What are the factors affecting the solubility? Solubility is the maximum amount of a substance that will dissolve in a given amount of solvent at a specific temperature. There are two direct factors that affect solubility: temperature and pressure. Temperature affects the solubility of both solids and gases, but pressure only affects the solubility of […]
Is oxygen a donor or acceptor?
Is oxygen a donor or acceptor? Oxygen is an oxidizing agent (electron acceptor) and hydrogen is a reducing agent (electron donor). What are the best electron donors? When a really good donor meets a great acceptor, the chemical reaction releases a lot of energy. Oxygen (O2) is the best electron acceptor and is used in […]
Why does sand burn your feet?
What is the basic source of magnetism?
What is the basic source of magnetism? The source of magnetism is the electric charges. The movement of the electric charge causes magnetism. Substances are made from tiny atoms. These atoms have protons, electrons and neutrons. Where is magnetism found? A very common source of magnetic field found in nature is a dipole, with a […]
Which of the following factors does not affect the movement of ocean water?
Which of the following factors does not affect the movement of ocean water? Which of the following factors does not affect the movement of ocean water? Temperature. Salinity. How temperature affects the movement of ocean water? Water expands when it warms up – heat energy makes its molecules move around more and take up more […]
What is the relationship between molecular motion and pressure?
What is the relationship between molecular motion and pressure? The greater the molecular motion, the greater the pressure the molecules exert. What is heat in terms of molecular motion? Molecules are in constant motion and so they possess kinetic energy. Molecules at a higher temperature have more kinetic energy i.e. they move faster. Heat is […]
What are examples of an unbalanced force?
What are examples of an unbalanced force? Practically anything that moves is a result of the exertion of unbalanced forces on it. If you kick a football and it moves from one place to another, it means that unbalanced forces are acting upon it. Ball moves from one place to another after kicking it. This […]
What is a matrix material?
What is a matrix material? The matrix is basically a homogeneous and monolithic material in which a fiber system of a composite is embedded. It is completely continuous. The matrix provides a medium for binding and holding reinforcements together into a solid. What is the benefit of composite matrix? Advantages of Composite Materials Low cost […]
What is the lowest order of the Butterworth?
What is the lowest order of the Butterworth? What is the order N of the low pass Butterworth filter in terms of KP and KS? Explanation: We know that, [\frac{Ω_P}{Ω_C}]^{2N} = 10^{-K_P/10}-1 and [\frac{Ω_P}{Ω_C}]^{2N} = 10^{-K_S/10}-1. Which is better FIR or IIR? The advantage of IIR filters over FIR filters is that IIR filters usually […]
What is negative acceleration called?
What is negative acceleration called? The other name of negative acceleration is Retardation or Deceleration. A deceleration is opposite to the acceleration. The deceleration means the decrease in the speed of body/object movement. What is negative acceleration in simple words? According to our principle, when an object is slowing down, the acceleration is in the […]
