Which experiment is known as the most beautiful experiment?
Which experiment is known as the most beautiful experiment? The Meselson-Stahl experiment Which model of DNA replication is correct? The semi-conservative model is the intuitively appealing model, because separation of the two strands provides two templates, each of which carries all the information of the original molecule. It also turns out to be the correct […]
When would the center of mass change?
When would the center of mass change? If a system experiences no external force, the center-of-mass of the system will remain at rest, or will move at constant velocity if it is already moving. If there is an external force, the center of mass accelerates according to F = ma. How does the Centre of […]

What is the Contrapositive of p q?
What is the Contrapositive of p q? The contrapositive of a conditional statement of the form “If p then q” is “If ~q then ~p”. Symbolically, the contrapositive of p q is ~q ~p.

What is the significance of Joule-Thomson coefficient?
What is the significance of Joule-Thomson coefficient? An important property of a given gas is its Joule-Thomson coefficient [1-3]. These coefficients are important from two standpoints; (i) intermolecular interaction, and (ii) liquefaction of gases. A given closed system contains one mole of gaseous chemical substance j at temperature T and pressure p. What is the […]
