What are the characteristics of plants that can survive in the tundra? The features which make it able to survive are: low-lying – the snow covers it in winter which helps insulate it. seeds that scatter in the wind. narrow leaves helping to reduce transpiration. adapted to a short growing season (so has a short […]
What are the 4 components of body mechanics?
What are the 4 components of body mechanics? Elements of Body Mechanics It involves the basic elements of body alignment (posture), balance, and coordinated movement. What are the 6 principles of body mechanics? Maintain Proper Body Alignment. Tuck in your buttocks. Pull your abdomen in and up. Keep your back flat. Keep your head up. […]
What happens if atmospheric pressure is too high?
What happens if atmospheric pressure is too high? As the pressure decreases, the amount of oxygen available to breathe also decreases. At very high altitudes, atmospheric pressure and available oxygen get so low that people can become sick and even die. What is considered high pressure weather? A barometer reading of 30 inches (Hg) is […]
What proves a permanent magnet?
What proves a permanent magnet? A high magnetic ordering temperature (called the “Curie temperature” or Tc), below which the material is spontaneously magnetic. A large remanent magnetic flux (called “remanence” or Br) maintained in the absence of an external magnetic field. A strong resistance to demagnetization (called “coercivity” or Hc) What is the strength of […]
How do you trick a motion sensor?
How do you trick a motion sensor? Most motion detectors, even newer ones, use infrared to detect significant changes in the surrounding room’s temperature, Porter said. Normally, walking around in a room would set off these sensors, but using something as simple as a piece of styrofoam to shield your body can trick them, he […]
Who said light is a particle?
Who said light is a particle? Einstein Who discovered the particle nature of light? The mathematical theory of electromagnetism by James Clerk Maxwell, set up in 1864, led to the view that light is of electromagnetic nature, propagating as a wave from the source to the receiver. Heinrich Hertz discovered experimentally the existence of electromagnetic […]
What is say is a path of electricity one word answer?
What is say is a path of electricity one word answer? An electric circuit is a path in which electrons from a voltage or current source flow. The point where those electrons enter an electrical circuit is called the “source” of electrons. Is a closed path that allows electricity to flow from one point to […]
What is reverse causality example?
What is reverse causality example? According to Katz (2006), identifying reverse causality is sometimes a matter of “common sense.” For example, a study might find that brown spots on the skin and sunbathing are linked. While it is plausible that sunbathing can cause brown skin spots, it’s highly unlikely that the brown spots cause sunbathing. […]
What results when two atoms share electrons?
What results when two atoms share electrons? A covalent bond results when two atoms share electrons. In the case of two hydrogen atoms, each shares its single electron with the other. This sharing allows each to fill its electron shell with two electrons. The pair of shared electrons constitutes a covalent single bond. How many […]
What does the shape of a route sign tell you?
What does the shape of a route sign tell you? These signs are square or rectangular shaped, and are blue with white let ters or symbols. They show the location of various services; such as rest areas, gas stations, campgrounds or hospitals. The shape of route signs indicate the type of road- way, interstate, U.S., […]
