Suppose a 91.75 kg hiker has ascended to a height of 1841 m above sea level in the process of climbing Mt. Washington. By what percent has the hiker's weight changed from its value at sea level as a result of climbing to this elevation? Use g=9.807 m/s2 and R=6.371×106 m
. Keep four significant figures in your weight calculation to find the percent difference, and enter your answer as a positive value.

The acceleration due to gravity, g, is constant at sea level on the Earth's surface. However, the acceleration decreases as an object moves away from the Earth's surface due to the increase in distance from the center of the Earth. Derive an expression for the acceleration due to gravity at a distance h above the surface of the Earth, 9h. Express the equation in terms of the radius R of the Earth, g, and h. 9A Suppose a 74.35 kg...
Last year Leah climbed Mt. McKinley (elevation 6200 m above sea level). Her weight at sea level is 70 kg. By how many newtons did her weight change when she went from sea level to the top of Mt McKinley? (The mean radius of the Earth is 6.38 × 106 m.) A) 3.8 N B) 1.3 N C) 4.2 N D) 0.7 N E) 1.6 N
2. What is the height above sea level at which an aircraft must fly in order to procure photography at an average scale of 1:12 000, if the average elevation of the area is 3000 m and the camera to be used has a focal length of 153 mm?
2 What is the height above sea level at which an aircraft must fly in order to procure photography at an average scale of 1:12 000, if the average elevation of the area is 3000 m and the camera to be used has a focal length of 153 mm? The length of a section line (1 mile) lying at an elevation of about 300 m scales 10.16 cm on a photo. The focal length of the carnera used is 153.26...
Consider a height 170 m above the ground (which itself is 1247 m above sea level). If the temperature at this height is 10 C, what is the ratio of the density of this site compared to standard atmospheric conditions (hint - assume you can use the ideal gas law to calculate the density and then divide this value by the standard density value)? (answer to three decimal places)
