please show the work :(What is the estimated force applied to the box if the acceleration is .40 m/s2?

force (N) acceleration (m/s2)
10 .20

? .40​

Answers

Answer:

20N

Explanation:

Given parameters:

        Force(N)     Acceleration(m/s²)  

            10                   0.2

           ?                      0.4

Unknown:

The force applied when the acceleration is 0.4m/s²

Solution:

From newton's second law of motion;

 Force = mass x acceleration

 Since we are using the same box, let us find the mass of the box;

      Force  = mass x acceleration

         10 = mass x 0.2

            mass = [tex]\frac{10}{0.2}[/tex]  = 50kg

Now,

 The force in the second instance will be;

      Force  = 50 x 0.4  = 20N

how to write the ionic formula for the K1+, MnO41- pair of ions

Answers

Answer:

Ionic formula: KMnO4

Explanation:

Pottasium permanganate (KMnO4) is an ionic compound that contains a combination of pottasium cations (K+) and permanganate anion (MnO4-). The pair of ions that make up the ionic compound cancel out each other to make it neutral.

K+ (aq) + MnO4- (aq) → KMnO4 (aq)

MnO4- contains 1 atom of manganese with a (+7) charge and four atoms of oxygen with a (-2) charge each. This forms a +7 for Mn and -8 for O4, hence, a net total of -1.

¿Por qué un trozo de sal común es frágil y se puede romper fácilmente cuando se le somete a una fuerza y no ocurre lo mismo con un trozo de metal que se deforma antes de romperse?

Answers

Answer:

Explanation:

La sal común es un compuesto iónico, es decir que sus átomos (Na y Cl) están unidos entre sí por fuerzas electrostáticas, y el metal está unido entre sí por uniones metálicas. La naturaleza de estas uniones es diferente y en base a las fuerzas de atracción que hay entre los átomos en compuestos con este tipo de uniones, la propiedades físicas generales serán diferentes.

En el caso de los metales, los átomos metálicos están colocados unos sobre otros de forma ordenada, pero no fijamente retenida, y los electrones de valencia están delocalizados a través de todo el cristal metálico. Por esta razón, cuando se le aplica una fuerza a un metal, estos átomos pueden deslizarse unos sobre otros. Ésta es la propiedad que le da a los metales su maleabilidad.

En el caso de los compuestos iónicos, los aniones y cationes que lo componen están ordenados en el cristal de una forma más rígida y por eso cuando se les aplica una fuerza éstos compuestos se rompen mucho más fácil, ya que no pueden deformarse.

Help pleasee I need help to write the formulas i’m so lost

Answers

Answer:

NH4

Explanation:

A piece of silver is heated and added to a styrofoam cup calorimeter containing 26.0 mL (the density of water is 1 g/mL) of water at 19 oC. The water reaches a maximum temperature of 44 oC after the metal was added. If the specific heat of the silver is 0.240 J/g oC and it started at 93.8 oC

Answers

Answer:

m(Ag) = 227.5g

Explanation:

...what is the mass of the piece of silver?

The heat given for the piece of silver is the same heat that is absorbed for the water, that is:

m(Ag)×C(Ag)×ΔT(Ag) = m(Water)×C(Water)×ΔT(Water)

m is mass of water in solution: 26.0mL = 26g of water

And m(Ag) is the mass of Ag, our incognite.

C is specific heat (0.240J/g°C for Ag), and 4.184J/g°C for water

ΔT is change in temperature (93.8°C - 44°C = 49.8°C) for Ag ad (44°C - 19°C = 25°C)

Replacing:

m(Ag)×C(Ag)×ΔT(Ag) = m(Water)×C(Water)×ΔT(Water)

m(Ag)×0.240J/g°C×49.8°C = 26g×4.184J/g°C×25°C

m(Ag)* 11.952J/g = 2719.6J

m(Ag) = 227.5g

A. K, Mg, N, O
B. C, Al, P, Cl
C. Li, Be, H, He
D. Na, Ne, He, H​

Answers

Answer is b, trust. :)

The elements that have least protons to those having the most protons in the atoms are:

B. C, Al, P, Cl

Protons in an atom:

There is an equal number of protons and electrons in an atom. So when moving across a period in a periodic table the number of electrons increases which also shows the increases in a number of protons. So as the atomic number increases, the number of protons and electrons also increases.

Thus, the order of elements having least to greatest protons are:

C, Al, P, Cl

C has 6 atomic number, Aluminium has 13 atomic number , Phosphorus has 14 atomic number and atomic number of chlorine is 17.

Thus, option B is correct.

