The minimum wind speed required to produce wind energy is typically around 7-10 miles per hour. This is the speed at which most wind turbines start generating electricity efficiently.
true
activation energy
depths of Field means The range of distance along the axis of an optical instrument which the object will produce a relatively distinct image
The minimum speed of 6v motor to produce electricity is 15 Mph.
One mole of CO2 requires one mole of O2 to produce during combustion of carbon-containing compounds.
Depends on the quality of the sound. The minimum distance to hear an echo will be partly based upon the observers ability to resolve different sounds (i.e. so that they can distinguish between the actual noise, and the arrival of the reflected sound - a little 100 year old lady may not be as good as a 15year old!). This will vary between observers, as their auditory reaction times vary In the perfect Physics world though: Assuming a sharp sound (like a gunshot) the minimum distance (d=vt) to hear distinct echo is 17.2m considering the speed of sound to be 344ms. In general the "minimum echo distance" is always equal to half a wavelength from the reflector.
Coherent sources are required to produce interference of light because they have a constant phase difference between them. This phase relationship allows the light waves to either reinforce or cancel each other out, creating distinct interference patterns. Incoherent sources have random phase relationships, leading to a lack of interference effects.
The minimum amount of unstable atoms needed to produce an uncontrolled chain reaction is called?
Yes, bacteria can produce distinct smells, which can vary depending on the type of bacteria and the environment in which they are present.
Yes, bugs can have a distinct smell due to the chemicals they produce for communication, defense, or attracting mates.
