If a 20.0ml test tube measures 15.0cm, what is the length in meters?

Answer : The length of the test tube in meter is 0.15 meter

Explanation :

The conversion used for length from centimeter to meter is:

1 cm = 0.01 m

As we are given the length of the test tube is, 15.0 cm. Now we have to determine the length of the test tube in meter.

As, 1 cm of length of the test tube = 0.01 meter

So, 15.0 cm of length of the test tube =

Therefore, the length of the test tube in meter is 0.15 meter

i'm pretty sure its b i might be wrong though!

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
