How do you calculate the magnitude of the resultant force of two forces acting on an object in the same direction? Two forces that act in opposite directions produce a resultant force that is smaller than either individual force. To find the resultant force subtract the magnitude of the smaller force from the magnitude of […]
How is soap a chemical reaction?
How is soap a chemical reaction? Soaps are sodium or potassium fatty acids salts, produced from the hydrolysis of fats in a chemical reaction called saponification. Each soap molecule has a long hydrocarbon chain, sometimes called its ‘tail’, with a carboxylate ‘head’. What is soap chemically? Soap is a mixture of sodium salts of various […]
How do you calculate the amount of heat needed to raise the temperature?
How do you calculate the amount of heat needed to raise the temperature? To calculate the energy required to raise the temperature of any given substance, here’s what you require: The mass of the material, m. The temperature change that occurs, ΔT. The specific heat capacity of the material, c (which you can look up). […]
What part of the fuel system is responsible for delivering fuel to the engine?
What part of the fuel system is responsible for delivering fuel to the engine? Direct fuel injection systems (also called port fuel injection) have injectors delivering fuel right into the individual combustion chambers and have at least one injector per cylinder. How does an in tank fuel pump work? The basic way your modern electrical […]
At what temperature can gasoline vaporize?
At what temperature can gasoline vaporize? 60 degrees Fahrenheit Does ethanol gas cause vapor lock? The vapor pressure of Ethanol is much lower than the vapor pressure of Gasoline. Therefore a critical vapor liquid ratio, which can cause vapor lock, will be reached at lower temperatures with Gasoline-Ethanol blends than with regular Gasoline. How do […]
What is a control system and why are they important?
What is a control system and why are they important? A control system is a set of mechanical or electronic devices that regulates other devices or systems by way of control loops. Typically, control systems are computerized. Control systems are used to enhance production, efficiency and safety in many areas, including: Agriculture. Chemical plants. How […]
What does the right hand rule explain?
What does the right hand rule explain? The right hand rule states that: to determine the direction of the magnetic force on a positive moving charge, point your right thumb in the direction of the velocity (v), your index finger in the direction of the magnetic field (B), and your middle finger will point in […]

What is the correct formula of absolute pressure?
What is the correct formula of absolute pressure? The total pressure, or absolute pressure, is thus the sum of gauge pressure and atmospheric pressure: Pabs = Pg + Patm where Pabs is absolute pressure, Pg is gauge pressure, and Patm is atmospheric pressure. What is the relation between absolute pressure atmospheric pressure and gauge pressure? […]
What is Ficks first law diffusion?
What is Ficks first law diffusion? Fick’s 1st law of diffusion Diffusion occurs in response to a concentration gradient expressed as the change in concentration due to a change in position, . in which the flux J [cm-2 s-1] is proportional to the diffusivity [cm2/s] and the negative gradient of concentration, [cm-3 cm-1] or [cm-4].
