Which types of energy are most commonly dissipated?
Which types of energy are most commonly dissipated? Energy is usually lost by heating up the surroundings though sometimes energy is dissipated as sound waves. for a radio or set of speakers, the electrical work is transferred into useful sound waves and infrared radiation is dissipated – ie wasted as heat energy. What is Joule […]

Does tension increase as length increases?
Does tension increase as length increases? Researchers have found that both of these structures can contribute to passive tension during muscle fiber elongation. As the muscle fiber (and therefore each sarcomere within it) is tested at longer lengths, the available sites for myosin to bind to actin are increased, and the amount of force increases. […]
Are CRTs dangerous?
Are CRTs dangerous? Color CRTs may contain mercury or other potentially toxic materials. If the CRT is broken or cracked, these materials may be released and pose a risk of toxic exposure.

What is the electric potential if the electric field is zero?
What is the electric potential if the electric field is zero? If the electric field is zero, then the potential has no gradient i.e.: the potential is equal across space. But potential is always measured relative to a baseline, so it can therefore be considered as zero. Can electric potential at a point be zero […]
