How fast is the Milky Way moving thru space? 1.3 million miles per hour How fast is the Milky Way galaxy moving? 130 miles per second Why can’t we hear the earth spinning? We can’t feel Earth rotating because we’re all moving with it, at the same constant speed. Image via NASA.gov. Earth spins on […]
Is Vinegar an electrolyte?
Is Vinegar an electrolyte? Weak electrolytes are substances which only partially dissociate into ions when dissolved in water. Weak acids such as acetic acid, found in vinegar, and weak bases such as ammonia, found in cleaning products, are examples of weak electrolytes. Does lemon water replace electrolytes? Drinks with more electrolytes will help you stay […]
What part of bone is not covered by the periosteum?
What part of bone is not covered by the periosteum? What Is the Periosteum? The periosteum is a membranous tissue that covers the surfaces of your bones. The only areas it doesn’t cover are those surrounded by cartilage and where tendons and ligaments attach to bone. What is spongy bone called? Cancellous bone, also called […]
What is carbon cycle and its importance?
What is carbon cycle and its importance? The carbon cycle is important in ecosystems because it moves carbon, a life-sustaining element, from the atmosphere and oceans into organisms and back again to the atmosphere and oceans. Scientists are currently looking into ways in which humans can use other, non-carbon containing fuels for energy. What are […]
What are the 26 states of matter?
What are the 26 states of matter? The classical states of matter are usually summarised as: solid, liquid, gas, and plasma….Here is the list I will provide: Solid. Liquid. Gas. Plasma. Bose-Einstein Condensate. Excitonium. Degenerate Matter. Photonic Matter. Is a plasma compressible? Solids are non-compressible and have constant volume and constant shape. Liquids are non-compressible […]
Do lakes contain salt water?
Do lakes contain salt water? Most lakes contain freshwater. Closed lakes usually become saline, or salty. This is because as the water evaporates, it leaves behind solids—mostly salts. The Great Salt Lake, in the U.S. state of Utah, is the largest saline lake in North America. Why is Great Salt Lake 2 different colors? Explanation: […]

What happens to the molecules of solid liquid and gas when heated?
What happens to the molecules of solid liquid and gas when heated? All three states of matter (solid, liquid and gas) expand when heated. The atoms themselves do not expand, but the volume they take up does. When a solid is heated, its atoms vibrate faster about their fixed points. Molecules within gases are further […]
How do you convert frequency to velocity?
How do you convert frequency to velocity? These two relationships between frequency and wavelength (λ), and between frequency and velocity (v), bring us to the following frequency equation: f = v / λ . What is the velocity of a wavelength? The velocity of light, v, is the product of its wavelength, λ , and […]
