What is the approximate surface temperature of the 'White Dwarfs'?.

shusha [124]

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)

What is the net force acting on a falling object when it reaches terminal velocity? a force equal to gravity 9.8 m/s2 two times

Leno4ka [110]

Answer:

The net force is zero

Explanation:

When an object is falling, there are two forces acting on it:

- The force of gravity, which is equal to the weight of the object, which pushes the object downwards

- The air resistance, which acts against the motion of the object, so it pulls upward

While the magnitude of the force of gravity is constant, the magnitude of the air resistance increases as the velocity of the falling object increases: at some point of the motion, the air resistance becomes equal in magnitude to the force of gravity. At this point, the net force on the object becomes zero, and according to Newton's second law, the acceleration of the object becomes also zero:

$F=ma$
