Michael is driving to Starbucks from his house. He walks 9 miles South to pick up his latte. He then drives 10 miles east to COHEA. What is the displacement of Devin? If it took Michael 2 hours to reach COHEA, then what was his average velocity?

Aparticle moves according to a law of motion s = f(t), 0 ≤ t ≤ 12, where t is measured in seconds and s in feet. f(t) = cos(πt/6) (a) find the velocity at time t (in ft/s).

Frequency of electromagnetic waves that a radio station is assigned is called

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length (in m) of a column of water 1.45 km high for a temperature increase of 1.12°c. assume the column is not free to expand sideways. as a model of the ocean, that is a reasonable approximation, as only parts of the ocean very close to
