Which is a better absorber of heat energy land or water?
Which is a better absorber of heat energy land or water? Land surfaces absorb much more solar radiation than water. Water reflects most solar radiation that reaches its surface back to the atmosphere. Since land absorbs more solar radiation the land surface retains more heat as do the vegetation for energy. Thus, land surfaces warm […]

What happens to equilibrium when supply and demand both increase?
What happens to equilibrium when supply and demand both increase? An increase in demand, all other things unchanged, will cause the equilibrium price to rise; quantity supplied will increase. A decrease in demand will cause the equilibrium price to fall; quantity supplied will decrease. A decrease in supply will cause the equilibrium price to rise; […]

Is a phonon a particle?
Is a phonon a particle? Phonon is considered a quasi-particle, beacuse it can exist only in solids as a consequence of vibrational motions: they cannot propagate in vacuum. Does phonon have mass? Acoustic phonons have an energy which is inversely proportional to their wavelength for long wavelength. Therefore, they are massless, like photons. Optical phonons […]

Why are there two Volt Div controls on an oscilloscope?
Why are there two Volt Div controls on an oscilloscope? The vertical section of the scope controls the voltage scale on the display. There are traditionally two knobs in this section, which allow you to individually control the vertical position and volts/div. The more critical volts per division knob allows you to set the vertical […]
