What happens to atmospheric pressure with increase in altitude? (1) It remains constant (2) It decreases (3) It increases (4) It constantly fluctuates

Description : What happens to atmospheric pressure with increase in altitude? (1) It remains constant (2) It decreases (3) It increases (4) It constantly fluctuates

Last Answer : (2) It decreases Explanation: In most circumstances atmospheric pressure is closely approximated by the hydrostatic pressure caused by the mass of air above the measurement point. Low- ... increases, there is less overlying atmospheric mass, so that pressure decreases with increasing elevation.

My new macbook air has a maximum operating altitude of 3000 meters / 10000 feet. Does this mean that people in La Paz, Bolivia cannot use macbook air computers?

Description : My new macbook air has a maximum operating altitude of 3000 meters / 10000 feet. Does this mean that people in La Paz, Bolivia cannot use macbook air computers?

Last Answer : answer:The problem with altitude, as far as the Macbook Air is concerned, is one of cooling. As air density decreases with altitude, the air becomes less effective at drawing heat away from the heat sink, and ... disc, and it can crash. Solid-state drives, like in your Air, don't have this problem.

One sunny afternoon, three men go for a ride on a hot air balloon over the Sahara desert. An hour into the trip, the balloon begins to lose altitude.
