What is the L quantum number? The angular quantum number (l) describes the shape of the orbital. Orbitals have shapes that are best described as spherical (l = 0), polar (l = 1), or cloverleaf (l = 2). They can even take on more complex shapes as the value of the angular quantum number becomes […]
What does the placenta sound like on a Doppler?
What does the placenta sound like on a Doppler? Whenever you use a doppler, you’ll hear a variety of sounds depending on where it’s placed. A “whooshing” sound usually indicates either placenta or movement. Some people also describe the noise as similar to that of blowing trees. This should not be mistaken for a baby’s […]
What is minimum power speed?
What is minimum power speed? The velocity for minimum power is obtained by taking the derivative of the equation for Preq with respect to V and setting it equal to zero. As we will see shortly, maximum endurance (time aloft) occurs when the minimum power is used to maintain steady level flight. Is 255 volts […]
Does anti glare coating wear off?
Does anti glare coating wear off? The average AR coating should last about 2 years in my experience under moderate temperature and cleaning abuse,but if you are exposing your glasses to more extremes they could break down within a few months. Can I put anti glare on my glasses myself? Can I Add Anti-Reflective Coating […]
What is a join between atoms called?
What is a join between atoms called? When two electrons are shared between two neighbouring atoms, they are said to be joined by a covalent bond. When covalent bonds form between atoms, the resulting entity is called a molecule with a fixed characteristic geometry. What is the basic unit of matter? In turn, the atom […]
What is range of normal distribution?
What is range of normal distribution? The area under each curve is one but the scaling of the X axis is different. Note, however, that the areas to the left of the dashed line are the same. The BMI distribution ranges from 11 to 47, while the standardized normal distribution, Z, ranges from -3 to […]
What is the most dangerous indoor air pollution?
What is the most dangerous indoor air pollution? Cigarette Smoke What are the most threatening indoor air pollutants? The six most dangerous indoor air pollutants are: Asbestos. Carbon Monoxide. Lead. Mold. Radon. Volatile Organic Compounds (VOCs) What are the most harmful air pollutants? Pollen. Mold. Lead. Volatile Organic Compounds (VOCs) Carbon Monoxide (CO) Ozone (O3) […]
Does aluminum or lead have a greater buoyant force?
Does aluminum or lead have a greater buoyant force? Insight: Although each sphere experiences the same buoyant force, the lead sphere is more massive than the aluminum sphere and therefore the lead sphere still weighs more while submerged than does the aluminum sphere. Is lead buoyant? The specific gravity of lead is 11.34 – which […]
What happens if you triple the distance between two objects?
What happens if you triple the distance between two objects? If the separation distance between any two objects is tripled (increased by a factor of 3), then the force of gravitational attraction is decreased by a factor of 9 (3 raised to the second power). What is the formula of gravitational force? The mathematical formula […]
What is the significance of quantum number?
What is the significance of quantum number? Quantum numbers are important because they can be used to determine the electron configuration of an atom and the probable location of the atom’s electrons. Quantum numbers are also used to understand other characteristics of atoms, such as ionization energy and the atomic radius. Which of the following […]
