Taking into account the Newton's second law, the correct answer is option A. F = 9.68 N right

In first place, acceleration in a body occurs when a force acts on a body.

Newton's second law states that a force will change the speed of an object because the speed and/or direction will change. These changes in velocity are called acceleration.

So, Newton's second law defines the relationship between force and acceleration mathematically. This law says that the acceleration of an object is directly proportional to the sum of all the forces acting on it and inversely proportional to the mass of the object

Mathematically, Newton's second law is expressed as:

F= m×a

where:

  • F = Force [N]
  • m = Mass [kg]
  • a = Acceleration [m/s²]

In this case, you know:

  • F= ?
  • m= 2.2 kg
  • a= 4.4 m/s²

Replacing in Newton's second law:

F= 2.2 kg× 4.4 m/s²

Solving:

<u><em>F= 9.68 N</em></u>

Finally, As the bowl of fruit accelerates to the right, the correct answer is option A. F = 9.68 N right

What's wrong with this thermochemical equation?
mafiozo [28]

This thermochemical equation needs to be balanced. Hence, option B is correct.

<h3>What is a balanced chemical equation?</h3>

A balanced equation contains the same number of each type of atom on both the left and right sides of the reaction arrow.

The balanced thermochemical equation is:

H_2(g) + 2NaCl (s) + 3O_2 (g) → 2HCl (l) + 2Na (s) + 2O_3 (g)

Hence, option B is correct.

The atomic number of fluorine is 9. How many electrons does an ion of fluorine have if it is represented by the symbol shown bel
Irina-Kira [14]
  • See charge on ion is -1 .

Hence it has taken 1 electron

Now first look at EC of Fluorine(F)

\\ \bull\sf\dashrightarrow 1s^22s^22p^5

  • Now one electron added .hence no of electrons is 10now

Look at the EC

\\ \bull\sf\dashrightarrow 1s^22s^22p^6

Or

\\ \bull\sf\dashrightarrow [He]

Option C is correct.
