What type of system is a hydraulic system? A hydraulic system is a drive technology where a fluid is used to move the energy from e.g. an electric motor to an actuator, such as a hydraulic cylinder. The fluid is theoretically uncompressible and the fluid path can be flexible in the same way as an […]

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 […]

What does emission mean? An emission is something that has been emitted—released or discharged. In general, emissions consist of things like gas, liquid, heat, sound, light, and radiation. This exhaust is just one form of carbon emissions—greenhouse gases from various sources that are known to contribute to global warming and climate change. What is emissions […]

What is the primary use of the following agar slant agar deep broth? What is the primary use of slants? Provides a solid growth area that is easier to store. What is the primary use of deeps? Used to grow bacteria that needs less oxygen. What are agar deep used for? Agar deeps are used […]

What is the primary rule of soccer? The two basic soccer rules for a proper throw-in are to have both feet on the ground and to throw the ball with both hands over the head. For teaching purposes it is common to allow players under the age of 8 to take more than 1 attempt. […]

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 […]

Does a box plot show the mean? A boxplot, also called a box and whisker plot, is a way to show the spread and centers of a data set. Measures of spread include the interquartile range and the mean of the data set. Measures of center include the mean or average and median (the middle […]

Does the Earth revolve around the sun once a year? The Earth moves in two different ways. Earth orbits the sun once a year and rotates on its axis once a day. The Earth’s orbit makes a circle around the sun. Can we offer water to sun during solar eclipse? Or you can also offer […]

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 […]
