What is it called when atoms combine? A molecule is formed when two or more atoms join together chemically. If atoms combine that are of two or more different elements, we call that a compound. All compounds are molecules, but not all molecules are compounds. When two hydrogen atoms combine with one oxygen atom, it […]
What does the speed of sound depend on?
What does the speed of sound depend on? The speed of sound is variable and depends on the properties of the substance through which the wave is travelling. In solids, the speed of transverse (or shear) waves depends on the shear deformation under shear stress (called the shear modulus), and the density of the medium. […]
When two objects vibrate at the same frequency what occurs?
When two objects vibrate at the same frequency what occurs? In conclusion, resonance occurs when two interconnected objects share the same vibrational frequency. When one of the objects is vibrating, it forces the second object into vibrational motion. The result is a large vibration. Which of the following is not a characteristic of a sound […]
Is the following nuclear equation balanced 218 85?
Is the following nuclear equation balanced 218 85? The proton remained in nucleus while electron move away known as beta radiation. So atomic mass will be remained same but atomic no will increase by one. So correct ans will be with 218, 86 Po and beta radiation. Why are equations not written for gamma decays? […]

What is the force of attraction in a solid?
What is the force of attraction in a solid? The gas particles have big distances between them. Solid – In a solid, the attractive forces keep the particles together tightly enough so that the particles do not move past each other. Their vibration is related to their kinetic energy. In the solid the particles vibrate […]

What is a safe way to dispose of radioactive waste?
What is a safe way to dispose of radioactive waste? Disposal of low-level waste is straightforward and can be undertaken safely almost anywhere. Storage of used fuel is normally under water for at least five years and then often in dry storage. Deep geological disposal is widely agreed to be the best solution for final […]
