What does an alpha level of .05 mean? What Is the Significance Level (Alpha)? The significance level, also denoted as alpha or α, is the probability of rejecting the null hypothesis when it is true. For example, a significance level of 0.05 indicates a 5% risk of concluding that a difference exists when there is […]

What three factors affect the formation of magma? What three factors affect the formation of magma? Pressure, water, and temperature. What are the formation of […]
Why is the reverse bias current extremely small?
Why is the reverse bias current extremely small? When a diode is reverse biased, the width of the depletion region increases. Minority carriers of each material are pushed through the depletion zone to the junction. This action causes a very small leakage current to occur. What is the reverse breakdown voltage of a diode? Reverse […]
How do you prove a rhombus is a quadrilateral?
How do you prove a rhombus is a quadrilateral? To prove a quadrilateral is a rhombus, here are three approaches: 1) Show that the shape is a parallelogram with equal length sides; 2) Show that the shape’s diagonals are each others’ perpendicular bisectors; or 3) Show that the shape’s diagonals bisect both pairs of opposite […]
Which property could Huygens not prove?
Which property could Huygens not prove? Because, while Huygens’ was correct, he could not demonstrate that light acted as a wave, while the double-slit experiment shows this very clearly. Since light has relatively short wavelengths, to show wave effects it must interact with something small — Young’s small, closely spaced slits worked. What is Hydance […]
How do you know charges of elements?
Do positive and negative charges cancel?
Do positive and negative charges cancel? In Gauss’s Law for electric fields it’s the net flux that matters and an equal amount of positive and negative charge will cancel. In everyday life pretty much everything appears to lack any kind of charge despite being made up largely by particles that do have charge. How can […]
