What is the slope of the line with vector equation? Clearly the answer is that the slope is the dot product of the two vectors: slope = g · u. There are two ways to think of the slope of a linear function in a given direction. We can use a symbol, such as s, […]
Why does light bend when it enters a different medium?
Why does light bend when it enters a different medium? The bending of light as it passes from one medium to another is called refraction. The angle and wavelength at which the light enters a substance and the density of that substance determine how much the light is refracted. The bending occurs because light travels […]

Why does borax make bouncy balls?
Why does borax make bouncy balls? The borax acts as a “cross-linker” to the polymer molecules in the glue – basically it creates chains of molecules that stay together when you pick them up. The cornstarch helps to bind the molecules together so that they hold their shape better. How do you make a super […]

What is selective breeding and why is it important?
What is selective breeding and why is it important? Selective breeding, also known as artificial selection, is a process used by humans to develop new organisms with desirable characteristics. Selective breeding can be used to produce tastier fruits and vegetables, crops with greater resistance to pests, and larger animals that can be used for meat. […]
Which has more thermal energy?
Which has more thermal energy? If two objects made of the same substance have different masses or temperatures, you can determine which has more thermal energy. If the objects have different masses but are otherwise the same, the one with more mass has more thermal energy. What is thermal power in short? Thermal power describes […]
