How do you protect springs? Protection principles 1. Protect the catchment area above the spring from animals and humans to prevent contamination. 2. Constructing a cut off drain above the spring prevents contaminated water from entering or mixing with the spring water. Why does Florida have so many springs? Florida has an abundance of springs […]
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 is crystallization for Class 7th?
What is crystallization for Class 7th? Crystallization is a process by which a pure soluble substance separates out in the form of crystals from its hot and saturated solution on cooling. The process is employed in the separation of pure common salt from the impure common salt obtained from sea. What is the principle of […]
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? […]
How does bullet kill?
How does bullet kill? Concentrated into a tiny surface area at the bullet tip, it can easily break through your skin. And once it does, that energy and momentum tears through your body, ripping a hole through blood vessels, muscle, and potentially vital organs. No wonder it can kill you. Does a headshot kill instantly? […]
Which jet stream is responsible for burst of monsoon?
Which jet stream is responsible for burst of monsoon? Easterly Jet Stream How jet streams are formed? Jet streams are currents of air high above the Earth. They move eastward at altitudes of about 8 to 15 kilometers (5 to 9 miles). They form where large temperature differences exist in the atmosphere. Cooler, heavier air […]
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 […]
