Where m is the mass of the string and ℓ is the actual length of the string (as opposed to L, the length of the vibrating part of the string). ] The relationship between these quantities is expressed in the following equation: v=μT. Equati...
Liquids do not have definite shape, but they do have definite mass and volume. Liquids are similar to solids because their atoms are close together, but what makes a liquid different is that those atoms can move around. Liquids can change shape by flowing. If you’ve ever spilled a glass...
