The Mars roving-laboratory parachute, a 55-ft-diameter disk-gap-band chute with a measured drag coefficient of 1.12. Mars has very low density, about 2.9E-5 slug/ft3, and its gravity is only 38% of earth gravity. If the mass of payload and chute is 1500 kg, estimate the terminal fall velocity of the parachute. Round the final answer to three decimal places.

Explain the comparisons between nature and packingtown that appears on pages 81 and 82 answer

Isobars are lines of constant or equal pressure on a weather map. they can be used to find areas of low or high pressure over a broad area, and they can tell us how intense the system may be. on weather maps, you may have noticed areas that have a large l or h over a region with lines circling around them. the l stands for low pressure and h stands for high pressure. the lines circling them are isobars. check out the pressure system and isobars over georgia and florida. what is the present weather in this area ? a) clear and sunny b) cold and cloudy c) changing weather d) lots of precipitation

An astronaut on the moon throws a baseball upward. the astronaut is 6 ft, 6 in. tall, and the initial velocity of the ball is 3030 ft per sec. the height s of the ball in feet is given by the equation s equals negative 2.7 t squared plus 30 t plus 6.5s=−2.7t2+30t+6.5, where t is the number of seconds after the ball was thrown. complete parts a and b.
