Can a vector has infinite components? A vector can be split into infinite components (but only 3 orthogonal ones) Are vectors one dimensional? Yes. Not only are one dimensional vectors a thing, “zero dimensional” vectors are too! An example of a one dimensional vector would just be any real number, as you observed. How do […]
What do theories and laws have in common?
What do theories and laws have in common? As previously stated, a scientific theory is a well-substantiated explanation of some aspect of the natural world. A scientific law is simply an observation of the phenomenon that the theory attempts to explain. The theory of gravity is the explanation as to why the apple falls to […]
How do you handle a patient with hypovolemic shock?
How do you handle a patient with hypovolemic shock? Treatment revolves around controlling loss of fluid and blood, replacing what’s been lost, and stabilizing damage that both caused and resulted from the hypovolemic shock. This will also include treating the injury or illness that caused the shock, if possible. These include: blood plasma transfusion. Which […]
Can you rotate your body in mid air?
Can you rotate your body in mid air? One cannot change one’s angular momentum in mid-air, other than by interaction with the air. A sky-diver, falling through the air after the first few seconds, is falling at “terminal velocity”. Can you rotate in the air? Jump into the air, you can turn your body. Physicists […]
When light interacts with matter 3 things can happen?
When light interacts with matter 3 things can happen? Light can interact with matter in three ways: absorption, transmission, and reflection. 1. ABSORPTION – When a light wave with a identical frequency to an electron’s natural frequency “impinges” upon an atom, the electrons will begin to vibrate as a result (almost like they are “set […]
Why do planes fly over water instead of land?
Why do planes fly over water instead of land? At lower levels, being over sea would typically offer less turbulence, in part because as the ground warms you can encounter rising air thermals. Generally, airliners fly whatever route provides the shortest time, which is not always the shortest distance, often called the Great Circle route. […]
What is relative term in physics?
What is relative term in physics? A relative term is a term that makes two or more distinct references to objects (which may be the same object, for example in “The Morning Star is the Evening Star”). Is there anything called absolute motion? A body cannot exist at a state of absolute rest or absolute […]
Which best describes the relationship between brightness B and distance d )?
Which best describes the relationship between brightness B and distance d )? Inverse Square Law of Brightness The Apparent Brightness (B) of a source is inversely proportional to the square of its distance (d): Implications: It will appear 22=4 times brighter. Which type of dwarf is largest? A typical white dwarf is about as massive […]
What two properties of water make capillary action possible?
What two properties of water make capillary action possible? Capillary action occurs because water is sticky, thanks to the forces of cohesion (water molecules like to stay close together) and adhesion (water molecules are attracted and stick to other substances). Why is capillary action important to life? Capillary action is important for moving water around. […]
