What are the 3 main heart arteries? Left Main Coronary Artery (also called the left main trunk) Circumflex artery. Left Anterior Descending artery (LAD) What is the main heart artery? The aorta (the main blood supplier to the body) branches off into two main coronary blood vessels (also called arteries). These coronary arteries branch off […]
Can you drive through a yellow light?
Can you drive through a yellow light? There is no law in California that forbids drivers from being in an intersection during a yellow light. The law is that the driver cannot be in the intersection during a red light. Where is a flashing yellow light used? A flashing yellow light tells you to slow […]
Do human bodies have frequencies?
Do human bodies have frequencies? According to the existing research, the natural frequency of a human-standing body is about 7.5 Hz, and the frequency of a sitting posture in the cab is generally 4–6 Hz. The natural frequency of the main body parts is shown in Table 1. The main part of the human body […]
Why could Wegener not answer objections?
Why could Wegener not answer objections? Explanation: Because he could not explain a mechanism that would cause the Earths’ crustal plates to shift around, his idea was dismissed at the time. He also had rates of movements for his continents that seemed very unlikely – too high. What was the major problem with Wegener’s ideas? […]
Does alcohol kill brain cells?
Does alcohol kill brain cells? Alcohol doesn’t kill brain cells, but it does have both short- and long-term effects on your brain, even in moderate amounts. Going out for happy hour a few nights a month likely won’t cause any long-term damage. But if you find yourself drinking heavily or binge drinking often, consider reaching […]
What is Brewster formula?
What is Brewster formula? Brewster Law Formula We express the relation for polarising angle formula as μ = tan ip. Here, μ refers to the refractive index of transparent medium. ip is the polarizing angle of incidence or a Brewster angle. What causes birefringence? Stress birefringence results when isotropic materials are stressed or deformed (i.e., […]
What is the mean free path of a molecule?
What is the mean free path of a molecule? Mean free path, average distance an object will move between collisions. The actual distance a particle, such as a molecule in a gas, will move before a collision, called free path, cannot generally be given because its calculation would require knowledge of the path of every […]
Which type of heat pump does not require a defrost cycle?
How does temperature affect a gas?
How does temperature affect a gas? The temperature of the gas is proportional to the average kinetic energy of its molecules. Faster moving particles will collide with the container walls more frequently and with greater force. If the temperature of the gas is measured on the Kelvin scale , the pressure is proportional to the […]
What is Rydberg equation used for?
What is Rydberg equation used for? The Rydberg formula is a mathematical formula used to predict the wavelength of light resulting from an electron moving between energy levels of an atom. What is red work formula? The Rydberg formula is the mathematical formula to determine the wavelength of light emitted by an electron moving between […]
