Sometimes they make food and sometimes they don’t. A spirogyra is plant-like because of the presence of chlorophyll which allows it to make its own […]

How is a frame of reference used to describe motion? Frame of reference refers to something that is not moving with respect to an observer that can be used to detect motion. But if they use objects outside the bus as their frame of reference, they can tell they are moving. How can your frame […]

Is concave or convex better? Concave is better if you press and drag the analog sticks to move them. Convex is better if you push the analog sticks with your thumb to move them. Is a Heptagon convex or concave? Heptagons and other polygons can also be classified as either convex or concave. If all […]

What is the Doppler effect and why does it occur? The Doppler effect is a change in the frequency of sound waves that occurs when the source of the sound waves is moving relative to a stationary listener. As the source of sound waves approaches a listener, the sound waves get closer together, increasing their […]
