What temperature does quartz crack? Manufacturers market quartz as able to withstand temperatures up to 400 degrees Fahrenheit (one reason it works well as fireplace surrounds). But “thermal shock” can result from placing a hot pan straight from the oven or stovetop onto a cold quartz countertop, which can lead to cracking or discoloring. Can […]
What is gender socialization examples?
What is gender socialization examples? This gender socialization can be direct or indirect. For example, children learn about gender stereotypes through their peers’ direct comments (e.g., “long hair is for girls while short hair is for boys”) and/or negative reactions when failing to conform to their gender expectations. What are the factors that influence gender […]

How old is our oceans?
How old is our oceans? about 3.8 billion years Are oceans salty because of whale sperm? It’s all whale sperm. Everybody Google it. Because that’s why the water is salty. In fact, the saltiness “comes from many millions of years of water flowing over rocks and minerals,” according to oceanographer Simon Boxall. Which ocean has […]
What is the difference between dependent and independent variables?
What is the difference between dependent and independent variables? You can think of independent and dependent variables in terms of cause and effect: an independent variable is the variable you think is the cause, while a dependent variable is the effect. In an experiment, you manipulate the independent variable and measure the outcome in the […]
What does null hypothesis mean?
What does null hypothesis mean? The null hypothesis is a typical statistical theory which suggests that no statistical relationship and significance exists in a set of given single observed variable, between two sets of observed data and measured phenomena. What is the null hypothesis for at test? The null hypothesis remains the same for each […]
Do inductors pass AC?
Do inductors pass AC? The inductor stores electrical energy in the form of magnetic energy. The inductor does not allow AC to flow through it, but does allow DC to flow through it. What happens when AC is connected to capacitor? Once the capacitor is “fully-charged” the capacitor blocks the flow of any more electrons […]
How hot is electron beam welding?
What is amplitude frequency and phase?
What is amplitude frequency and phase? The Amplitude is the height from the center line to the peak (or to the trough). Or we can measure the height from highest to lowest points and divide that by 2. The Phase Shift is how far the function is shifted horizontally from the usual position. How do […]
Are slow oxidative fibers fatigue resistant?
Are slow oxidative fibers fatigue resistant? The three types of muscle fibers are slow oxidative (SO), fast oxidative (FO) and fast glycolytic (FG). Slow oxidative fibers use aerobic metabolism to produce low power contractions over long periods and are slow to fatigue. Which type of fiber is best if you need a quick burst of […]
