What happens when an ultrasound wave reaches a boundary? When ultrasound waves reach a boundary between two substances with different densities, they are partly reflected back. The remainder of the ultrasound waves continue to pass through. A detector placed near the source of the ultrasound waves is able to detect the reflected waves. How does […]

What does it mean when an object has potential energy?
What does it mean when an object has potential energy? To summarize, potential energy is the energy that is stored in an object due to its position relative to some zero position. An object possesses gravitational potential energy if it is positioned at a height above (or below) the zero height. What are the two […]

How do you calculate water displacement on a boat?
How do you calculate water displacement on a boat? The volume below the float plane times the weight of water (fresh is 62.4 and salt is 64.) equals the displacement of the boat. The displacement of the boat minus the boat weight divided by five is the maximum safe load. First divide you boat up […]
Does cubical Expansivity depends on original volume?
Does cubical Expansivity depends on original volume? Does cubical expansivity depend upon initial volume of solid? Yes. Because we know cubical expansivity is equal to rise in increase in volume per unit initial volume per unit rise in temperature, where ratio of increase in volume and initial volume is constant. When a circular disc having […]
What is recrystallization process?
What is recrystallization process? Recrystallization is a purification technique for solid compounds. To perform recrystallization, an impure solid compound is mixed with hot solvent to form a saturated solution. As this solution cools, the solubility of the compound decreases, and pure crystals grow from solution. What is crystallization answer? Crystallization is a process whereby solid […]

Are we lighter at night?
Are we lighter at night? Simple question: Are we lighter in night because of the moon’s gravity? No, you’re lighter when the Moon is overhead, which has nothing to do with day or night. This is of course an incredibly miniscule change which won’t have any noticeable effect on you. Is there less gravity at […]
