What is the purpose of flight spoilers? The primary purpose of the ground spoilers is to maximise wheel brake efficiency by “spoiling” or dumping the lift generated by the wing and thus forcing the full weight of the aircraft onto the landing gear. The spoiler panels also help slow the aircraft by producing aerodynamic drag. […]
What causes the pail to move in circular motion?
What causes the pail to move in circular motion? As a bucket of water is tied to a string and spun in a circle, the tension force acting upon the bucket provides the centripetal force required for circular motion. As the moon orbits the Earth, the force of gravity acting upon the moon provides the […]
What happens to the current in a circuit if a 1.5 volt battery?
What happens to the current in a circuit if a 1.5 volt battery? What happens to the current in a circuit if a 1.5- volt battery is removed and replaced by a 9-volt battery? The current would increase. 10. The relationship between resistance and current in a circuit is that the greater the resistance the […]
What type of fixed pitch propeller produces more RPM?
What type of fixed pitch propeller produces more RPM? The cruise propeller has a higher pitch, therefore more drag. More drag results in lower RPM and less horsepower capability, which decreases performance during takeoffs and climbs, but increases efficiency during cruising flight. What is the difference between a fixed and variable pitch propeller? For a […]
Is the Earth a positive or negative charge?
Is the Earth a positive or negative charge? Description. Atmospheric electricity is always present, and during fine weather away from thunderstorms, the air above the surface of Earth is positively charged, while the Earth’s surface charge is negative. What is the constant charge of earth? According to the charge-neutrality principle, the electric charge of the […]
What are 3 ways an object can be charged?
What are 3 ways an object can be charged? In order to charge an object, one has to alter the charge balance of positive and negative charges. There are three ways to do it: friction, conduction and induction. What is a charged object give three examples? There are three ways that objects can be given […]
Why is oxygen not suitable for a light bulb?
Why is oxygen not suitable for a light bulb? A light bulb full of oxygen would not work well, as the bulb’s tungsten filament, if it ignited at all, would burn very brightly and short out quickly. Oxygen is flammable, a decided fire hazard that would ignite the bulb’s insides. Why are light bulbs filled […]
What is the best solvent for recrystallization?
What is the best solvent for recrystallization? For a solvent pair, the first solvent should readily dissolve the solid. The second solvent must have a lower solubility for the solute and be miscible with the first solvent. Common solvent pairs include ethyl acetate and hexane, toluene and hexane, methanol and dichloromethane, and water and ethanol. […]
