Why do planes fly over water instead of land? At lower levels, being over sea would typically offer less turbulence, in part because as the ground warms you can encounter rising air thermals. Generally, airliners fly whatever route provides the shortest time, which is not always the shortest distance, often called the Great Circle route. […]

What two properties of water make capillary action possible?
What two properties of water make capillary action possible? Capillary action occurs because water is sticky, thanks to the forces of cohesion (water molecules like to stay close together) and adhesion (water molecules are attracted and stick to other substances). Why is capillary action important to life? Capillary action is important for moving water around. […]
What are the causes and effects of eutrophication?
What are the causes and effects of eutrophication? “Eutrophication is an enrichment of water by nutrient salts that causes structural changes to the ecosystem such as: increased production of algae and aquatic plants, depletion of fish species, general deterioration of water quality and other effects that reduce and preclude use”. What can humans do to […]
What increases when frequency increases?
What increases when frequency increases? From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer. There are two basic types of waves: mechanical and electromagnetic. What is the highest frequency ever generated? At least ~100 GeV, which corresponds to 2*1025 Hz. I […]
What are the possible sources of error in a bomb calorimetry experiment?
What are the possible sources of error in a bomb calorimetry experiment? Sources of error include the percent error in water measurement and incomplete vaporization of the nichrome wire. The internal volume of the Parr-bomb was measured to be 341mL. Why is benzoic acid used to calibrate a bomb calorimeter? Benzoic acid (C6H5CO2H) is often […]
How far from the wall is the foot of the ladder?
How far from the wall is the foot of the ladder? 22.56 feet What is the spacing between steps on a ladder? (i) Rungs, cleats, and steps of portable ladders (except as provided below) and fixed ladders (including individual rung/step ladders) shall be spaced not less than 10 inches (25 cm) apart, nor more than […]
Is cooking a chemical change?
Is cooking a chemical change? Rotting, burning, cooking, and rusting are all further types of chemical changes because they produce substances that are entirely new chemical compounds. For example, burned wood becomes ash, carbon dioxide, and water. An unexpected color change or release of odor also often indicates a chemical change. What type of chemical […]
