Which state is headed by a monarch, elected every five years? Malaysia is a constitutional monarchy, but the title of monarch there is not for life, but is elected. The fact is that Malaysia is divided into states, 9 of which are also monarchies (they are ruled by 7 sultans, one raja and another ruler with the title of Yang Dipertuan Besar). Every five years, these monarchs choose a chief monarch from among themselves, usually by seniority or by length of reign. Although, in the end, they all perform only representative functions. Authors: Jimmy Wales, Larry Sanger Random interesting fact from the Great Encyclopedia: How does an airplane take off? To understand how an airplane rises into the air, we first need to understand the forces that keep airplanes in the air. Since an airplane weighs more than the same volume of air, it needs a force to keep it in the air. It's called lifting power. The aircraft develops this force by rapidly moving forward and overcoming air resistance. Why does this movement create lift? Due to the fact that in the process of its air masses flow around the wings. The air dissected by an airplane passes over and under the wings. That part of it that passes under the wings pushes the plane up. The wing has a convex shape on the upper side, and the air, bending around this bulge, creates a zone of low pressure at these points. Thus, there are two forces acting simultaneously: the air under the wings pushes the aircraft up, and the reduced pressure above the wings contributes to this movement. The result is an uplift. To move forward, the aircraft needs the power of the engine. Propellers are screwed into the air just like a screw into wood. This effect becomes possible due to the fact that the air, when moving quickly through it, as well as when the air itself moves quickly, begins to act as a dense medium. This forward movement is called thrust. Thrust overcomes air resistance, lift overcomes the force of gravity - and the plane flies through the air. As long as the lift force balances the gravitational forces, the plane moves straight ahead at the same level. As the speed increases, the aircraft will shoot up as the lift force has increased and the pilot needs to lower the nose of the aircraft slightly to counteract this force. If the speed decreases, the pilot must raise the nose of the aircraft slightly up. If this is not done, the air flow around the wings is stalled, the aircraft loses lift and, accordingly, speed, risking entering a tailspin. If the stall occurs high in the sky, this height is enough to level the plane and pick up speed again, but if it happens low above the ground, disaster is inevitable.
