An airplane pilot flies due west at a speed of 216 km/hr with respect to the air. after flying for a half an hour, the pilot finds themselves over a town that is 119 km west and 27 km south of their starting point. a- determine the magnitude of the velocity of the wind with respect to the ground.
(include units with the answer)
b-determine the direction of the velocity of the wind with respect to the ground measured as west from the south.
(include units with the answer)

the answer is b ) square root of 5

the five characteristics of adolescence are biological growth and development, and undefined status, increased decision making, increased pressure and the search of self.

bacteria that live on the ocean floor are sustained by phytoplankton. phytoplankton, microscopic marine photosynthetic organisms, have a vastly significant role to play not only in the marine food web of which they’re part of, but also on a more global scale. despite their infinitely small size in comparison to other marine organisms, these tiny creatures occupy an immensely important ecological niche: they are the foundation of the marine food web, and as primary producers, play key roles in supporting all other organisms in the marine environment, as well as in the regulation of the earth’s climate through the sequestration of carbon, oxygen production, and other related processes. phytoplankton account for roughly half of all global primary productivity; therefore, their significance extends far beyond the marine environment alone. there is an intriguing sense of irony in the realization that these tiny living beings that often live out their existence unnoticed and undetected by the rest of the world, have such a far-reaching impact on the lives of virtually all other living organisms on the planet, particularly on those in the marine environment. the world that we have become accustomed to has been and is continuously shaped by the workings of these miniscule yet vital “plants of the sea”.

hope this !
