How mass of the ball affects the motion of the ball? Both encounter the same air resistance, but, the heavier ball has a greater downward force which overcomes the upward force of the air. The heavier ball will still reach a t erminal velocity. But, it will accelerate longer than the hollow ball, and its […]
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 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 […]
Is Sun Losing its mass?
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 […]
