Consider the sun and its largest planet Jupiter. On the line joining them, how far from the center of the sun is their center mass?
 
  Is it within or outside the sun? (Jupiter-sun distance is 778  106 km, diameter of the sun is 1.4  106 km, the sun is 1000 times as massive as Jupiter)

Question 2

An oxygen molecule, O2, falls in a vacuum. From what height must it fall so that its translational kinetic energy at the bottom of its fall equals the average translational kinetic energy of an oxygen molecule at 920 K?
 
  The mass of one O2 molecule is 5.312  10-26 kg, and the Boltzmann constant is 1.38  10-23 J/K. Neglect air resistance and assume that g remains constant at 9.8 m/s2 throughout the fall of the molecule.
  A) 12 km B) 37 km C) 5.2 km D) 24 km E) 49 km

There are over 65,000 known species of protozoa. About 10,000 species are parasitic.

The human body's pharmacokinetics are quite varied. Our hair holds onto drugs longer than our urine, blood, or saliva. For example, alcohol can be detected in the hair for up to 90 days after it was consumed. The same is true for marijuana, cocaine, ecstasy, heroin, methamphetamine, and nicotine.

Did you know?

Symptoms of kidney problems include a loss of appetite, back pain (which may be sudden and intense), chills, abdominal pain, fluid retention, nausea, the urge to urinate, vomiting, and fever.

Did you know?

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa. It is not a straight line, but "zig-zags" around various island chains. Therefore, Samoa and nearby islands have one date, while American Samoa and nearby islands are one day behind. Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.

Did you know?

Cyanide works by making the human body unable to use oxygen.
