Force acting on the body when the body is at rest the net formals is given
Answer:
Your answer is Gravity,
The Earth's gravity pulls things at a rate of 9.8m/s² (varying depending upon one's distance). according to Newton, "all mass in the universe exerts some gravitational force". you are pulling on Sagitarios A* (the black hole at the center of the milky way galaxy) right now, and it is also pulling on you.

<u>Answer:</u> The number of carbon and oxygen atoms in the given amount of carbon dioxide is 
and 
respectively
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
Given mass of carbon dioxide gas = 3.45 g
Molar mass of carbon dioxide gas = 44 g/mol
Putting values in above equation, we get:
1 mole of carbon dioxide gas contains 1 mole of carbon and 2 moles of oxygen atoms.
According to mole concept:
1 mole of a compound contains 
number of molecules
So, 0.0784 moles of carbon dioxide gas will contain 
number of carbon atoms and 
number of oxygen atoms
Hence, the number of carbon and oxygen atoms in the given amount of carbon dioxide is and respectively
The answer to this question would be: 2.36 mol
To answer this question, you need to know the molecular weight of copper. Molecular weight determines how much the weight of 1 mol of a molecule has. Copper molecular weight about 63.5g/mol. Then, the amount of mol in 150g copper should be: 150g / (63.5g/mol)= 2.36 mol
