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 […]
What organs are part of the cardiorespiratory system?
What organs are part of the cardiorespiratory system? The cardiorespiratory system consists of the heart and blood vessels, which work with the respiratory system (the lungs and airways). These body systems carry oxygen to the muscles and organs of the body, and remove waste products, including carbon dioxide. Is 30 minutes of cardio 3 times […]
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 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 […]
How does light act like a particle?
How does light act like a particle? Light behaves mainly like a wave but it can also be considered to consist of tiny packages of energy called photons. Photons carry a fixed amount of energy but have no mass. They also found that increasing the intensity of light increased the number of electrons ejected, but […]
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 […]
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 […]
