What statistics we use to compare the center and spread of data sets? Correct answer: The most common measures of center are the mean and median. The mean represents the arithmetic average of a set and the median is the middlemost value. On the other hand, the most common measures of spread are the mean […]
What time period is SHM?
Why can you safely handle a 1.5 V battery without being electrocuted?
Why can you safely handle a 1.5 V battery without being electrocuted? Explanation: If 1.5 volt is applied to your body the current will be negligible.It will not electrocute a person.. So you can safely handle 1.5 volt battery. What is the current of 1.5 V battery? practically impossible. Normal AA/AAA batteries that have a […]
What do you mean by dielectrics?
What do you mean by dielectrics? Dielectric, insulating material or a very poor conductor of electric current. When dielectrics are placed in an electric field, practically no current flows in them because, unlike metals, they have no loosely bound, or free, electrons that may drift through the material. What is dielectrics and its types? Dielectrics […]
What causes a quartz clock to run fast?
What causes a quartz clock to run fast? Please note that your clock might run faster than design just because of electric interference such as spikes that get counted as oscillations on top of those from quartz. This is the reason why quartz clocks might go faster but they will never slow down. The frequency […]
What is the radius of curvature of a mirror?
What is added in water to kill germs?
What is added in water to kill germs? Chlorination is the process of adding chlorine to drinking water to kill parasites, bacteria, and viruses. Why are sodium and chlorine more active elements? Answer. Explanation: It takes more energy to remove an electron from a sodium atom to form an Na+ ion than we get back […]
What affects boiling point of water?
What affects boiling point of water? Atmospheric pressure influences the boiling point of water. When atmospheric pressure increases, the boiling point becomes higher, and when atmospheric pressure decreases (as it does when elevation increases), the boiling point becomes lower. Pressure on the surface of water tends to keep the water molecules contained. Can a tea […]
What are trends in modern periodic table?
What are trends in modern periodic table? Periodic trends are specific patterns in the properties of chemical elements that are revealed in the periodic table of elements. Major periodic trends include electronegativity, ionization energy, electron affinity, atomic radii, ionic radius, metallic character, and chemical reactivity. What is the main use of Livermorium? At present, it […]
How did urbanization change society?
How did urbanization change society? Some of the negative effects of urbanization included crowded, unsanitary living conditions for workers, as well as corrupt municipal, or city, politics. Urbanization was aided by new technologies in transportation, architecture, utilities, and sanitation. In addition, cities offered new cultural opportunities. How did urbanization contribute to living conditions? The growth […]
