Which rock is classified as an evaporite? Minerals in evaporite rocks include carbonates (especially calcite, dolomite, magnesite, and aragonite), sulfates (anhydrite and gypsum), and chlorides (particularly halite, sylvite, and carnallite), as well as various borates, silicates, nitrates, and sulfocarbonates. Which of the following igneous rocks will cool the fastest? Extrusive igneous rocks form above the […]
How do electromagnetic fields affect the human body?
How do electromagnetic fields affect the human body? Low-frequency magnetic fields induce circulating currents within the human body. The strength of these currents depends on the intensity of the outside magnetic field. If sufficiently large, these currents could cause stimulation of nerves and muscles or affect other biological processes. How does frequency affect the human […]
How do I know if my steering rack is part of routine maintenance?
How do I know if my steering rack is part of routine maintenance? Checking the steering box A typical steering-box layout. Check the gasket and seals for leaks, and the moving parts for wear. Measure steering-wheel travel by making a chalk mark on the rim and using your finger as a reference point. Try to […]
What caused the Izmir earthquake 2020?
What caused the Izmir earthquake 2020? The magnitude 7.0 tremor occurred in an area of complex geological movement, where multiple tectonic plates crack the surface as they jostle for position. Rescue workers and locals search for residents trapped in the debris of a collapsed building in Izmir, Turkey, on October 30, 2020. Why did the […]
What is the Y intercept when given two points?
What is the Y intercept when given two points? Steps Calculate the slope from 2 points. For Example, Two points are (3, 5) and (6, 11) Substitute the slope(m) in the slope-intercept form of the equation. Substitute either point into the equation. You can use either (3,5) or(6,11). Solve for b, which is the y-intercept […]
What are emission spectrums used for?
What are emission spectrums used for? A spectroscope can be used to determine which frequencies have been emitted by a substance. The emission spectrum is a combination of the atomic spectra of the various kinds of atoms making up the substance and can be analyzed to determine the substance’s chemical or atomic composition. What do […]
Can sound waves bend?
Can sound waves bend? Sound waves do, indeed, bend. In an underwater thermal gradient the sonar waves can bend enough to create blind spots, so that you can not “see” a target that would ordinarily be well within sonar range. The other example is the difference in how well sound carries up/down wind. What is […]
What is the two main function of a diode?
What is the two main function of a diode? Main functions The most common function of a diode is to allow an electric current to pass in one direction (called the diode’s forward direction), while blocking it in the opposite direction (the reverse direction). As such, the diode can be viewed as an electronic version […]
Why is a decrease in GDP bad?
Why is a decrease in GDP bad? When GDP goes up, the economy is generally thought to be doing well. Meanwhile, weak growth signals that the economy is doing poorly. If GDP falls from one quarter to the next then growth is negative. This often brings with it falling incomes, lower consumption and job cuts. […]
What is the most important muscle?
What is the most important muscle? The human heart is the most incredible muscle in the body, beating about 100,000 times to send 3,600 gallons of blood through 75,000 miles of blood vessels each day. Sure, skeletal muscles are vital to our ability to function, but the heart is truly a step above. What muscle […]
