Question

1.A graduated cylinder with a least count of = 0.5 ml is used in a density

Answer 1

We have that

 

From the question we are told

• A graduated cylinder with a least count of $\pm 0.5 ml$
• The initial water level, before inserting the irregular
• shaped solid.
• Is 30.0 ml. After inserting the solid,
• The water level is 34.5 ml.

Generally the equation for the new quantity. is mathematically given as

X=Initial level - Final Level $\pm$ (initial and final error)

Therefore

$X (34.5-30.0) \pm(0.5+0.5)\\\\X= 4.5\pm 1.0$

Therefore

The Probable error is

$x=\pm 1.0ml$
