Answer:
Explanation:
The theory of propagation of error in case of addition and subtraction states that maximum errors are added in absolute terms in both the operation of addition and subtraction . So in this case the subtracted value will be
10.5775 - 10.3005
= .2770 g
errors will be added ie in subtracted value we can find error to the tune of
.0002 + .0002 = .0004 g
So the subtracted value will be written as
.2770 ± .0004
Mercury does not wet glass because of the cohesive forces within the drops are stronger than the adhesive forces between the drops and glass.
If there is no friction, then NO force is needed to keep an object moving. Go back and look at Newton's first law of motion again.
According to parallelogram law of vector addition :
