The correct answer is option 2. A 0.8 M aqueous solution of NaCl has a higher boiling point and a lower freezing point than a 0.1 M aqueous solution of NaCl. This is explained by the colligative properties of solutions. For the two properties mentioned, the equation for the calculation of the depression and the elevation is expressed as: ΔT = -Km and <span>ΔT = Km, respectively. As we can see, concentration and the change in the property has a direct relationship.</span>

Read the information about the three atoms given in the table. Which of them are isotopes of each other?
skelet666 [1.2K]
<span>The option A is correct answer. The isotopes are X and Y. The isotopes are those which have same atomic number but different mass number. Since atomic number has same number of protons or electrons. Thus, isotopes have same number of protons or electrons. Therefore, X and Y are isotopes.</span>

The bowl of fruit has a mass of 2.2 kg.
AURORKA [14]

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
