Are lift and drag always perpendicular? The lift and drag forces are the direct result of the relationship between the relative wind and the aircraft. The lift force always acts perpendicular to the relative wind and the drag force always acts parallel and in the same direction as the relative wind. Does induced drag increase […]

What are the similarities and differences between conduction convection? Difference Between Conduction Convection and Radiation Conduction Convection The heat transfer in conduction is slow The heat transfer in convection is faster. The heat transfer occurs through a heated solid object. The heat transfer occurs through intermediate objects. For example, heat transfer between air and water. […]

How do you calculate the force between two wires? Section Summary The force between two parallel currents I1 and I2, separated by a distance r, has a magnitude per unit length given by. Fl=μ0I1I22πr F l = μ 0 I 1 I 2 2 π r . The force is attractive if the currents are […]

Which compound do atoms form bonds by sharing electrons? covalent bond How do you know how many atoms are in a compound? Explanation: Mass → Moles and Moles → Atoms. 196.967 u . So, if you are given the mass of an element, you use the periodic table to find its molar mass, and multiply […]

What is the important of Periscope? The periscope is an instrument for observation over, around or through the object, obstacle or condition that prevents direct line-of-sight observation from the observer’s current position, The periscope is used to monitor the dangerous chemical reactions in the laboratory and they are used in observing the nuclear … What […]

Can you leave a plasma ball on overnight? Can you leave a plasma ball on for long periods of time? For most plasma balls, this isn’t a problem and you should be able to leave them on for as long as you wish. This is typically the case with plasma balls, as they’re not at […]

How can superconductivity be achieved? Artwork: Superconductivity happens when electrons work together in Cooper pairs. But at low temperatures, when the electrons join together in pairs, they can move more freely without being scattered in the same way. What is the best superconductor? Hydrogen sulphide Why is silver not a superconductor? The reason is that […]

What wastes the most water in a home? An average American family uses more than 300 gallons of water daily—70 percent of which occurs indoors. The largest use of household water is to flush the toilet, followed by taking showers and baths. Toilets account for nearly 30 percent of an average home’s indoor water consumption. […]

What are the causes of aerodynamic force? There are two causes of aerodynamic force: the normal force due to the pressure on the surface of the body. the shear force due to the viscosity of the gas, also known as skin friction. What is aerodynamic flow? Aerodynamics, a part of fluid dynamics, describes the laws […]
