Answer:

La velocidad inicial es 55 [tex]\frac{m}{s}[/tex]y su aceleración es -10 [tex]\frac{m}{s^{2} }[/tex]

Explanation:

Un movimiento es rectilíneo uniformemente variado, cuando la trayectoria del móvil es una línea recta y su velocidad  varia la misma cantidad en cada unidad de tiempo . Dicho de otra manera, este movimiento se caracteriza por una trayectoria que es una línea recta y la velocidad cambia su módulo de manera uniforme: aumenta o disminuye en la misma cantidad por cada unidad de tiempo. Y la aceleración es constante y no nula (diferente de cero).

En este caso la posición del objeto esta dada por la expresión:

[tex]x=x0+v0*t+\frac{1}{2} *a*t^{2}[/tex]

donde x es la posición del cuerpo en un instante dado, x0 la posición en el instante inicial, v0 la velocidad inicial y a la aceleración.

En este caso, por un lado podes considerar:

Reemplazando obtenes:

[tex]90=v0*2+\frac{1}{2} *a*2^{2}[/tex]

[tex]90=v0*2+\frac{1}{2} *a*4[/tex]

[tex]90=v0*2+2*a[/tex]

Y por otro lado tenes:

Reemplazando obtenes:

[tex]120=v0*3+\frac{1}{2} *a*3^{2}[/tex]

[tex]120=v0*3+\frac{1}{2} *a*9[/tex]

[tex]120=v0*3+\frac{9}{2} *a[/tex]

Por lo que tenes el siguiente sistema de ecuaciones:

[tex]\left \{ {{2*v0+2*a=90} \atop {3*v0+\frac{9}{2} *a=120}} \right.[/tex]

Resolviendo por el método de sustitución, que consiste en aislar en una ecuación una de las dos incógnitas para sustituirla en la otra ecuación, obtenes:

Despejando v0 de la primera ecuación:

[tex]v0= \frac{90-2*a}{2}[/tex]

Reemplazando en la segunda ecuación:

[tex]120=\frac{90-2*a}{2} *3+\frac{9}{2} *a[/tex]

Resolviendo:

[tex]120=(90-2*a)*\frac{3}{2} +\frac{9}{2} *a[/tex]

[tex]120=135-3*a +\frac{9}{2} *a[/tex]

[tex]120-135=-3*a +\frac{9}{2} *a[/tex]

[tex]-15=\frac{3}{2} *a[/tex]

[tex]\frac{-15}{\frac{3}{2} } =a[/tex]

-10=a

Reemplazando el valor de a en la expresión despejada anteriormente obtenes:

[tex]v0= \frac{90-2*(-10)}{2}[/tex]

Resolviendo:

[tex]v0= \frac{90+20}{2}[/tex]

[tex]v0= \frac{110}{2}[/tex]

v0=55

Answer:

(1) atomic numbers

Explanation:

The observed regularities in the properties of the elements on the periodic table are periodic functions of their atomic numbers.

The observed regularities in the properties of  the elements are periodic functions of their atomic numbers.

Modern periodic law states that "Properties of elements are a periodic function of their atomic number not by their atomic mass". Modern periodic law was proposed by Henry Moseley in 1913. Physical and chemical properties of elements depend on the number of electrons and their arrangement.

Thus properties of elements are periodic function of their atomic numbers and not atomic masses. If the properties of an element depend on number of proton and neutron then the properties are periodic function of their atomic mass so we can conclude that the observed regularities in the properties of  the elements are periodic functions of their  atomic numbers.

According to the electronic configuration, along with platinum and gold silver is considered to be a noble metal.

Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.

Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.

Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.

Answer:

Q = 4180 J

Explanation:

Given data:

Mass of water = 10.0 g

Initial temperature = 0°C

Final temperature = 100°C

Heat required = ?

Solution:

Specific heat capacity of water is 4.18 j/g.°C.

