Is it OK to sleep with plants in your bedroom?
Is it OK to sleep with plants in your bedroom? While many plants release carbon dioxide, not oxygen, at night, having a few plants in the bedroom will not release enough carbon dioxide to be harmful at all. Also, not all plants release carbon dioxide at night. With proper plant selection, growing houseplants in bedrooms […]
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 […]
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 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 […]
What are the 2 general types of waves?
What are the 2 general types of waves? Waves come in two kinds, longitudinal and transverse. Transverse waves are like those on water, with the surface going up and down, and longitudinal waves are like of those of sound, consisting of alternating compressions and rarefactions in a medium. What type of wave is light? Light […]
What kind of a wave is sound?
What kind of a wave is sound? These particle-to-particle, mechanical vibrations of sound conductance qualify sound waves as mechanical waves. Sound energy, or energy associated with the vibrations created by a vibrating source, requires a medium to travel, which makes sound energy a mechanical wave. How ECHO is created? An echo is made by sound […]
