Why does the volume of a balloon increase during the day but at night decreases? When the ballon is made of elastic material, it expands because of the excess pressure inside. Its volume increases and its internal pressure decreases. As it expands, its buoyancy increases, but not the pull of gravity, so it continues to […]

Does water cool down faster than land? It takes less energy to change the temperature of land compared to water. This means that land heats and cools more quickly than water and this difference affects the climate of different areas on Earth. Different energy transfer processes also contribute to different rates of heating between land […]

What is flat band diagram? 1 Flat band conditions. The flat band diagram is by far the easiest energy band diagram. The term flat band referes to fact that the energy band diagram of the semiconductor is flat, which implies that no charge exists in the semiconductor. An example is shown in the figure below. […]

How do neutrons affect the human body? Consequently, in living tissue, neutrons have a relatively high relative biological effectiveness, and are roughly ten times more effective at causing biological damage compared to gamma or beta radiation of equivalent energy exposure. Neutrons are particularly damaging to soft tissues like the cornea of the eye. How can […]

How do you convert M to Hz? » Wavelength in meters Conversions: m↔Hz 1 Hz = 299792458 m. m↔MHz 1 MHz = 2.99792458E+14 m. What is Hz equivalent to? It is measured in hertz (Hz), an international unit of measure where 1 hertz is equal to 1 cycle per second. Hertz (Hz) = One hertz […]
