Carbon-13 has an atomic mass of 13.
Atomic mass is the sum of protons and neutrons.
There are 6 protons, so there are 13 - 6 = 7 neutrons.

Answer is 7 neutrons (and 6 electrons)

Trees are part of the biosphere. They need water to survive. They take in water from the soil through their roots and release wa

dolphi86 [110]

Answer:

Explanation:

The hydrosphere represents the total amount of water on earth. Soil water is part of the hydrosphere.

The lithosphere represents the varieties of rocks present on the planet, including their weathered part which is the soil.

The atmosphere represents the different gas layers surrounding the earth.

The biosphere represents the portion of the earth that supports life.

When soil water moves into the tree through the roots of the tree, the hydrosphere, the lithosphere and the biosphere are interacting all together. When the some of the water taken in is released to the atmosphere as vapor through evapotranspiration, it represents an interaction with the atmosphere.

Titanium is a metal used to make golf clubs. A rectangular bar of this metal measuring 1.96 cm x 2.19 cm x 2.63 cm was found to

masha68 [24]

$4.012\frac{gr}{cm^3}$

Explanation

the density of an object is given by:

$\text{Density(d)}=\frac{mass(m)}{\text{volume(v)}}$

Step 1

find the volume of the bar

a)find the volume of the rectangular bar.

the volume of a rectangular prism is given by:

$\text{Volume}=\text{ length}\cdot widht\cdot depth$

replace

$\begin{gathered} \text{Volume}=(\text{ 2.63}\cdot2.19\cdot1.96)(cm^3) \\ \text{Volume}=11.289012(cm^3) \end{gathered}$

Step 2

now,

Let

$\begin{gathered} \text{Volume}=11.289012(cm^3) \\ \text{mass}=\text{ 45.3 gr} \end{gathered}$

replace in the formula

$\begin{gathered} \text{Density(d)}=\frac{mass(m)}{\text{volume(v)}} \\ d=\frac{45.3\text{ gr}}{11.289012(cm^3)} \\ d=4.012\frac{gr}{cm^3} \end{gathered}$

therefore, the answer is

$4.012\frac{gr}{cm^3}$

I hope this helps you

On a graph of position vs. time, what do the x-values represent? What do the y-values represent?

jasenka [17]

The x-values equal time (usually in seconds according to physics position vs. time graphs) and the y-values equal distance (usually in meters according to physics position vs. time graphs). I hope the answer helps. Thank you for posting your question here.
