What are four ways that waves interact with matter? Waves interact with matter in several ways. The interactions occur when waves pass from one medium to another. The types of interactions are reflection, refraction, and diffraction. Each type of interaction is described in detail below. What is the measure of energy in a wave? Amplitude […]
What technology is on the moon?
What technology is on the moon? Other technologies like breathing apparatuses, fabric structures, communications and protective coatings that made man’s step on the Moon possible soon led to giant leaps in technology on Earth. What technology has NASA given us? Health and medicine Infrared ear thermometers. Ventricular assist device. LASIK. Cochlear implants. Artificial limbs. Light-emitting […]
Is nuclear power bad for the environment?
Is nuclear power bad for the environment? “Nuclear energy has perhaps the lowest impact on the environment — including air, land, water, and wildlife — of any energy source. It produces no harmful greenhouse gases, isolates its waste from the environment, and requires less area to produce the same amount of electricity as other sources. […]
How did Pangea split?
How did Pangea split? Scientists believe that Pangea broke apart for the same reason that the plates are moving today. The movement is caused by the convection currents that roll over in the upper zone of the mantle. About 200 million years ago Pangaea broke into two new continents Laurasia and Gondwanaland. Which era did […]
What are seasons caused by?
What are seasons caused by? Seasons occur because Earth is tilted on its axis relative to the orbital plane, the invisible, flat disc where most objects in the solar system orbit the sun. Earth’s axis is an invisible line that runs through its center, from pole to pole. Earth rotates around its axis. What causes […]

Does Fresno have snow? Fresno gets some kind of precipitation, on average, 48 days per year. Precipitation is rain, snow, sleet, or hail that falls to the ground….Climate […]
What is the most common rock found in Canada?
What is the most common rock found in Canada? Igneous rock (granite, gneiss) forms when molten rock cools. The Canadian Shield’s igneous base abounds in copper, gold, iron, and nickel. Sedimentary rock (sandstone, limestone) consists of hardened layers of rock particles. Beneath the Prairies, sedimentary layers store oil, gas, and coal. What are the major […]
Which brand of AA battery lasts the longest?
Which brand of AA battery lasts the longest? Energizer Ultimate Lithium Can I use AA batteries instead of AAA? All the same voltage, so all can substitute for each other. Larger cells just sag less and last longer. Do 18650 batteries explode? The safety problem of 18650 lithium-ion battery is burning or even exploding. The […]
Why does frequency affect wavelength?
Why does frequency affect wavelength? 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 gets longer. […]
Which color model is best suited for human interpretation?
Which color model is best suited for human interpretation? The HSI Color Model HSI stands for hue, saturation, intensity. This model is interesting because it can initially seem less intuitive than the RGB model, despite the fact that it describes color in a way that is much more consistent with human visual perception. What does […]
