How do you know if ions are present? When an atom is attracted to another atom because it has an unequal number of electrons and protons, the atom is called an ION. If the atom has more electrons than protons, it is a negative ion, or ANION. If it has more protons than electrons,it is […]

Can Spider Silk stop a bullet? Spider silk is highly flexible, extremely stretchable, surpasses steel in strength, and most importantly, can be formed into a mesh that would stop a bullet. 22-caliber bullet using just four layers. Can spider webs stop bullets? There is no question the silk would stop a bullet, but due to […]

Why does a paperclip sink in soapy water? When you initially drop the paper clip into the bowl of water, it sinks, as the paperclip is too dense. Adding the dish soap breaks the bonds between the water molecules, thus breaking the surface tension and causing the paper clip to sink. Does a paperclip sink? […]

What happens when blue light passes through yellow filter? The yellow filter absorbs blue. Since the light has only blue and green light in it after passing through the cyan filter, the yellow filter will absorb the blue and let only green light pass through. What are yellow glasses good for? Yellow lenses provide greater […]

What are the function of centrifugation? Centrifugation is a technique used for the separation of particles from a solution according to their size, shape, density, viscosity of the medium and rotor speed. The particles are suspended in a liquid medium and placed in a centrifuge tube. What is the importance of centrifugation? Importance of centrifugation. […]

Does light occupy a single point in space? What it does have though is mass perceived due to the energy it contains and this should not be considered as its actual mass. As light does not have mass, it implies that light cannot occupy space. Why do Photons have no mass? Another answer is that […]

What is a traction boundary condition? Traction free boundary condition means that the the surface is free from external stress. We can mathematically express this as > t = σ.n = 0. where, t is the surface traction in the current configuration; σ = Cauchy stress tensor; n = vector normal to the deformed surface. […]
