There are several ways to model a compound. one type of model is shown. 4 c's are connected in a line by 3 black lines. the c on the left has 3 h's attached to it each by a black line. the next c has 1 h attached by a black line and 1 o attached by 2 black lines. the next c has 2 h's attached to it by 1 black line each. the last c has 2 h's attached to it by 1 black line each and 1 o attached by a single black line. that o has an h attached to it by 1 black line. what is the chemical formula for the molecule represented by the model? cho c4h9o2 c4h8o c3h8o2

Answer : The chemical formula for the molecule is

Explanation :

Molecular formula : It is the chemical formula which depicts the actual number of atoms of each element present in the compound.  

Structural formula : It is a formula in which the lines are used between the bonded atoms and the atoms are also shown in the structural formula.

In the structural formula, the lines are used between the atoms.

As per given information of compound we conclude that, there are 4 carbon atoms, 9 hydrogen atoms and 2 oxygen atoms.

Thus, the chemical formula for the given molecule will be,

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
