awh i need to kno this too DX
mass is measured with a balance comparing an unknown mass with an object of known mass. weight is not measeured with the same tools as mass.
A variable whose value is not known, or not yet known.
known, familiar
Yes, it is (unknown reasons, unknown consequences). The word known is the past participle of the verb 'to know' and can act as an adjective. Unknown is the antonym (opposite) and means unidentifiable or mysterious.
As part of planning, you might draw a diagram that helps you visualize a relationship between the known and the unknown. You might need to use a table or graph to identify data or to identify a relationship between a known quantity and the unknown. Hope that helps (:
The metal bar above the beams, known as the front beam support, is held when carrying the triple beam balance from place to place. It is important to grip this bar securely to prevent any damage to the balance.
Yes.
Density can be used to determine the identity of a substance by comparing the density of the unknown substance to the known densities of different substances. Each substance has a characteristic density, so if the density of the unknown substance matches that of a known substance, it can help identify the unknown substance.
A1. Mass is determined by using a beam balance, and comparing the unknown mass with known masses.
That is not known because the cause of RA is unknown.
you have to u measure it with a triple beam balance
That would be a balance or a balance scale. It compares the weight of an unknown object to the weight of known masses to determine the object's weight.
A double beam balance is used to measure the mass of an object by comparing it to known masses on the balance pans. The two beams allow for a more precise measurement by fine-tuning the comparison between the unknown mass and the known masses.
It is just for human convenience. If the person who uses the physical balance is left handed then placing the unknown mass in the right pan will be the most convenient for him. So easyness to place the weights on the pan is considered. Hence the usual procedure.
On a triple beam balance, you should move the largest dial (usually the one with the highest gram value) first to roughly align with the known weight of the object you are measuring. Then, adjust the two smaller dials for finer measurements until the balance is level and stable.
The lowest rider on the triple beam balance should always be moved first. This rider is typically the most sensitive and helps to provide the most accurate measurements.
A balance or a scale is typically used to measure the mass of an object in a laboratory setting. These instruments work by comparing the unknown mass to a known mass to determine the weight.
