vivado [14]
The correct answer to this question is this one:

By definition, if a molecule is composed of two hydrogen atoms and one oxygen atom, that molecule is a water.<span> In fact, the structure of water is written as H20, which signifies that two hydrogen (H) atoms and one oxygen (O) atom make up the molecule.</span>

A block with mass M is placed on an inclined plane with slope angle q and is connected to a second hanging block with mass m by
tensa zangetsu [6.8K]

Answer:

The mass of the block m is:

m=M(sin(\theta)+\mu_{s}cos(\theta))

Explanation:

Let's analyze the block by parts

For the block M

T-W_{x}-f_{f}=0 (1)

Where:

  • T is the tension
  • W(x) is the component of the weight in the x-direction
  • F(f) is the friction force

T-Mgsin(\theta)-\mu_{s}N=0  

T-Mgsin(\theta)-\mu_{s}Mgcos(\theta)=0  

For the block m

T-W=0

T=mg (2)

Now, let's combines equation (1) and (2):

mg-Mgsin(\theta)-\mu_{s}Mgcos(\theta)=0  

Finally, let's solve it for block m.

mg-Mg(sin(\theta)+\mu_{s}cos(\theta))=0

m=M(sin(\theta)+\mu_{s}cos(\theta))

I hope it helps you!

Select all that apply. Which of the following are characteristics of acids? contain hydroxide ion or produce it in a solution ta
julia-pushkina [17]
These are the characteristics that apply:

 - In a solution taste sour: which is consequence of the H+ concentration.

- Corrode metals: the H+ ion reacts with the metal producing a salt and water

-Produce hydronium ion in solution: as per the Bronsted - Lowry definition an acid is a substance that donates a proton, H+. This proton will react with H2O to form H3O+ (hydronium), as per this scheme: 

HA + H2O --> A(-) + H3O(+)

Qué estudios se realizan en la actualidad para utilizar la electricidad de una manera más eficiente?
Margarita [4]

Answer:

Se realizan estudios en tres áreas: a) Procesos de transformación de la energía, b) Almacenamiento de la energía, c) Gestión inteligente entre consumo y generación.

Explanation:

Actualmente, se están realizando estudios en principalmente en tres áreas cruciales: a) Procesos de transformación de la energía, b) Almacenamiento de la energía, c) Gestión inteligente entre consumo y generación.

a) Se están desarrollando nuevos materiales que permiten mayor eficiencia entre la energía recibida y la energía eléctrica, además de una mayor durabilidad frente a las condiciones ambientales. Esto implica el mejoramiento del desempeño de las tecnologías basadas en las energías renovables y limpias, acortando su brecha con las energías no renovables.

b) Se están desarrollando nuevos materiales que garanticen una mayor densidad energética y mayor durabilidad, significando baterías más compactas, con mayor capacidad y más competitivas económicamente.

c) Se están desarrollando estrategias de control inteligente a tiempo que permite sincronizar el consumo y la generación, además de posibilitar el flujo bidireccional de la energía a través de una red inteligente (smart grid) e integrar mejor las fuentes renovables dentro de la matriz energética.
