Are eigenvectors Orthonormal?
Are eigenvectors Orthonormal? 1) Eigenvectors can always be scaled. So if v is an eigenvector then so is av for a∈k∗. So if each eigenvalue has multiplicity one a basis of eigenvectors is automatically orthogonal (and can be made orthonormal as above). In general we need to find an orthogonal basis of each eigenspace first, […]
Is DownTek real down?
Is DownTek real down? What is DownTek™ Water Repellent Down? DownTek™ is down that has been treated with a DWR (Durable Water Repellency) and renders the down hydrophobic. DownTek™ is currently available in either it’s original C6 formula, or the PFC-Free™ formula. Why is down a good insulator? Down feathers are great thermal insulators. The […]
What do switches do in a circuit?
What do switches do in a circuit? A Switch. An electrical switch serves the purpose of controlling the flow of electrical current within a circuit. It can be used to both inhibit the flow of the current or to initiate it. What happens when you remove a bulb from a parallel circuit? Nothing happens to […]

Which animal phyla is most advanced? Cards Term What is an animal? How is an animal different from an autotroph? Definition Animals are active multicellular organisms […]
Which one of the following can be polarized?
Which one of the following can be polarized? Example electromagnetic waves. Hence, X rays can be polarised. Sound waves in air travel parallel to the direction that the particles within it oscillate it therefore they are longitudinal in nature – it propagates in 1 dimensional direction so it can not be polarized. Can heat waves […]
Which type of energy transfer does not require matter?
Which type of energy transfer does not require matter? The transfer of thermal energy by conduction and convection does not require matter. 2. The transfer of thermal energy by radiation does not require matter. What would result in being able to dissolve a greater amount of gas in a solution? An increase in temperature decreases […]
Is the hot tap always on the left?
What is the formula of law of inertia?
What is the formula of law of inertia? Inertia of an object is the resistance offered by the object to change in its motion or position. Simply, it is the resistance that the object will apply to an external opposite force. Translational Inertia = ma, where “m” is the mass, and “a” is the acceleration […]
