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 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 […]

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 […]

What is the formula for energy transformation? An object that has potential energy has energy by virtue of position and is related by the Newtonian equation PE=mgh (where m equals mass in Kg, g the acceleration due to gravity—approximately 9.8 m/s2 near Earth’s surface—and h equals height in meters). Is a potato a bulb? Potatoes […]
