An oxygen molecule consists of two oxygen atoms, (O2), whose total mass is 5.3 × 10–26 kg and whose moment of inertia about an a

Katena32 [7]

Answer : The distance between the two atoms is $1.2\times 10^{-10}m$

Explanation :

The The formula used for moment of inertia for one atom is:

$I=(\frac{m}{2})r^2$

The formula used for moment of inertia for two atom is:

$I=2(\frac{m}{2})r^2$

where,

I = moment inertia = $1.9\times 10^{-46}kg.m^2$

r = distance of atom from axis of rotation

m = mass of atom = $5.3\times 10^{-26}kg$

Now put all the given values in the above formula, we get:

$I=2(\frac{m}{2})r^2$

$1.9\times 10^{-46}kg.m^2=2(\frac{5.3\times 10^{-26}kg}{2})r^2$

$r=6.0\times 10^{-11}m$

Now we have to calculate the distance between the two atoms.

Formula used :

$d=2r$

where,

d = distance between the two atoms

$d=2\times 6.0\times 10^{-11}m=1.2\times 10^{-10}m$

Therefore, the distance between the two atoms is $1.2\times 10^{-10}m$

What % of all the atoms in the universe are hydrogen

irga5000 [103]

Answer:

Over ninety percent of all the atoms in the Universe are hydrogen atoms.

Explanation:

Over ninety percent of all the atoms in the Universe are hydrogen atoms. By mass, hydrogen makes up about 75% of all matter in the Universe. Hydrogen atoms are also the smallest and lightest of all the atoms with only one electron and one proton in a common single hydrogen atom (called protium).

Answer:

To plot a graph, you put the independent variable on the y-axis and the dependent on the x-axis. This might sound really hard, but it's not.

A dependent variable is something that is changed by other factors. For example, in this question, the temperature is dependent on the time. You can't change time by temperature, it's impossible. But you CAN change temperature by the more time that goes by. This makes Time independent and Temperature Independent.

You write the graph so that Time (1-10) goes up the side (the y-axis), starting from the bottom left (this point is called the origin). Then you write the Temperature on the bottom, from left to right. The numbers you are given have to have the same amount of points (the little squares you see) in between them, and you have to be able to fit all of the numbers on the graph.

The last step is to plot the points on the graph so they match up. If the time is 1, then you go to where the time says one and move over to the right to where it is the correct temperature. That is where you put your point. You keep doing this until you have all the points plotted and you can connect the dots.
