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,
Answer:
The answer to your question is: c = 353 mi/h; Ф = 7.3°
Explanation:
You can see the picture below
To solve this problem, just imagine a right rectangle which the legs is 350 mi/h and 45 mi/h and we are going to find the hypotenuse.
c² = a² + b²
c² = 350² + 45²
c² = 122500 + 2025
c² = 124525
c = 352.9 ≈ 353 mi/h
tanФ = 45/ 350
tan Ф = 0.12
Ф = 7.3°
Answer:
412.1 N
Explanation:
First of all let's calculate the total speed of the ball as it is released, which is equal to the speed of the ball + the speed of the bowler:
Now let's convert it into m/s. We know that
So
And now we can calculate the centripetal force, which is given by:
where
m = 0.16 kg is the mass of the ball
v = 40.6 m/s is the speed of the ball
r = 0.64 m is the radius of the circular path (equal to the length of the bowler's arm)
Substituting:
