What is the formula of parallax method? Parallax Formula: p = parallax angle in arcseconds. d = distance in “Parsecs” Writing our parallax formula in this way allows us to define a new “natural” unit for distances in astronomy: the Parallax-Second or Parsec. What is the purpose of parallax error? It is an error caused […]
What is the formula of resistance?
What is the formula of resistance? The electrical resistance of a circuit component or device is defined as the ratio of the voltage applied to the electric current which flows through it: If the resistance is constant over a considerable range of voltage, then Ohm’s law, I = V/R, can be used to predict the […]
What is the wavelength of photon emitted?
Is aquifer water safe to drink?
Is aquifer water safe to drink? Most of the time, U.S. groundwater is safe to use. However, groundwater sources can become contaminated with germs, such as bacteria, viruses, and parasites, and chemicals, such as those used in fertilizers and pesticides. Contaminated groundwater can make people sick. Water infrastructure requires regular maintenance. Does the water pass […]
What is called cohesive force?
What is called cohesive force? Cohesion, in physics, the intermolecular attractive force acting between two adjacent portions of a substance, particularly of a solid or liquid. It is this force that holds a piece of matter together. Intermolecular forces act also between two dissimilar substances in contact, a phenomenon called adhesion. Is cohesive a force? […]
Why do chloroplasts move from cell to cell?
Why do chloroplasts move from cell to cell? Chloroplasts migrate in response to different light intensities. Under weak light, chloroplasts gather at an illuminated area to maximize light absorption and photosynthesis rates (the accumulation response). In contrast, chloroplasts escape from strong light to avoid photodamage (the avoidance response). Why are chloroplasts found in plant cells […]
What does toasting do to bread?
What does toasting do to bread? Toasting bread also lowers the amount of fat in a toast. Though the fat in the bread will not be lowered significantly, it will definitely make a difference if you eat bread every day. Weight watchers should also choose toasted bread over raw bread. Can bread catch fire in […]
What is the psychiatric classification system?
What is the psychiatric classification system? The latest edition, DSM-5, published in 2013, provides a classification system that attempts to separate mental illnesses into diagnostic categories based on descriptions of symptoms (that is, what people say and do as a reflection of how they think and feel) and on the course of the illness. What […]
What will be the appearance of a TLC plate if a solvent of too low polarity is used for development?
What is better 50Hz or 60Hz?
What is better 50Hz or 60Hz? The primary difference between 50 Hz (Hertz) and 60 Hz (Hertz) is simply that 60 Hz is 20% higher in frequency. Lower the frequency, speed of induction motor and generator will be lower. For example with 50 Hz, generator will be running at 3,000 RPM against 3,600 RPM with […]
