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 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 […]
Does the Earth revolve around the sun once a year?
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 will make an object move in a circular path?
What will make an object move in a circular path? A centripetal force is a net force that acts on an object to keep it moving along a circular path. The tension force in the string of a swinging tethered ball and the gravitational force keeping a satellite in orbit are both examples of centripetal […]
Can a translation undo a reflection?
Can a translation undo a reflection? No. The translation followed by a reflection would put a figure in a different location in the plane when compared to the same reflection followed by the same translation. Summarize, or have students summarize, the lesson. We can sequence rigid motions. What does translation do to an image? Translation […]
What are the major causes of freshwater pollution?
What are the major causes of freshwater pollution? Pollution may be caused by fecal waste, chemicals, pesticides, petroleum, sediment, or even heated discharges. Polluted rivers and lakes are unfit for swimming or fishing; polluted water is unsafe to drink. How does water use impact the environment? Less Water Affects the Environment When reservoir water levels […]
What Colour would green be in red light?
What Colour would green be in red light? There are three primary colours in light: red, green and blue….Coloured light. Appearance of object in red light White paper Red (only red light to reflect) Red apple Red Green apple Black (no green light to reflect) Why do red and green light make yellow? A mixture […]
Is it more energy efficient to boil water?
Is it more energy efficient to boil water? An electric stove requires more energy and time to heat up, thus it takes longer to heat the water inside the kettle. However, an electric stove is more efficient in delivering energy to the kettle. Using boiling water and vinegar removes mineral deposits that reduce its energy […]
Which WiFi frequency is best?
Which WiFi frequency is best? Ideally, you should use the 2.4GHz band to connect devices for low bandwidth activities like browsing the Internet. On the other hand, 5GHz is the best suited for high-bandwidth devices or activities like gaming and streaming HDTV. What is the advantage of having WiFi in your car? Benefits of car […]
