What does shear stress do to rocks? Shearing in rocks. The white quartz vein has been elongated by shear. When stress causes a material to change shape, it has undergone strain or deformation. Deformed rocks are common in geologically active areas. What is the deformation caused by stress? There are three types of stress: compression, […]
Can we go below 0 Kelvin?
Can we go below 0 Kelvin? Summary: On the absolute temperature scale, which is used by physicists and is also called the Kelvin scale, it is not possible to go below zero – at least not in the sense of getting colder than zero kelvin. At zero kelvin (minus 273 degrees Celsius) the particles stop […]
What is the pH of alkaline solutions?
What is the pH of alkaline solutions? Introduction to pH – acidic and basic (alkaline) pH Ion Concentration (gram equivalent per liter) Type of Solution 6 0.000001 Acid Solution – Hydrogen ions – H+ 7 0.0000001 Neutral Solution (pure neutral water) 8 0.000001 Basic (alkaline) Solution – Hydroxide ions – OH- 9 0.00001 How do […]
What are the causes of bad posture?
What are the causes of bad posture? Common causes of bad posture Pain or past injuries. When you experience pain in your back or neck muscles or any other part of the body, you tend to overcome the pain by holding your body in a different position. Low nutritional state. Hereditary. Extra weight. Habit. Your […]
Can you pressure cook and then slow cook?
Can you pressure cook and then slow cook? It’s no surprise that pressure cooking is faster than slow cooking, but did you know that you can get the same fall-apart tender results using a fraction of the energy too? Cooking Temperature – Get the same results faster! … Which is the best pressure cooker to […]
Can an object gain or lose neutrons?
Is phyletic gradualism real?
Is phyletic gradualism real? Phyletic gradualism is a model of evolution which theorizes that most speciation is slow, uniform and gradual. When evolution occurs in this mode, it is usually by the steady transformation of a whole species into a new one (through a process called anagenesis). Who proposed gradualism and punctuated equilibrium? The idea […]
How do you calculate the capacitance of an AC circuit?
How do you calculate the capacitance of an AC circuit? The relationship between this charging current and the rate at which the capacitors supply voltage changes can be defined mathematically as: i = C(dv/dt), where C is the capacitance value of the capacitor in farads and dv/dt is the rate of change of the supply […]
What is the role of water in noncyclic electron flow?
What is the role of water in noncyclic electron flow? What is the purpose of water in the noncyclic flow of electrons in photosynthesis? water splits, thus giving electrons to P680 and having 2 hydrogen ions and one oxygen atom. This all releases O2. What is the difference between noncyclic and cyclic electron flow? Non-cyclic […]
