The structure of an individual  molecule will determine which substance  will dissolve.

<u>Option: A</u>

<u>Explanation:</u>

Once a solvent disintegrates, the single atoms, molecules or ions communicate with the solvent, become solved, and are able to diffuse in the solution independently. However, this is not a unidirectional method. When the molecule or ion collides with the surface of an undissolved solute particle, it may bind to the particle in a method called crystallization.

The concentration units or structure are used to define the degree to which a solvent is soluble. A solution can be categorized as hydrophilic (water-loving), implying it has an electrostatic water-looking attraction, or hydrophobic (water-fearing), implying it repels water. A hydrophilic material is polar, and mostly includes groups of O–H or N–H that can shape water bonds.

01. Um carrinho de massa 10 kg é empurrado, horizontalmente, sobre uma superfície plana horizontal, com força constante de 20 N.
Lostsunrise [7]

Responder:

<h2>D. 1.5m / s² </h2>

Explicación:

Usaremos la segunda ley de movimiento de Newton para resolver esta pregunta. De acuerdo con el teorema

es la suma de las fuerzas que actúan sobre el cuerpo a lo largo de la horizontal. Las dos fuerzas son la fuerza móvil (Fm) y la fuerza de fricción (Ff).

Fm = 20 N y Ff = 5 N

\sum Fx = ma_x\\\sum Fx = Fm - Ff\\\sum Fx  = 20N - 5N\\\sum Fx  = 15N

m es la masa del cuerpo = 10 kg

El parámetro requerido es cuál es la aceleración del cuerpo a lo largo de la horizontal.

De la ecuación 1;

a_x = \sum Fx/m\\\\a_x = 15/10\\\\a_x = 1.5m/s^2

Por lo tanto, la aceleración del carro es de 1.5 m / s²

If something is hot, does it contain heat or thermal energy?
zysi [14]
I am absolutely sure that if something is hot,  it contain thermal energy only because <span>if a given body is heated its electrons start to move very fast which means that thermal energy is being produced. Hope everything is clear! Regards!</span>
