The specific gravity of a substance is given by G = DS/DW, where DS is the density of the substance in kg/m3 and DW is the density of water, which is known to be 1000 kg/m3. The density of a particular substance is measured to be DS = 500±5 kg/m3. Estimate the specific gravity, and find the uncertainty in the estimate

Explanation:

The specific gravity is given by,

Now, in order to calculate the uncertainty (relative error) in G, we must first take log (base e) on both sides of the equation,

Differentiating the above equation,

The second term is zero because it is known that and hence a constant.

Putting the appropriate values, we get,

Therefore, uncertainty in G =

gravititional force is a force that is acting around you, it is non-contactable and it is a force that pulls you to the core of the earth.

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
