Why do you weigh by difference?
Weighing by difference is a technique used to calculate the weight of a substance by measuring the weight of the container before and after adding the substance. This method helps to eliminate errors caused by the container's weight, ensuring more accurate measurements of the substance.
How do you calculate the weight of AHU?
To calculate the weight of an Air Handling Unit (AHU), you would need to know the dimensions and materials used in its construction. Multiply the volume of the AHU by the density of the materials to determine its weight. Additionally, you can refer to the manufacturer's specifications for the AHU's weight.
What is the method used to calculate the mass of the sun?
The method used to calculate the mass of the sun is by observing the orbits of planets and other celestial bodies around it, and applying Newton's law of universal gravitation to determine the gravitational force exerted by the sun. This information, along with the distance of the objects from the sun, allows scientists to calculate the mass of the sun.
What method did the scientist demonstrate to calculate the distance of celestial bodies?
The scientist demonstrated the method of parallax to calculate the distance of celestial bodies.
Can the water displacement method be used to calculate the density of an object that floats in the water such as a cork?
Yes, the water displacement method can be used to calculate the density of an object that floats in water. To do this, you would need to measure the volume of the water displaced by the object when it is submerged, and then divide the object's mass by this volume to find its density.
How do you calculate rainfall using the thiessen polygon method?
To calculate rainfall using the Thiessen polygon method, you first need to divide the area into polygons based on rain gauge locations. Then, calculate the area of influence of each rain gauge within its polygon. Finally, you can determine the weight of each rain gauge based on its influence area, which is used to calculate the average rainfall for the entire region.
What are Methods to calculate fat percentage in food?
Soxhlet extraction is the usual method; this doesn't require you to "calculate" anything, except to the extent that "(weight of fat/weight of original sample) * 100" is a calculation.
What is the method to calculate the mass in grams of each sample?
To calculate the mass in grams of each sample, you can use a balance or scale to measure the weight of the sample. The weight measured in grams is equivalent to the mass of the sample.
How do you calculate the percent chloride with the volhard method?
To calculate the percent chloride using the Volhard method, you measure the excess silver nitrate used to titrate the chloride ions in the sample. You then use the volume of excess silver nitrate and the molarity of the silver nitrate solution to calculate the moles of chloride present. Finally, calculate the percent chloride by dividing the moles of chloride by the sample weight and multiplying by 100.
How ostwald and walker method can be used to find out molecular weight?
A strem of dry air is bubbled through the solution & solvent from the loss in weight of solvent & solution the relative loweing of vapour pressure calculated. From relative lowering of vapour pressure molecular weight is calculated. anupama
What is the formula used to calculate the weight of an object if you were given the mass in kilograms?
weight=mass*gravity
Can tapeworms be used for weight loss"?
No, tapeworms should not be used for weight loss as they can cause serious health problems and are not a safe or effective method for losing weight.
What is Meyer's oscillating disc method?
Meyer's oscillating disc method is a technique used to determine the molecular weight of a polymer by measuring the change in weight of a solution containing the polymer as it oscillates at a specific frequency. This method allows for accurate determination of molecular weight and can be used to study the size and structure of macromolecules.
What is the technique used to calculate the volume of an irregular shaped object?
Water Displacement Method?
What apparatus would you use to measure the size of a rock?
A ruler or a measuring tape could be used to measure the dimensions (length, width, height) of a rock, while a scale can determine its weight. For irregularly shaped rocks, a water displacement method can be used to calculate volume, which can then be used to estimate density or mass.
What is the method used to calculate recombination frequency in genetic studies?
The method used to calculate recombination frequency in genetic studies is called the mapping function, which involves analyzing the frequency of recombination events between genes on a chromosome to determine their relative positions.
What is the height and weight scale called that is used to find out your percentage of body fat?
The answer you will most likely get from people is the Body Mass Index, however that does not actually measure body fat. percentages. A better method is to use the U.S. Navy Circumference Method and you can actually calculate your percentage of body fat using this method at http://lowcarbdiets.about.com/library/blbodyfatcalculator.htm. It is best to go to a Dr and use a DEXA Scan or Hydrostatic Weight.
