Does the Heisenberg uncertainty principle disprove determinism? Heisenberg’s uncertainty principle does not invalidate determinism. Heisenberg’s uncertainty principle relates the product of the standard deviations of the possible outcomes of two different types of measurements to each other[1][2]. Does quantum theory disprove determinism? The equations of quantum mechanics do not determine what will happen, but determine […]
What causes red fur on dogs?
What causes red fur on dogs? Red fur staining is caused by a compound called porphyrin. Porphyrins are iron-containing molecules produced when the body breaks down red blood cells. They are removed from the body primarily through feces, but are also in urine, tears and saliva. Why does my white dog’s skin turn pink? Your […]
What is the intensity of the light after it passes through the second polarizer?
What is the intensity of the light after it passes through the second polarizer? The intensity I of polarized light after passing through a polarizing filter is I = I0 cos2 θ, where I0 is the original intensity and θ is the angle between the direction of polarization and the axis of the filter. Polarization […]
How can you tell if something is quartz?
How can you tell if something is quartz? Quartz crystals rank as 7 on the Mohs scale. Therefore, a piece of quartz crystal will scratch a piece of glass. Test the unknown stone under inspection by trying to scratch a common piece of glass such as a glass bottle. If the object easily scratches the […]
How are water mills used today?
How are water mills used today? The most common use of water mills historically and in modern day developing countries is for grinding grains into flour. These are called gristmills, corn mills or flour mills. Early wheel design in ancient Greece and Rome employed horizontal paddles that were called Norse wheels. Can a water mill […]
How do I calculate change in velocity?
How do I calculate change in velocity? Multiply the acceleration by time to obtain the velocity change: velocity change = 6.95 * 4 = 27.8 m/s . Since the initial velocity was zero, the final velocity is equal to the change of speed. You can convert units to km/h by multiplying the result by 3.6: […]
Why do stars move when I stare at them?
Why do stars move when I stare at them? You’re absolutely right that stars twinkle — and sometimes appear to move around — due to our atmosphere “scrambling” their light as it travels from the top of Earth’s atmosphere to the ground. First, stars close to the horizon twinkle more because their light must travel […]
What are the characteristics of a groundwater?
What are the characteristics of a groundwater? Some of the most typical characteristics of groundwater are weak turbidity, a constant temperature and chemical composition and almost overall absence of oxygen. Circulating groundwater can have extreme variation in the composition with the appearance of pollutants and various contaminants. What is groundwater hydrology? Hydrogeology is the study […]
What is a parameter estimate?
What is a parameter estimate? Parameter estimates (also called coefficients) are the change in the response associated with a one-unit change of the predictor, all other predictors being held constant. The unknown model parameters are estimated using least-squares estimation. What is a population parameter give three examples? What is a population parameter? Give three examples. […]
Is potato an edible root?
Is potato an edible root? Common potatoes and sweet potatoes are both edible roots. The common potato (Solanum tuberosum) is an annual and a member of the nightshade family. More than 100 varieties are cultivated as food crops. Is potato a stem or root? Potatoes, grown in cooler climates or seasons around the world, are […]