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

ΔT = 100°C - 0°C

ΔT = 100°C

Q = 10.0 g ×4.18 j/g.°C × 100°C

Q = 4180 J

Explanation:

Many of the properties of organic molecules can be predicted based on the strength of their cohesive molecule-molecule interactions (i.e. how much the molecules want to stick together).  The boiling point (BP) and melting point (MP) of an organic molecule is related to: 1) the molecular weight of the molecule and 2) the "stickiness" of individual molecules for their neighbors.  

   For example, molecules in a liquid are held together by attractive interactions between molecules.  These interactions must be broken (by adding heat) in order to transition into the gas.  The stronger the cohesive interactions, the more heat that is necessary for the liquid-to-gas phase transition.  These same attractive molecule-molecule interactions have to be broken for a solid to liquid phase change.

Examples: (Rank the following molecules in terms of MP and BP.)

Introduction to intermolecular forces:

All of the attractive intermolecular forces are based on the electrostatic attraction of positive charges on one molecule with negative changes.  The stronger the charges, the stronger the attraction between molecules.

How to:

In general, comparisons can only be made between molecules with similar formulas or molecular weights.*  First, identify the functional groups in the molecules being compared.  Each functional group can form different types of intermolecular interactions (see the chart above).  Interactions higher up on the chart form stronger cohesive interactions and will have higher boiling points and melting points.

* Note that larger molecules usually have higher boiling points and melting points.  This is not because of their higher molecular weights but because they usually have greater surface areas with which to form more intermolecular interactions.  This is also why linear molecules tend to have higher MPs and BPs than branched (or more spherically shaped) molecules.  Linear molecules will have more surface area than a more spherically shaped molecule.

All three molecules have approximately the same molecular formula and molecular weights.  Only molecule A contains a strongly polarized or ionic functional group: an aldehyde.  The C=O group in aldehydes generate a strong molecular dipole (partial + and - charges).  Thus, it can form weak attractive dipole-dipole interactions, and A will have the highest boiling point and highest melting point in this series of compounds.

Molecules B and C are alkanes.  They can only form the weakest attractive dispersion interactions between their molecular surfaces.  Due to its long-thin shape, B will have a greater surface area and can form more dispersion interactions than the rounder C.  Therefore, B will have a higher boiling point and melting point than C.

Molecule A is ionic (it has charges).  Therefore, it can form the strongest ion-ion interactions and will have the highest boiling point and melting point.

Molecule B is a carboxylic acid with an acidic proton and basic lone pairs.  Therefore, it can form medium strength hydrogen bonding interactions, and it will have the next highest boiling point and melting point.

Molecule C is a carboxylic ester, which is a polar functional group.  However, it does not have an acidic proton.  Therefore, esters cannot form hydrogen bonds with themselves.  Instead, they can only form weak dipole-dipole interactions and will have the lowest boiling point and melting point in this series of compounds.

Answer:

Explanation:

By thinking about non covalent intermolecular interactions, we can also predict relative melting points. All of the same principles apply: stronger intermolecular interactions result in a higher melting point.

Lead phosphate

Explanation:

Pb3(po4)2 has the compounded name of lead(II) phosphate.

It is a white, crystalline solid that is insoluble in water. Lead(II) phosphate is used in some paints and plastics, and it is also used as a pigment.

The name of the compound is based on the oxidation state of the lead atom. Lead can have two oxidation states, +2 and +4. In Pb3(PO4)2, the lead atom has an oxidation state of +2, so the compound is named lead(II) phosphate.

The phosphate ion has an oxidation state of -3, so there are two phosphate ions in the compound to balance the +6 charge of the three lead atoms.

Answer:

26.35 mmHg

Explanation:

Given data:

Initial pressure = 65.0 mmHg

Initial temperature = 740 K

Final temperature = 300 K

Final pressure = ?

Solution:

According to Gay-Lussac Law,

The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.

Mathematical relationship:

P₁/T₁ = P₂/T₂

Now we will put the values in formula:

65 mmHg / 740 K = P₂/300 K

P₂ = 65 mmHg× 300 K  / 740 K

P₂ = 19500 mmHg. K /740 K

P₂ = 26.35 mmHg
