The equation of the last question which is 3CO2 + 4H2O has a total of 21 atoms with the following number of atoms of each element:
C= 3
C= 3H = 8
C= 3H = 8O = 10.
<h3>What is a chemical formula?</h3>
A chemical formula is defined as the expression that is used to show the chemical symbol of and element in a chemical compound and the number of atoms of those elements.
There are three main type of formula that include the following:
- Empirical formula : This is the type of chemical formula that shows the simplest whole-number ratio of atoms in a compound.
- Molecular formula: This is the type of chemical formula that shows the number of each type of atom in a molecule.
- Structural formula: This is the type of chemical formula that shows how this atoms of each element are bonded together.
The given chemical formula above is a molecular formula that contains the following number of atoms per elements:
C= 3
C= 3H = 8
C= 3H = 8O = 10. Which is a total of 21 ( green)

We need first to use the formula F=m(a+g), m iis the total mass, a is the acceleration, g is gravity pulling the blocks. So the procedure will be
<span>m=2kg(both blocks)+500g(both ropes) → m=2.5kg </span>
<span>a=3.00m/s^2 </span>
<span>g=9.8m/s^2 </span>
<span>F=m(a+g) → F=2.5kg (3.00m/s^2 + 9.8m/s^2) → F=2.5kg (12.8m/s^2) → F=32 N
To calculate the tension at the top of rope 1 you need to use the formula </span>T=m(a+g) so it will be <span>T=m(a+g) → T=1.5kg(12.8m/s^2) → T=19.2N
</span>We can now calculate the tension at the bottom of rope 1 using the formula: <span>T=m(a+g) → T=1.25kg(12.8m/s^2) → T=16N
</span>Now to find the tension at the top of rope 2 we do it like this:
<span>T=m(a+g) → T=.25kg(12.8m/s^2) → T=3.2</span>
Answer:
The centripetal force is 0.54 N.
Explanation:
mass, m = 0.56 kg
radius, r = 0.72 m
angular speed, w = 1.155 rad/s
The centripetal force is given by
