What are the 6 common properties of electromagnetic radiation? Properties of Electromagnetic Radiation These magnetic and electric waves travel perpendicular to each other and have some characteristics like wavelength, amplitude, and frequency. Some basic properties of Electromagnetic Radiation are given in the points mentioned below. They can travel through empty space. What are the four […]
Is it rude to say here you go?
What four methods are used most often in persuasive speeches on questions of policy?
What four methods are used most often in persuasive speeches on questions of policy? – The four methods of organization used most often in persuasive speeches on questions of policy are: problem-solution order, problem-cause-solution order, comparative advantages order, and Monroe’s motivated sequence. What are the three basic issues of persuasive speeches on questions of policy? […]
What is Loop rule?
What is Loop rule? Kirchhoff’s loop rule states that the sum of all the electric potential differences around a loop is zero. It is also sometimes called Kirchhoff’s voltage law or Kirchhoff’s second law. The rule is an application of the conservation of energy in terms of electric potential difference, Δ V \Delta V ΔV […]
Can a chemical change be reversed?
Can a chemical change be reversed? A chemical change occurs whenever matter changes into an entirely different substance with different chemical properties. Because chemical changes result in different substances, they often cannot be undone. What is a chemical change that Cannot be reversed? Burning is a non-reversible chemical change. When you burn wood, the carbon […]
How can we reduce harmonics in power system?
How can we reduce harmonics in power system? To attentuate harmonics, users can use passive filters, inductive reactors, phase-shifting transformers, active filters, or multi-pulse converter sections. Passive filters apply tuned series L-C circuits (circuits with inductance and capacitance) that attentuate specific harmonic frequencies. How much current total harmonic distortion is acceptable? increased temperatures and interference […]
What causes light beams to be parallel?
What causes light beams to be parallel? A narrower beam of laser light spreads out more quickly than a wider beam. Only an infinitely wide beam (a plane wave) does not spread out, and therefore has parallel waves. Divergence is observed by shining a laser light on a wall and then seeing the spot grow […]
Do humans have gill slits?
Do humans have gill slits? …and other nonaquatic vertebrates exhibit gill slits even though they never breathe through gills. These slits are found in the embryos of all vertebrates because they share as common ancestors the fish in which these structures first evolved. Human embryos also exhibit by the fourth week of development a well-defined… […]
How do you find a circular displacement?
How do you find a circular displacement? Angular displacement of a point can be given by using the following formula, Angular displacement = \theta _{f}- \theta _{i} Where, dv = a dt. Integrating on both sides, v – u = at. Also, v^{2} – u^{2} =2as. Substituting the value of u from the equation 1 […]
Can two waves with different frequencies interfere?
Can two waves with different frequencies interfere? 2 Answers. No; wave interference takes place whenever two waves of any frequency, same, nearly the same or widely different interact. An air molecule next to your ear, for example, can only respond to the sum of all the different sound waves reaching it at any moment. What […]
