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”. […]
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 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 […]
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… […]

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 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 […]
