What is the SI unit of viscosity?
What is the SI unit of viscosity? The SI unit for kinematic viscosity is square meters per second (m2/s). However, due to the viscosity values of most common fluids, square centimeters per second (cm2/s) is used more often. Note that 1 cm2/s is equivalent to 100 cSt. What is retardation write its formula? Deceleration also […]
What is the relationship between energy and frequency?
What is the relationship between energy and frequency? Just as wavelength and frequency are related to light, they are also related to energy. The shorter the wavelengths and higher the frequency corresponds with greater energy. So the longer the wavelengths and lower the frequency results in lower energy. The energy equation is E = hν. […]
