B
Electrons are found in shells or orbitals that surround the nucleus of an atom
Answer:
300 mM
Explanation:
In order to solve this problem we need to calculate the line of best fit for those experimental values. The absorbance values go in the Y-axis while the concentration goes in the X-axis. We can calculate the linear fit using Microsoft Excel using the LINEST function (alternatively you can write the Y data in one column and X data in another one, then use that data to create a dispersion graph and finally add the line of best fit and its formula).
The <u>formula for the line of best fit for this set of data is</u>:
So now we <u>calculate the value of </u><u><em>x</em></u><u> when </u><u><em>y</em></u><u> is 1.50</u>:
TLDR: The kinetic energy is determined to be zero.
Kinetic energy is energy of motion; when an object is moving (i.e. it has speed or velocity), it has some amount of kinetic energy. The equation itself looks like so:
KE=1/2(m)(v)^2,
where "m" represents the mass of the object and "v" represents the objects speed or velocity. In this example, the ball has stopped, meaning it has no speed/velocity. This means that the final kinetic energy is determined to be zero or none, due to the lack of motion. Mathematically, you can see this by substituting "0" in for "v" (the ball is stopped):
KE=1/2(m)(v)^2
KE=1/2(m)(0)^2
KE=1/2(m)*0
KE=1/2*0
KE=0 J,
or zero kinetic energy.

In physics, a surface wave can occur along any boundary of two different substances. The seismic type of surface wave happens at the boundary between air and rock—the surface of the earth.
Hope this helped you!
God bless ;)
Hi there!
Your correct answer will be 12.2 cm³.
This is how you get there:
1 mL = 1 cm³
With this one conversion factor, you can extrapolate the final answer. When you add the granite to the water, which is filled to 25.0 mL, the water level then moves to 37.2 mL. If you subtract the before volume from the volume after, you will get an answer of 12.2 mL. Then use the conversion factor and, voila! 12.2 cm³
I hope this helps!
