When light with a frequency fi = 547.5 thz illuminates a metal surface, the most energetic photoelectrons have 1.260 x 10-19 j of kinetic energy. when light with a frequency fo = 738.8 thz is used instead, the most energetic photo-electrons have 2.480 x 10-19 j of kinetic energy. using these experimental results, determine (a) the approximate value of planck's constant. h = jos (b) the work function for this metal. ~ (hint for part (b): use the two-point formula that you learned in algebra: y-yı = *=*(x - 1)

It is reasonable to assume that the bulk modulus of blood is about the same as that of water (2.2 gpa). as one goes deeper and deeper in the ocean, the pressure increases by 10000 pa for every meter below the surface. if a diver goes down 80.0 m in the ocean, by how much does each cubic centimeter of her blood change in volume? give the answer in cubic centimeters (actually one cubic centimeter equals one milliliter).

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.
