Why does the mass change? The mass of an object does not change with speed; it changes only if we cut off or add a piece to the object. Since mass doesn’t change, when the kinetic energy of an object changes, its speed must be changing. Special Relativity (one of Einstein’s 1905 theories) deals with […]
What are emission spectrums used for?
What are emission spectrums used for? A spectroscope can be used to determine which frequencies have been emitted by a substance. The emission spectrum is a combination of the atomic spectra of the various kinds of atoms making up the substance and can be analyzed to determine the substance’s chemical or atomic composition. What do […]

How do electromagnetic fields affect the human body?
How do electromagnetic fields affect the human body? Low-frequency magnetic fields induce circulating currents within the human body. The strength of these currents depends on the intensity of the outside magnetic field. If sufficiently large, these currents could cause stimulation of nerves and muscles or affect other biological processes. How does frequency affect the human […]

Which amino acid is involved in the formation of disulfide bonds?
Which amino acid is involved in the formation of disulfide bonds? The cysteine amino acid group is the only amino acid capable of forming disulfide bonds, and thus can only do so with other cysteine groups. What two functional groups are found in amino acids? Carboxyl and amino groups are always found in amino acids. […]