The chemical equation represents a reaction between ammonia and oxygen to form nitrogen monoxide and water. 4 N H 3 ( g ) + 5 O 2 ( g ) → 4 NO ( g ) + 6 H 2 O ( g ) What is the limiting reagent when a 4.50 g sample of ammonia is mixed with 15.80 g of oxygen?

Answers

The limiting reagent : NH₃

Further explanation

A method that can be used to find limiting reactants is to divide the number of moles of known substances by their respective coefficients, and small or exhausted reactants become a limiting reactant

Reaction

4NH₃(g)+5O₂(g)⇒4NO(g)+6H₂O(g)

mol NH₃ :

[tex]\tt \dfrac{4.5}{17}=0.265[/tex]

mol O₂ :

[tex]\tt \dfrac{15.8}{32}=0.494[/tex]

mol ratio

NH₃ :

[tex]\tt \dfrac{0.265}{4}=0.06625[/tex]

O₂ :

[tex]\tt \dfrac{0.494}{5}=0.0988[/tex]

Limiting reactants : NH₃ (smaller ratio)

The limiting reagent when a 4.50 g sample of ammonia is mixed with 15.80 g of oxygen is NH₃

Calculation of limiting reagent:

The limiting reactant refers to the reactant that gets consumed first in a chemical reaction and thus it limits how much product can be created or developed. A method that can be used to determine limiting reactants that to divide the number of moles by their respective coefficients.

So,

For mol NH₃ :

[tex]= 4.5\div 17[/tex]

= 0.494

For mol O₂ :

[tex]= 15.8 \div 32[/tex]

= 0.494

For mol ratio

NH₃ :

[tex]= 0.265 \div 4[/tex]

= 0.06625

O₂ :

[tex]= 0.494 \div 5[/tex]

= 0.0988

Based on the above calculations we can say that it is NH₃

How are elliptical galaxies different from spiral galaxies?
a. They contain older stars and less gas and dust.
b. They contain younger stars and more gas and dust.
c. They are bigger than spiral galaxies.
d. They are smaller than spiral galaxies.

Answers

Answer:

A. They contain older stars and less gas and dust.

Explanation:

There are three types of galaxies:

elliptical galaxiesspiral galaxieslenticular galaxies

Elliptical galaxies are galaxies shaped like an ellipse, while spiral galaxies consist of a flat, rotating disk that contains stars, gas, and dust, and a central concentration of stars called the bulge.

The difference between elliptical and spiral galaxies is in the amount of gas and dust they contain. Spiral galaxies contain large amounts of gas and dust, which means that new stars are born very often. This makes them brighter than relatively dim elliptical galaxies, which contain less gas and dust. This is why fewer new and brighter stars are born in elliptical galaxies, leaving them with older, dimmer stars.

(2) If da Vinci did have exotropia, in which an eye turns outward, he would not have been the only artist in history with that condition.(3) Christopher Tyler, a visual neuroscientist at City University of London, noticed a pattern in da Vincis portraits and in works depicting the great artist. (4) While few self-portraits of da Vinci exist, Tyler argues that many of da Vincis portraits reflect his appearance. (5) As the great artist himself said, the soul guides the painters arm and makes him reproduce himself, since it appears to the soul that this is the best way to represent a human being.(6) To test his theory that da Vinci had exotropia, Tyler studied the eye alignments of the subjects of six pieces of art that purportedly depict the Renaissance artist himself, including da Vincis Vitruvian Man and Salvator Mundi and Andrea del Verrocchios sculpture David. (7) The results confirmed Tylers suspicions: da Vinci likely had exotropia, with one eye turning out at -10.3 degrees.(8) Tylers findings, which he published in JAMA Ophthalmology, created a stir in both the art and science communities. (9) Only about 1 percent of the population has exotropia, yet previous studies have suggested that other famous artistslike Rembrandt, Picasso, and Degashad it as well, which indicates that the eye condition was more common in centuries past than it is now. (10) Tyler believes that da Vincis condition was intermittentthat is, his eye drifted out of alignment when he was relaxed, but when he focused, it would realign. (11) If Tyler is right and da Vinci could control his exotropia, then the artist could switch from 2-D to 3-D vision, enhancing his ability to accurately capture three-dimensional figures on a two-dimensional canvas.The writer is working on a revision of the passage and has written the following thesis statement for it.Based on the evidence from Tylers studies, it is clear that this condition was the primary reason for da Vincis success.Which of the following is most likely the main claim that the writer is planning to make in the new version of the passage?The only way for an artist to be successful is to have exotropia.ADa Vinci was more successful as an artist than others who also had exotropia.BStudying just a few works of art can provide compelling information about an artists physical conditions.CThe only way to fully understand an artists work is to study the artists physical conditions.DDa Vinci was a great artist because he had exotropia.EIs it E?
