Q1. The mass of the carbon atom is 2.0x10^-26.
(A) What is the kinetic energy of a carbon atom moving with the speed of 500 m/s?
(B) Two carbon atoms are joined by spring-like carbon-carbon bond. The potential energy stored in the bond has the value you calculated in part A if the bond is stretched 0.060 nm. What is the bond's spring constant?
Q2. A small boat is moving at a velocity of 3.35 m/s while it is accelerated by a river current perpendicular to the initial direction of motion. If current acceleration is 0.750 m/s^2, what will the new velocity of the boat be after 33.5 s?
In this week's video, Bill Goodykoontz talks about morality and ethics in pop culture. The freedom of speech and expression allows the variety of pop culture media to be released, which may sometimes be offensive material. Can pop culture still have ..
