What is Hooke law
Hooke's law (R. Hooke): The stress exerted to any solid is proportional to the strain it generates within the elastic limit for that solid. The constant of that proportionality is the Young modulus of elasticity for that material.
Twin paradox: One of the most well-known "paradoxes" in history, predicted by Sir Einstein's special theory of relativity. It takes two twins, born on similar date on Earth. One, Albert, leaves home for a trip about the Universe at very high speeds (v
Cosmological redshift: The effect where light emanates from a distant source appears redshifted since of the expansion of the space time itself.
Explain in brief that the gas encompass density or not?
Watt: W (after J. Watt, 1736-1819): The derived SI unit of power, stated as a power of 1 J acting over the period of 1 s; it therefore has the units of J/s.
Describe when the intermolecular forces are strongest? Briefly state it.
Charles' law (J.A.C. Charles; c. 1787): The volume of an ideal gas at constant (steady) pressure is proportional to the thermodynamic temperature of that gas.
Briefly describe the reason why it takes longer to heat a bucket of water than the cup of water?
State is it possible that the nucleus consists of negative mass defect?
What do you mean by the term cardiac output? Briefly explain it.
Kilogram: kg: The basic SI unit of mass that is the only SI unit still maintained by a physical artifact: a platinum-iridium bar reserved in the International Bureau of Weights and Measures at Sevres, France.
