What is the relationship between S and P waves? P waves travel fastest and are the first to arrive from the earthquake. In S or shear waves, rock oscillates perpendicular to the direction of wave propagation. In rock, S waves generally travel about 60% the speed of P waves, and the S wave always arrives […]

What are 3 control variables?
What are 3 control variables? An experiment usually has three kinds of variables: independent, dependent, and controlled. The independent variable is the one that is changed by the scientist.

Do plants take oxygen out of water?
Do plants take oxygen out of water? Oxygen dissolves into water from two sources: the atmosphere and from plants in the water. In the presence of sunlight, these produce oxygen through photosynthesis and release this oxygen into the pond water. At night and on very cloudy days, algae and submerged plants remove oxygen from the […]
What causes capacitors to discharge?
What causes capacitors to discharge? If a path in the circuit is created, which allows the charges to find another path to each other, they’ll leave the capacitor, and it will discharge. For example, in the circuit below, a battery can be used to induce an electric potential across the capacitor. How fast do capacitors […]
Do egg cartons reduce sound?
Do egg cartons reduce sound? The various textural ripples and waves of egg carton-shaped materials do not absorb sound waves in their entirety. Instead, they break these sound waves up into multiple frequencies and echo them in various directions, which radically reduces the level of noise production and echo in your room. How can you […]

Is the ability of the heart lungs and blood vessels to deliver oxygen to your body tissues?
Is the ability of the heart lungs and blood vessels to deliver oxygen to your body tissues? Cardiovascular endurance is the ability of the heart, lungs and blood vessels to deliver oxygen to working muscles and tissues, as well as the ability of those muscles and tissues to utilize that oxygen over an extended period […]
What are 4 ways the periodic table is organized?
What are 4 ways the periodic table is organized? The periodic table of elements arranges all of the known chemical elements in an informative array. Elements are arranged from left to right and top to bottom in order of increasing atomic number. Order generally coincides with increasing atomic mass. What are the rows on the […]
What do all electromagnets have in common?
What do all electromagnets have in common? What do all electromagnetic waves have in common? They can travel at the speed of light. They have the same wavelengths. They travel only through matter. What are the 7 Colours of the spectrum? He coined the idea that there are seven colours in a spectrum: red, orange, […]
