Is the water displacement method accurate? The change in water level equals the volume of the submerged object. This method is more accurate than measuring water that has spilled out an overflowing beaker. You may need to remind students of the need for accuracy, not only in the weighing of the objects, but also in […]
What happens to wavelength of energy increases?
What happens to wavelength of energy increases? The number of complete wavelengths in a given unit of time is called frequency (f). As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength […]
Is it bad to leave a basketball in a hot car?
Is it bad to leave a basketball in a hot car? If you expose your basketball to the elements for too long, eventually they will expose your basketball. Rain or shine, hot or cold, neither indoor or outdoor basketballs should be left outside in extreme conditions. Any type of wetness can ruin the quality of […]
What are examples of Geosphere?
What are examples of Geosphere? Examples are all the rocks and sand particles from dry land to those found at the bottom of the oceans. They also include the mountains, minerals, lava and molten magma from beneath the earth’s crust. The geosphere undergoes infinite processes constantly and that, in turn, modifies other spheres. What are […]
How can I temporarily fix my car window?
How can I temporarily fix my car window? Create A Temporary Window On the outside window, stretch a piece of clear tape from the top of the window to the bottom. Continue to layer pieces of tape across the window. A clear, temporary “window” begins to take shape. Repeat until the area is covered. Follow […]
Is it safe to heat magnets?
Is it safe to heat magnets? When heated above 176° Fahrenheit (80° Celsius), magnets will quickly lose their magnetic properties. The magnet will become permanently demagnetized if exposed to these temperatures for a certain length of time or heated at a significantly higher temperature (Curie temperature). Why Does heat destroy magnets? Excessive heat causes atoms […]
Which best explains how photosynthesis is helpful to humans?
Which best explains how photosynthesis is helpful to humans? Which best explains how photosynthesis is helpful to humans? It reduces the amount of harmful rays released by the sun. It increases the levels of carbon dioxide in the air. What reactants are needed for photosynthesis and respiration? While photosynthesis requires carbon dioxide and releases oxygen, […]
What is the use of resonant frequency?
What is the use of resonant frequency? Chapter 6 – Resonance One use for resonance is to establish a condition of stable frequency in circuits designed to produce AC signals. Usually, a parallel (tank) circuit is used for this purpose, with the capacitor and inductor directly connected together, exchanging energy between each other. What are […]
Does Wile E Coyote ever talk?
Does Wile E Coyote ever talk? Speech. Coyote usually does not make a sound, unlike Road Runner, who gives off the occasional “meep, meep.” Instead, Coyote communicates with signs that display his emotion, such as “ouch” or “uh-oh.” He has been known to talk, however, when he is around Bugs Bunny (In that case, Coyote […]
