Rowena and helga are both performing an experiment with nickel metal. Rowena has a 5 gram sample and determines the density to b

e 8.9g/cm3. If helga has a nickel sample that is twice as large and has a mass of 10 grams what would be the density of helgas sample?

Answer:

The density of helgas sample is 17.8 g/cm³.

Explanation:

Given that,

Mass of sample of Rowena = 5 gram

Density = 8.9 g/cm³

Mass of sample of helga = 10 gram

We need to calculate the volume of sample

Using formula of volume

V=\dfrac{m}{\rho}

Where, m = mass

\rho = density

Put the value into the formula

V=\dfrac{5}{8.9}

V=0.56\ cm^3

We need to calculate the density of helgas sample

Using formula of density

\rho=\dfrac{m}{V}

Where, m = mass

V = volume

Put the value into the formula

\rho=\dfrac{10}{0.56}

\rho=17.8\ g/cm^3

Hence, The density of helgas sample is 17.8 g/cm³.

What does continental drift and sea floor spreading have in common
Llana [10]

In the early 1900s, a scientist named Alfred Wegener noticed how the continents seem to fit together and developed the Theory of Continental Drift. Continental drift is the theory that continents can drift apart from one other and have done so in the past. Wegner's theory also explained why fossils of the same plant and animal species are found on both sides of the Atlantic Ocean. In addition similar types of rock and evidence of the same ancient climatic conditions are found on several continents.

Wegner hypothesized that all the separate continents of today were once joined in a single landmass that he called Pangaea.
