It is D, the distance between each object squared. We get this from solving for the force of gravity, which is
F = G((m1*m2)/(r^2)).
Here, you can see that the masses of the two objects are divided by their total distance apart from each other (r) squared.
Answer:
I) You walk barefoot on the hot street and it burns your toes.
II) When you get into a car with hot black leather in the middle of the summer and your skin starts to get burned.
Explanation:
In conduction mode of heat transfer we know that the energy is transferred from one system to other system due to direct contact of two bodies
Here due to this direct contact the energy is transferred via a given solid or liquid medium
In this type of heat transfer medium particles will remain in its own position only the energy is transferred.
So here we can say the correct answer will be
I) You walk barefoot on the hot street and it burns your toes.
II) When you get into a car with hot black leather in the middle of the summer and your skin starts to get burned.
a=v/t
a=38/10
a=-3.8 m/s^2
You put the negative in front of 3.8 because it decelerated.
Hope it helps and is correct :)
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)
