A balance works by using a rigid beam that is horizontally suspended across a support axis that holds two identical trays or surfaces. One tray holds an object with an unknown mass, while another tray holds premade objects of known mass. The mass of the unknown object is determined by ...
Mass is defined as the amount of matter in an object while weight is defined as the force exerted by an object. SI unit of mass is kilograms while SI unit of weight is Newtons. Object weighing 1 kg mass will have 9.8 N weight.
A balance beam scale is a scale that works by using sliding weights on graduated beams. It's normally used to measure things like...
A budget is a microeconomic concept that reveals the trade-off made when one good is exchanged for another. In terms of the bottom line—or the end result of this trade-off—asurplus budgetmeans profits are anticipated, abalanced budgetmeans revenues are expected to equal expenses, and adefici...
In every chemical reaction, when reactants react to give products, the net charge in the reaction remains conserved, this property is seen in the charge balance equation of the reaction. The mass is also conserved in the equation, which is seen in the mass ...

air, oil, water, etc. 2. what is a homogeneous mixture? sugar mixed with water is the most common example of a homogeneous mixture. homogeneous mixtures can be defined as the mixtures which possess the same properties and combination throughout their mass. examples of homogeneous mixtures ...
Balances measure the mass, or gravitational mass, of an object while scales measure the weight, or the compression force of constraint. However, many balances are now used like scales to measure the weight of an object. A balance is recognized as a scale with a higher resolution. Resolution ...
And the cute little puppy is lighter.We have different weighing machines or scales to determine the weights of different things. The weight of an object can be measured using different types of weighing scales. A scale or balance is a device used to measure weight or mass. These are also ...
