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 […]
At what temperature does road salt become ineffective?
At what temperature does road salt become ineffective? 10 degrees Is 34 degrees too cold for plants? Frost Advisory – This is when the temperature is expected to fall to 36 degrees to 32 degrees Fahrenheit. Light freeze – 29° to 32° Fahrenheit will kill tender plants. Moderate freeze – 25° to 28° Fahrenheit is […]

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 […]
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. […]
What is the formula for calculating electrical load?
What is the formula for calculating electrical load? Compare the wattage of your air conditioner and furnace. Since you only use one at a time, add only the larger wattage rating to your equation. Divide the resulting number of watts by volts (most homes use 220 volts) to get the number of amps, or the […]
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. […]
Is it OK to take 2 rest days in a row?
Why do we reject the null hypothesis when the p-value is small?
Why do we reject the null hypothesis when the p-value is small? A p-value less than 0.05 (typically ≤ 0.05) is statistically significant. It indicates strong evidence against the null hypothesis, as there is less than a 5% probability the null is correct (and the results are random). Therefore, we reject the null hypothesis, and […]
