In 1993 the radius of hurricane emily was about 350 km/h. the wind speed near the center ("eye") of the hurricane, whose radius was about 30 km, reached about 200 km/h. as air swirled in from the rim of the hurricane toward the eye, its angular momentum remained roughly constant. a) estimate the wind speed at the rim of the hurricane. b) estimate the pressure difference at the earth's surface between the eye and the rim (hint: the density of air (1 atm, 20 c) is 1.20 kg/m^3 .) c) where is the pressure greater? d) if the kinetic energy of the swirling air in the eye could be converted completely to gravitational potential energy, how high would the air go?

what was the answer?

the word that best describes martin luther king jr.'s tone in the video is dignified

martin luther king, jr. was a social activist and baptist minister who played a key role in the american civil rights movement from the mid-1950s until his assassination in 1968. the video shows his manner and attitude having or showing a composed or serious manner that is worthy of respect so dignified is the correct answer

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
