The energy released by larger studio flash units, such as monolights, is indicated in watt-seconds. Canon names its electronic flash units Speedlite , and Nikon uses Speedlight ; these terms are frequently used as generic terms for electronic flash units designed to be mounted on, and triggered by, a camera hot shoe.
The term flashbulb memory was coined by Roger Brown and James Kulik in 1977. [2] They formed the special-mechanism hypothesis, which argues for the existence of a special biological memory mechanism that, when triggered by an event exceeding critical levels of surprise and consequentiality, creates a permanent record of the details and circumstances surrounding the experience.

Exothermic refers to a transformation in which a closed system releases energy (heat) to the surroundings, expressed by Q > 0. {\displaystyle Q>0.} When the transformation occurs at constant pressure and without exchange of electrical energy , heat Q is equal to the enthalpy change, i.e.
Fire is an example of energy transformation Energy transformation using Energy Systems Language. Energy transformation, also known as energy conversion, is the process of changing energy from one form to another. [1] In physics, energy is a quantity that provides the capacity to perform work or moving (e.g. lifting an object) or provides heat.
The oxide keeps the electrons confined to the floating gate. Degradation or wear (and the limited endurance of floating gate Flash memory) occurs due to the extremely high electric field (10 million volts per centimeter) experienced by the oxide. Such high voltage densities can break atomic bonds over time in the relatively thin oxide ...
A pair of Saturday NFL games drew a larger viewing audience than college football for the rollout of the sport's 12-team playoff. The playoff game between SMU and Penn State averaged 6.4 million ...

Energy converter is an example of an energy transformation. For example, a light bulb falls into the categories energy converter. η = P o u t P i n {\displaystyle \eta ={\frac {P_{\mathrm {out} }}{P_{\mathrm {in} }}}} Even though the definition includes the notion of usefulness, efficiency is considered a technical or physical term.
