If an object suspended by a scale shows a weight of 3 N in air, and 2 N when submerged in water, the buoyant force on the submerged object is . View Available Hint(s) If an object suspended by a scale shows a weight of 3 N in air, and 2 N when submerged in water, the buoyant force on the submerged object is . 2 N 1 N 3 N more than 3 N

Explanation:

Given that,

Object weight in air Wa = 3N

Object weight in water Ww = 2N

Buoyant force?

From Archimedes' principle: the buoyant force is equal to the weight of the fluid displaced by the object.

So initial the weight of the object was 3N in air, when place in water the weight reduces to 2N, then, from Archimedes principle, the fluid displaced is 1N.

Then, the buoyant force is 1N

Mathematically

Buoyant force + Weight in substance = Weight in air

Fb + Ww = Wa

Fb = Wa — Ww

Fb = 3—2

Fb = 1 N

Buoyant force is equal to 1N

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.
