How do you determine the state of matter in a chemical equation? Notation for a Chemical Equation The state of matter of each compound or molecule is indicated in subscript next to the compound by an abbreviation in parentheses. For example, a compound in the gas state would be indicated by (g), solid (s), liquid […]
What is the correct pathway of light through the eye?
What is the correct pathway of light through the eye? Light passes through the front of the eye (cornea) to the lens. The cornea and the lens help to focus the light rays onto the back of the eye (retina). The cells in the retina absorb and convert the light to electrochemical impulses which are […]
What two species are involved in Commensalism?
What two species are involved in Commensalism? Commensalism is a type of relationship between two living organisms in which one organism benefits from the other without harming it. A commensal species benefits from another species by obtaining locomotion, shelter, food, or support from the host species, which (for the most part) neither benefits nor is […]
Why can humans not fly?
Why can humans not fly? Humans will never fly by flapping our arms with wings attached, says Mark Drela, Terry J. Kohler Professor of Fluid Dynamics in the Department of Aeronautics and Astronautics. The arms and chest of a human do not have anywhere near enough muscle mass to provide the necessary power. What are […]
Is threshold frequency the same for all metals?
Is threshold frequency the same for all metals? Different metals have different values of work function because of difference in their electronegativity. The frequency of the photon with energy equal to work function is called threshold frequency. The value of photocurrent depends on the intensity of the falling radiation. Why is there a threshold frequency? […]
What is the radius of the first Bohr orbit in He+?
What is the adiabatic equation?
What is the adiabatic equation? The normally used equation is the so-called adiabatic equation. For a given fault of I, which lasts for time t, the minimum required cable cross-sectional area is given by: A=√I2tk. where: A – the nominal cross-section area, mm2. I – the fault current in, A. What is work done in […]
What are three factors that often change at a front?
What are three factors that often change at a front? Fronts Sharp temperature changes over a relatively short distance. Change in moisture content. Rapid shifts in wind direction. Pressure changes. Clouds and precipitation patterns. Which front is not a standard weather front? The correct answer is a. cool front. The other answers are all examples […]
What is the most dangerous mutation?
What is the most dangerous mutation? Insertion or deletion results in a frame-shift that changes the reading of subsequent codons and, therefore, alters the entire amino acid sequence that follows the mutation, insertions and deletions are usually more harmful than a substitution in which only a single amino acid is altered. What are examples of […]
What is the magnitude of a displacement?
What is the magnitude of a displacement? Magnitude of displacement is equal to the absolute value of the displacement vector. In physical sense, the magnitude of displacement is equal to the linear distance between initial and final positions along the straight line joining two positions i.e. the shortest distance between initial and final positions. Does […]
