Re: General Quiz

Hi,

#10345. Name the term in Physics: a property of certain materials (such as iron) that results in a significant, observable magnetic permeability, and in many cases, a significant magnetic coercivity, allowing the material to form a permanent magnet. These materials are noticeably attracted to a magnet, which is a consequence of their substantial magnetic permeability.

#10346. Name the term in Physics: of a material, it is the "lowest liquid temperature at which, under certain standardized conditions, a liquid gives off vapours in a quantity such as to be capable of forming an ignitable vapour/air mixture".

Hi,

#10347. Name the term in Physics: a type of thermodynamic process that occurs without transferring heat between the thermodynamic system and its environment.

#10348. Name the term in Physics: the coldest point on the thermodynamic temperature scale, a state at which the enthalpy and entropy of a cooled ideal gas reach their minimum value. The fundamental particles of nature have minimum vibrational motion, retaining only quantum mechanical, zero-point energy-induced particle motion. The theoretical temperature is determined by extrapolating the ideal gas law; by international agreement, it is taken as 0 kelvin (International System of Units), which is −273.15 degrees on the Celsius scale, and equals −459.67 degrees on the Fahrenheit scale (United States customary units or imperial units).

Re: General Quiz

Hi,

#10351. Name the term in Physics: In physics and chemistry, it is either a proton or a neutron, considered in its role as a component of an atomic nucleus. The number of these in a nucleus defines the atom's mass number (nucleon number).

#10352. Name the term in Physics: the unit of electrical resistance in the International System of Units (SI). It is named after German physicist (1789–1854). Various empirically derived standard units for electrical resistance were developed in connection with early telegraphy practice, and the British Association for the Advancement of Science proposed a unit derived from existing units of mass, length and time, and of a convenient scale for practical work as early as 1861.

Re: General Quiz

Hi,

#10353. Name the term/law in term in Physics: it states that the electric current through a conductor between two points is directly proportional to the voltage across the two points. Introducing the constant of proportionality, the resistance, one arrives at the three mathematical equations used to describe this relationship: V = IR.

#10354. What does the term Cardinal point (optics) mean?
