What is the principle of magnetic particle inspection?
What is the principle of magnetic particle inspection? The magnetic particle test method of Non-Destructive Examination was developed in the USA, in the 1930s, as a way to check steel components on production lines. The principle of the method is that the specimen is magnetised to produce magnetic lines of force, or flux, in the […]
Where does the energy go when a ball bounces?
Where does the energy go when a ball bounces? When a bouncing ball falls, it initially gains speed or kinetic energy—the energy of motion. When it reaches Earth, it collides head-on with an incredibly massive object that is, from your perspective, at rest. The ball slows down, deforms temporarily and shoots back up. At what […]

These molecules are invisible because when you stretch one, it doesn’t change the electric field. In general, symmetrical molecules with only two atoms are not greenhouse gases. Why is sulfur dioxide not a greenhouse […]
