When Paris was shelled from 100 km away with the WWI
Chapter , Problem 3(choose chapter or problem)
When Paris was shelled from 100 km away with the WWI long-range artillery piece "Big Bertha," the shells were fired at an angle greater than \(45^{\circ}\) to give them a greater range, possibly even twice as long as at \(45^{\circ}\). Does that result mean that the air density at high altitudes increases with altitude or decreases?
