Problem 76

Calculate the maximum force in newtons exerted by the blood on an aneurysm, or ballooning, in a major artery, given the maximum blood pressure for this person is 150 mm Hg and the effective area of the aneurysm is 20.0 cm2 . Note that this force is great enough to cause further enlargement and subsequently greater force on the ever-thinner vessel wall.

Notes from Unit 1: Night Sky: Constellations – combinations of stars ­ Originally used by Mesopotamians, adopted and renamed by Greeks ­ 88 catalogued constellations ­ Where they are in the sky changes based on the rotation and orbit of the earth, different constellations are visible at different times of year Circumpolar- stars that are always on the visible horizon (from one of the poles at least) Polaris- star at the north celestial pole Celestial sphere- imaginary sphere around the earth Meridian- circle that passes through the celestial poles Celestial equator- perpendicular the meridian, same as earth’s equator but in the celestial sphere Altitude- how high up something appears in the sky Azimuth- which compass direction something appears in the sky RA (right ascension)- east-west coordinates on the celestial sphere (like longitude) Dec (declamation)- north-south coordinates on the celestial sphere (like latitude) Ecliptic- the path of the sun (through the zodiac equations) Zodiac- 12 constellations in the part of the sky where the sun and planets can be seen, different ones are visible at different times of the year Summer solstice- June 21 , sun is in the highest point of the celestial sphere in the northern hemisphere, longest day here st Winter solstice- December 21 , sun is in the highest point in the southern hemisphere, shortest day in the northern hemisphere Seasons- caused by the earth’s tilt Autumnal Equinox- day and night are of about equal length, days moving from longer to shorter,
