Why are electric fans important? Fans are used for circulating air in rooms and buildings; for cooling motors and transmissions; for cooling and drying people, materials, or products; for exhausting dust and noxious fumes; for conveying light materials; for forced draft in steam boilers; and in heating, ventilating, and air-conditioning systems. Are electric fans better […]
Does decay constant change?
Does decay constant change? Yes, the decay half-life of a radioactive material can be changed. Radioactive decay happens when an unstable atomic nucleus spontaneously changes to a lower-energy state and spits out a bit of radiation. This process changes the atom to a different element or a different isotope. Why is rate of decay constant? […]
In what direction and at what point does buoyant force on a body due to a liquid act?
In what direction and at what point does buoyant force on a body due to a liquid act? The buoyant force on an object immersed in a liquid acts in the vertically upward direction. Buoyant force acts in the direction opposite to the direction in which weight of the object acts. The buoyant force is […]

Does velocity depend on speed?
Does velocity depend on speed? So speed depends on distance traveled, while velocity depends on the displacement. It’s because the velocity changes when the direction changes that the velocity can average to zero even though it isn’t zero at any particular time. What is the velocity of wave? Wave velocity in common usage refers to […]

What is the employee productivity ratio?
What is the employee productivity ratio? The labor productivity ratio is a metric expressing the number of work units produced per time worked. Productivity ratios essentially quantify output/input, with input being time worked and output being work units. If the worker produces 1000 widgets in a week, the productivity ratio might be 1000/40. How do […]
