How do you find the class interval in a frequency distribution? The steps in grouping may be summarized as follows: Decide on the number of classes. Determine the range, i.e., the difference between the highest and lowest observations in the data. Divide range by the number of classes to estimate approximate size of the interval […]
What kind of mixtures can be separated by distillation?
What kind of mixtures can be separated by distillation? Fractional distillation is a method for separating a liquid from a mixture of two or more liquids. For example, liquid ethanol can be separated from a mixture of ethanol and water by fractional distillation. This method works because the liquids in the mixture have different boiling […]
What does it mean when cats sit and stare at you?
What does it mean when cats sit and stare at you? If your cat looks relaxed and calm when staring at you, they’re looking at you for happy reasons and are likely just showing you affection. How do cats choose their human? Cats’ favoritism is just as unpredictable and individual. Your cat’s favorite person might […]
What does a sharp knife cut better than a blunt one?
What is needed for light independent reactions?
What is needed for light independent reactions? After the energy from the sun is converted and packaged into ATP and NADPH, the cell has the fuel needed to build carbohydrate molecules. These energy-carrying molecules travel into the stroma where the Calvin cycle reactions take place. … What is an example of light independent reactions? Explanation: […]
What are 3 examples of physical weathering?
What are 3 examples of physical weathering? Some examples of physical weathering mechanisms: Frost wedging. Frost wedging happens when water filling a crack freezes and expands (as it freezes, water expands 8 to 11% in volume over liquid water). Heat/Cold Cycles. Unloading. What are 4 types of physical weathering? Four Types of Physical Weathering Weathering […]
Can you convert current to voltage?
Can you convert current to voltage? We usually say that the resistor converts the current IIN into a proportional voltage VOUT or it serves as a simple current-to-voltage converter – a linear circuit with transfer ratio k = VOUT/IIN [V/mA]. A bare resistor can convert current into voltage. How do you convert low current to […]
What is the difference between survival of the fittest and natural selection?
What is the difference between survival of the fittest and natural selection? “Survival of the fittest” is a popular term that refers to the process of natural selection, a mechanism that drives evolutionary change. Natural selection works by giving individuals who are better adapted to a given set of environmental conditions an advantage over those […]
What is the relation between surface tension and surface energy?
What is the relation between surface tension and surface energy? The attractive force of the molecules present at the surface of a liquid towards each other is called the surface tension of that liquid. Surface energy is the equivalent attractive force present between the molecules at the surface of a solid substance. What are the […]
What is the application of third law of thermodynamics?
What is the application of third law of thermodynamics? The third law of thermodynamics states that the entropy of a perfect crystal at a temperature of zero Kelvin (absolute zero) is equal to zero. Entropy, denoted by ‘S’, is a measure of the disorder/randomness in a closed system. All the atoms and molecules in the […]
