What weather does a cumulus cloud bring? What weather is associated with cumulus clouds? Mostly, cumulus indicates fair weather, often popping up on bright sunny days. Though if conditions allow, cumulus can grow into towering cumulus congestus or cumulonimbus clouds, which can produce showers. What type of weather does a stratus cloud bring? What weather […]
What is the major difference between simmering and poaching?
What is the major difference between simmering and poaching? Poaching is a technique typically used for delicate foods including eggs, fish and fruits. In order to poach food effectively, it must be completely submerged in water. Simmering requires the temperature of the liquid to be between 185 to 200 degrees. What food can be boiled? […]
Which wire has more resistance thick or thin?
Which wire has more resistance thick or thin? The resistance of a thin wire is greater than the resistance of a thick wire because a thin wire has fewer electrons to carry the current. The relationship between resistance and the area of the cross section of a wire is inversely proportional . Which wire produce […]

What are the forces acting on a shopping cart when a woman pushes it? Answer: 1. frictional force, static force, pressure, etc. What acceleration […]
Is mutual inductance always positive?
Is mutual inductance always positive? The mutual inductance LM can be either positive or negative depending on the polarity of the mutual voltage in reference to the direction of the inducing current. Note that the mutual voltage in the second coil can be positive or negative based on the orientation of the coils. Why is […]
What greenhouse gas has over 100x the efficiency of carbon dioxide to reflect light back to the earth?
What greenhouse gas has over 100x the efficiency of carbon dioxide to reflect light back to the earth? A methane molecule has 25 times the global warming potential of a CO2 molecule. A single nitrous oxide molecule has 298 times the global warming potential of a CO2 molecule. Which of the following contribute the most […]
What is a Fourier power spectrum?
What is a Fourier power spectrum? The power spectrum of a time series. describes the distribution of power into frequency components composing that signal. According to Fourier analysis, any physical signal can be decomposed into a number of discrete frequencies, or a spectrum of frequencies over a continuous range. What is voltage spectrum? VSpec calculates […]
How do I know my PNP and NPN sensor?
Is reduction Exergonic or Endergonic?
Is reduction Exergonic or Endergonic? The dehydrogenase enzyme reduces acetaldehyde to ethanol, which is an endergonic (energy-requiring) reaction: The reduction of acetaldehyde is coupled to the oxidation of NADH to NAD+, which is an exergonic reaction. Do oxidation and reduction always occur together? So oxidation and reduction always occur together; it is only mentally that […]
