Answer:
The answer to the question is
The resultant ground reaction force exerted by the floor on the volleyball player's shoes = 2088.06 N
Explanation:
To solve the queston we list out the variables thus
Mass of volley ball player = 80 kg
Normal force exerted on her shoes by the floor N =2000 N
friction force, f, exerted on her shoes backwards = 600 N
The resultant ground reactive force, R, is given by
R² = N² + f² = 2000² + 600² = 4000000 + 360000 = 4360000
Therefore R = √(4360000) = 2088.06 N
The direction of the force = atan (2000/600) = 73.3 ° clocwise or 106.699 ° counter clockwise
<h3><u>Answer;</u></h3>
Major product; 2-Butanol ;(CH3CH2CH(OH)-CH3)
Minor product; none
<h3><u>Explanation;</u></h3>
- Alkenes undergo an addition reaction with water in the presence of a catalyst to form an alcohol. This type of addition reaction is called hydration.
- For example; in hydration of 2-butene, Water adds across the double bond in a Markovnikov fashion to form 2-butanol
CH3CH2CH=CH2 + H2O (acid catalyst) -----> CH3CH2CH(OH)-CH3
. Its nucleus is unstable.
It was a mixture bc it settled, and compounds dont do that
119.37 g/mol
<h3>Further explanation</h3>
Relative atomic mass (Ar) and relative molecular mass / molar mass (M)
the molar mass/molecular mass of a compound : the sum of the relative atomic mass (Ar) of the constituent atoms
M AxBy = (x.Ar A + y. Ar B)
Atomic weight (Ar) of :
- C : 12.0107 g/mol
- H : 1.00784 g/mol
- Cl : 35.453 g/mol
The molar mass of CHCl₃
