.
H5N1 bird flu virus is a highly contagious avian influenza virus that primarily affects birds but can infect humans. It poses a significant public health concern due to its potential to cause severe illness and fatalities in both birds and ...
