How do you know if two lines have the same velocity? Therefore, if the slope of the blue line is the same as the slope of the red line, then regardless of their relative positions on the graph, they have the same velocity. Does same position mean same velocity? So the slope of a position […]
Is radioactivity a spontaneous process?
Is radioactivity a spontaneous process? Radioactive decay is by definition a spontaneous process in which the nuclei of unstable isotopes emit radiation as they are converted to more stable nuclei. All the decay processes occur spontaneously, but the rates at which different isotopes decay vary widely. Does spontaneous mean random? As adjectives the difference between […]
What are causes of ocean acidification?
What are causes of ocean acidification? Ocean acidification is mainly caused by carbon dioxide gas in the atmosphere dissolving into the ocean. This leads to a lowering of the water’s pH, making the ocean more acidic. Many factors contribute to rising carbon dioxide levels. What happens during ocean acidification? When carbon dioxide (CO2) is absorbed […]
How electric and magnetic fields are produced?
How electric and magnetic fields are produced? Electric fields are produced by electric charges, and magnetic fields are produced by the flow of electrical current through wires or electrical devices. Because of this, low frequency EMR is found in close proximity to electrical sources such as power lines. What is the difference between electric fields […]
Why is Aluminium ductile in terms of structure?
Why is Aluminium ductile in terms of structure? The energy is transferred throughout the rest of the metal by the moving electrons. Metals are described as malleable (can be beaten into sheets) and ductile (can be pulled out into wires). This is because of the ability of the atoms to roll over each other into […]
What are 5 uses of neon?
What are 5 uses of neon? Neon is also used to make high-voltage indicators and switching gear, lightning arresters, diving equipment and lasers. Liquid neon is an important cryogenic refrigerant. It has over 40 times more refrigerating capacity per unit volume than liquid helium, and more than 3 times that of liquid hydrogen. What happens […]
What do the rows mean on a periodic table?
What do the rows mean on a periodic table? Each row represents one period; the period number of an element indicates how many of its energy levels house electrons. Sodium, for instance, sits in the third period, which means a sodium atom typically has electrons in the first three energy levels. How do you identify […]
What is the difference between average acceleration and instantaneous acceleration?
What is the difference between average acceleration and instantaneous acceleration? Average acceleration is the change of velocity over a period of time. Instantaneous acceleration is the change of velocity over an instance of time. What’s the definition of instantaneous speed? Definition: When the speed of an object is constantly changing, the instantaneous speed is the […]
What charge do humans have?
What charge do humans have? Resting cells are negatively charged on the inside, while the outside environment is more positively charged. This is due to a slight imbalance between positive and negative ions inside and outside the cell. Cells can achieve this charge separation by allowing charged ions to flow in and out through the […]
Is PCl3 covalent or ionic?
Is PCl3 covalent or ionic? PCl3 has distorted structure due to the presence of lone pairs of electrons. (A) PCl3 Is contains three covalent bond which are formed by equal sharing of electron in between phosphorus atom and chlorine atom, hence it’s a covalent molecule. Does PCl3 contain ionic bonds? Phosphorus trichloride. Covalent bonding. Strong […]
