What results when a wave reflects off a fixed boundary? The right end is held tightly; it is a fixed end. The wave reflects off this fixed end and returns as a downward displaced pulse. Reflection off a fixed end results in inversion. What happens to a wave at a fixed boundary? A wave reflected […]

Which is the SI unit? There are seven basic units in the SI system: the meter (m), the kilogram (kg), the second (s), the kelvin (K), the ampere (A), the mole (mol), and the candela (cd). What is dimension formula? Dimensional formula (equation) (Definition) : An equation, which gives the relation between fundamental units and […]

What is the relationship between rolling static and sliding friction? Static, sliding, and rolling friction occur between solid surfaces. Static friction is strongest, followed by sliding friction, and then rolling friction, which is weakest. Fluid friction occurs in fluids, which are liquids or gases. What is the cause of friction What is the difference between […]

What happens when a solid turns into a liquid? When a solid is heated the particles gain energy and start to vibrate faster and faster. Although the particles are still loosely connected they are able to move around. At this point the solid is melting to form a liquid. The particles in the liquid are […]

What is the relationship between the kidneys and the liver? Generally speaking, the liver and kidney are key organs for regulation of homeostasis and metabolism in the body: the liver is the major player for metabolism of glucose (energy), protein, and lipid, and kidney is that for homeostasis of water, electrolytes, and acid-base balance. What […]
