Earth's temperature the sun emits energy at a rate of about 3.9 · 1026 w. at earth, this sunshine gives an incident energy flux i, of about 1.4kw m”. in this problem, you'll investigate whether any other planets in our solar system could support the sort of water-based life we find on earth. consider a planet orbiting at a distance d from the sun (and let de be earth's distance). the sun's energy flux at distance d is 7 = le(d,/d)2, because energy flux decreases as the inverse square of distance. call the plant's radius r, and suppose that it absorbs a fraction a of the incident sunlight, reflecting the rest back into space. the planet intercepts a disk of sunlight of area 7r? , so it absorbs a total power of tr’al. earth's radius is about 6400 km.

Which of the following bonds would be most polar? a. c-i b. c-br c. c-cl d. c-f e. c-o

In the nineteenth century, gregor mendel first determined some basic rules of genetics that have been observed throughout all types of life. no observations have disproved these basic rules of genetics. charles darwin developed the idea of biological evolution around the same time, but he was unaware of mendel’s discoveries in genetics. over a century later, darwin’s idea of evolution was modified in order to incorporate mendel’s rules of genetics along with the other evidence that darwin had used. what is most likely the relationship between mendel’s rules of genetics and darwin’s idea of biological evolution? a.)mendel’s genetics states laws that are now part of the theory of biological evolution.b.)biological evolution states laws that are part of mendel’s theory of genetics.c.)mendel’s genetics replaced darwin’s entire concept of biological evolution.d.)biological evolution is a law that explains why all genetics exist.

Athird point charge q3 is now positioned halfway between q1 and q2. the net force on q2 now has a magnitude of f2,net = 5.861 n and points away from q1 and q3. what is the value (sign and magnitude) of the charge q3?
