Answer:
![2.4*10^{7}cm^{3}](https://tex.z-dn.net/?f=2.4%2A10%5E%7B7%7Dcm%5E%7B3%7D)
Explanation:
First you should calculate the volume of a big sphere,so:
![V_{big}=\frac{4}{3}\pi r^{3}](https://tex.z-dn.net/?f=V_%7Bbig%7D%3D%5Cfrac%7B4%7D%7B3%7D%5Cpi%20r%5E%7B3%7D)
![V_{big}=\frac{4}{3}\pi (181cm)^{3}](https://tex.z-dn.net/?f=V_%7Bbig%7D%3D%5Cfrac%7B4%7D%7B3%7D%5Cpi%20%28181cm%29%5E%7B3%7D)
![V_{big}=2.4*10^{7}cm^{3}](https://tex.z-dn.net/?f=V_%7Bbig%7D%3D2.4%2A10%5E%7B7%7Dcm%5E%7B3%7D)
Then you calculate the volume of a small spehre, so:
![V_{small}=\frac{4}{3}\pi r^{3}](https://tex.z-dn.net/?f=V_%7Bsmall%7D%3D%5Cfrac%7B4%7D%7B3%7D%5Cpi%20r%5E%7B3%7D)
![V_{small}=\frac{4}{3}\pi (5.01cm)^{3}](https://tex.z-dn.net/?f=V_%7Bsmall%7D%3D%5Cfrac%7B4%7D%7B3%7D%5Cpi%20%285.01cm%29%5E%7B3%7D)
![V_{small}=5.3*10^{2}cm^{3}](https://tex.z-dn.net/?f=V_%7Bsmall%7D%3D5.3%2A10%5E%7B2%7Dcm%5E%7B3%7D)
Finally you subtract the two quantities:
![V_{big}-V_{small}=2.4*10^{7}cm^{3}-5.3*10^{2}cm^{3}](https://tex.z-dn.net/?f=V_%7Bbig%7D-V_%7Bsmall%7D%3D2.4%2A10%5E%7B7%7Dcm%5E%7B3%7D-5.3%2A10%5E%7B2%7Dcm%5E%7B3%7D)
![V_{big}-V_{small}=2.4*10^{7}cm^{3}](https://tex.z-dn.net/?f=V_%7Bbig%7D-V_%7Bsmall%7D%3D2.4%2A10%5E%7B7%7Dcm%5E%7B3%7D)
Answer:
Time (months) is the independent variable
Growth (measured) is the dependent variable.
Explanation:
Let y = growth
Let x = time
The result will yield a relation of the form
y = y(x), or y is a function of x.
x, the time can be controlled. The experimenter can decide how many months to conduct the experiment. It is the independent variable.
y, the growth is a response to the amount of time allowed for growth. It depends on x, therefore y is the dependent variable.
Answer: There are many possibilities for atomic orbits.
Explanation: In chemistry orbits, or orbitals, are the areas that electrons move around the nucleus of an atom. Think like the solar system.
There are three levels of orbitals (p,d, and f).
That should get you started. Use p, d and d described in your book to find out how many orbitals an atom has.
