What are three main characteristics of an image of an object made by a plane mirror? Images formed by plane mirrors are virtual, upright, left-right reversed, the same distance from the mirror as the object’s distance, and the same size as the object. What are three main characteristics of an image? The three characteristics of […]
What is the difference between the two theories of relativity?
What is the difference between the two theories of relativity? The “General Theory of Relativity’ is related to gravity. It describes gravitational force as continuous non-spatial whole of space and time. The difference between the two theories is that the theory of general relativity throws light on the force of gravity with respect to curving […]
Which three factors affect soil formation?
Which three factors affect soil formation? Scientists attribute soil formation to the following factors: Parent material, climate, biota (organisms), topography and time. How time affects soil formation? Weathering Over Time: As each plant community over time progressively modifies parent material, organic material builds up and topsoils form. The succession of plant communities above the ground […]
Why does oxygen attract electrons more strongly than hydrogen?
Why does oxygen attract electrons more strongly than hydrogen? The oxygen atom attracts the shared electrons more strongly than the hydrogen atoms do because the nucleus of the oxygen atom has more positively charged protons. As a result, the oxygen atom becomes slightly negative in charge, and the hydrogen atoms become slightly positive in charge. […]
Is the black market a real place?
Is the black market a real place? A black market is often a place for the exchange of illicit and dangerous goods.

What is 1 dB?
What is 1 dB? Decibel (dB), unit for expressing the ratio between two physical quantities, usually amounts of acoustic or electric power, or for measuring the relative loudness of sounds. One decibel (0.1 bel) equals 10 times the common logarithm of the power ratio. What is black noise? Black noise is an informal term used […]
Which noble gas has the smallest atomic radius?
Which noble gas has the smallest atomic radius? Helium Why do noble gasses have no electronegativity? Electronegativity is the atom’s ability to attract electrons within a bond. Since noble gases already have a full valence shell of electrons and are stable, they have no need for attracting electrons so no, they do not have electronegativity. […]
