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 […]

How does air resistance affect cars?
How does air resistance affect cars? Air friction does not significantly affect a car’s gas mileage. Cars are slowed down when they stir up the air too much. Stirring up the air creates vortices and billows that take energy away from the car. This effect is known as “wake drag”, “pressure drag”, or “form drag”. […]
What are the common group of minerals?
What are the common group of minerals? Silicates, oxides, sulfates, sulfides, carbonates, native elements, and halides are all major mineral groups. Silicates. Oxides. Sulfates. Sulfides. Carbonates. Native Elements. Halides. What are the two main groups of minerals? All minerals, however, can be classified into two main groups—silicate minerals and nonsilicate minerals—based on the chemical compositions […]
How do you solve relative error?
How do you solve relative error? To calculate relative error, subtract the measured value by the real value and then divide the absolute of that number by the real value to get the relative error. We can then multiply by 100% to get the percent error. What is actual error? The actual error, as said […]
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 […]
Which represents the size of a population?
Which represents the size of a population? Population size is the number of individuals in a population. For example, a population ofinsects might consist of 100 individual insects, or many more. Population size influences the chances of a species surviving or going extinct. Generally, very small populations are at greatest risk of extinction. What are […]
What causes a changing magnetic field?
What causes a changing magnetic field? The changing magnetic field caused by the material’s motion induces a current in the coil of wire proportional to the change in field. For a 1, the magnetic field changes from one direction to the other; this change induces a current in the coil. What happens when electric and […]
