What is the resistance of an open circuit? An open circuit implies that the two terminals are points are externally disconnected, which is equivalent to a resistance R=∞ . This means that zero current can flow between the two terminals, regardless of any voltage difference. How do you read a 20K ohm meter? The ohm […]
What are some examples of infrared telescopes and where are they located?
What are some examples of infrared telescopes and where are they located? The infrared rays are readily absorbed by the water vapour in Earth’s atmosphere, and most of this water vapour is located at the lower atmospheric regions—i.e., near sea level. Earth-bound infrared telescopes have been successfully located on high mountaintops, as, for example, Mauna […]
What is needed for light propagate?
What is needed for light propagate? A wiggle in space and time is called wave. Sound waves are mechanical waves. In order to propagate sound waves, a medium is necessary; whereas light waves are electromagnetic waves which didn’t require any medium to propagate. Light wave can travel in vacuum also. Does light ever end? Light […]
Where is phytoplankton the most productive?
Where is phytoplankton the most productive? Phytoplankton thrive along coastlines and continental shelves, along the equator in the Pacific and Atlantic Oceans, and in high-latitude areas. Winds play a strong role in the distribution of phytoplankton because they drive currents that cause deep water, loaded with nutrients, to be pulled up to the surface. Where […]
Is cellular respiration a form of combustion?
Is cellular respiration a form of combustion? Although cellular respiration is technically a combustion reaction, it clearly does not resemble one when it occurs in a living cell because of the slow, controlled release of energy from the series of reactions. What are four major differences between combustion and respiration? Difference Between Respiration and Combustion […]
What cycles are caused by the movement of Earth and its moon?
What does magnitude mean?
What does magnitude mean? Magnitude is defined as large in size or very important. An example of magnitude is the depth of the Grand Canyon. An example of magnitude is the size of the problem of world hunger. 36): each increase of one magnitude represents an increase of 2.512 times the brightness. What is the […]
What is the best rpm for fuel economy?
What is the best rpm for fuel economy? Shifting up at 2,000 rpm (1,500 rpm for diesel) gives the best mix of speed and economy. On an automatic with manual shift, short shift to save fuel. The heavier the car, the greater will be its thirst. Does displacement affect gas mileage? Generally speaking, the higher […]

This answer has been confirmed as correct and helpful. What’s the definition of antecedent? An antecedent is a phrase, clause, or word that is later referred back to by an […]
What are some problems in science?
What are some problems in science? 7 Major problems science is facing: A survey overview Financial crunch in academia. Researchers face perpetual struggle to secure and sustain funding. Poor study design in published papers. Lack of replication studies. Problems with peer review. The problem of research accessibility. Lack of adequate and accurate science communication. Stressful […]
