How rare is a fireball? This may sound like a long time, but good data has been collected on only about 800 fireballs so far. Of these, only 4 have been recovered on the ground as meteorites. A meteorite-causing fireball is very rare and must be at least magnitude -8 to have sufficient mass to […]
What are the 3 types of lubricants?
What are the 3 types of lubricants? There are three main types of lubricants: oil-based, water-based, and silicone-based. The best lubricant for women depends on their needs. What lube lasts the longest? Coconut Oil What solid lubricant is best? PTFE and graphite are well known as good solid lubricants. They wear off from the friction […]
What are the two end products of aerobic respiration?
What are the two end products of aerobic respiration? End products of aerobic respiration are carbon dioxide, water and energy in the form of (38) ATP. What is the importance of cellular respiration in our everyday life? The Purpose Cellular Respiration Cellular respiration is the process by which cells in plants and animals break down […]
Which two protists are animal-like?
Which two protists are animal-like? Animal-like protists include the flagellates, ciliates, and the sporozoans. Which protist moves a whip like tail? Flagellum Do diatoms have a whip-like tail? Diatoms are single-celled algae that have chloroplasts and can undergo photosynthesis. Dinoflagellates are also single-celled but they have two whip-like tails called “flagella.” Although many dinoflagellates also […]
How is ionosphere important for us?
How is ionosphere important for us? the ionosphere is important because it reflects and modifies radio waves used for communication and navigation. Other solar phenomena, such as flares, and changes in the solar wind and geomagnetic storms also effect the charging of the ionosphere. How high up is the ionosphere? about 48 kilometers Is the […]

Work Power Work can also be measured in units like electron volt (eV), kWh, MWh, and GWh. Energy is also measured in units like […]
What three forms can Acid Precipitation take?
What three forms can Acid Precipitation take? What three forms can acid precipitation take? Rain, sleet, or snow. What is the formula of acid rain? “Clean” or unpolluted rain has an acidic pH, but usually no lower than 5.7, because carbon dioxide and water in the air react together to form carbonic acid, a weak […]
Why do sound waves move faster through the ground than through the air?
Why do sound waves move faster through the ground than through the air? Particles of matter are packed more tightly in the ground than in the air. The reason is that sound waves are vibrations of the molecules of the medium: therefore, if the particles of the medium are closer together (as in solids), the […]
How do we usually think of voltage as the cause and current as the effect?
How do we usually think of voltage as the cause and current as the effect? Voltage is the Cause, Current is the Effect Voltage attempts to make a current flow, and current will flow if the circuit is complete. Voltage is sometimes described as the ‘push’ or ‘force’ of the electricity, it isn’t really a […]
