1. The planet Mars requires 2.47 years to orbit the sun, which has a mass of 1.989 × 10^30 kg, in an almost circular trajectory. Find the radius of the orbit of Mars as it circles the sun. The gravitational constant is 6.672 × 10−11 N · m2 /kg2 . Answer in units of m. 2. Find the orbital speed of Mars as it circles the
sun. Answer in units of m/s.

The law of entropy can also be called the law of increasing disorder, but this law seems to contradict the existence of living organisms that are able to organize chemicals into organic molecules. prepare for a class debate on the validity of the following arguments: a. living things are not subject to the laws of thermodynamics. b. the increase in the universe's entropy due to life processes is greater than the decrease in entropy within a living organism.
