Square hvat is used as the basis for other units of surface in the hvat system. motika; one motika = 200 square hvats = 719.3304 square meters.; jutro ("morning", compare the unit Morgen) or Joch in Austria; one jutro = 8 motika = 1,600 square hvats [1] = 5,754.6432 square meters.
For gases, departure from 3 R per mole of atoms is generally due to two factors: (1) failure of the higher quantum-energy-spaced vibration modes in gas molecules to be excited at room temperature, and (2) loss of potential energy degree of freedom for small gas molecules, simply because most of their atoms are not bonded maximally in space to ...

For example, 1 kilometre is 10 3 (one thousand) times the length of 1 metre, but 1 square kilometre is (10 3) 2 (10 6, one million) times the area of 1 square metre, and 1 cubic kilometre is (10 3) 3 (10 9, one billion) cubic metres.
Investigators are trying to determine how a woman got past multiple security checkpoints this week at New York’s JFK International Airport and boarded a plane to Paris, apparently hiding in the ...
K, with a half-life of 1.25 × 10 9 years, decays to stable 40 Ar (11.2%) by electron capture or positron emission, and also to stable 40 Ca (88.8%) by beta decay. These properties and ratios are used to determine the age of rocks by K–Ar dating. [25] [26] In Earth's atmosphere, 39 Ar is made by cosmic ray activity, primarily by neutron ...

M 2 is useful because it reflects how well a collimated laser beam can be focused to a small spot, or how well a divergent laser source can be collimated. It is a better guide to beam quality than Gaussian appearance because there are many cases in which a beam can look Gaussian, yet have an M 2 value far from unity. [1]
