Answer:
Tiene que patear el balón cerca del nivel del suelo para conseguir el gol.
Explicación:
Leo Messi necesita patear el balón no en el aire, en el nivel del suelo para poder meter el gol para el equipo. Delante del fútbol hay muchos jugadores del equipo contrario dispuestos a detener el tiro libre de Leo Messi. Cuando Leo Messi patea el balón en el aire, los jugadores también saltan en el aire para detener el tiro libre que atraviesa la cabeza y para conseguir el gol Leo Messi tiene que evitar patear el balón en el aire y patear el balón cerca del nivel del suelo. que puede atravesar a los jugadores oponentes cuando lo saltan para detener el balón a través de sus cabezas para que el balón pase por debajo de sus pies y llegue a la portería.

A. to power a battery
B. to light a lamp
C. as a voltage divider
D. convert chemical energy to thermal energy
Answer:
C
Explanation:
a series circuit would be an odd choice to power a battery or light a lamp when a direct would be much more efficient, and it's not converting types of energy, so C is the best possible answer

Write 3 major differences between a shadow and a image?
Explanation:
Image Shadow
2. We are able to see images when light refraction enters our eyes.
In the case of shadow no light enters our eyes.
3. Image contains colour, structure etc. of the object.
Shadow does not give any information about the object as it is colourless

A 31 kg child is traveling at 4 m/s while sledding down a hill. What is the child's kinetic energy at the bottom of the hill?
Answer:
K.E = 248 J
Explanation:
Since the child is travelling at a given velocity. The kinetic energy of the child down the hill can be given by the following formula:
[tex]K.E = \frac{1}{2}mv^2\\[/tex]
where,
m = mass of the child = 31 kg
v = velocity of the child = 4 m/s
Therefore,
[tex]K.E = \frac{1}{2}(31\ kg)(4\ m/s)^2\\[/tex]
K.E = 248 J

Answer:
#tried my bestt
do mark me as brainlist
Biomolecules are made by living organisms and they are made because they are functional. Biomolecules, or at least most of them, do not exist outside of living organisms because they are too complex to be created by chance chemical collisions. The odds of a single average sized protein to form by chance has been calculated at 1 out 10 to the 77th power. Biomolecules REQUIRE intelligent agency to form them.
The four main purposes of biomolecules are:
1. Structure (some proteins)
2. Energy storage and release (carbohydrates)
3. Protective layers (lipids)
4. Information storage and communication (DNA, RNA, endocrines of numerous various types and manipulated molecules, such as fatty acids)

Objects A and B are brought close to each other. Object A will soon become positively charged. Identify the charge that must transfer for this
situation to occur.
+
A
B
Answer:
Explanation:
For A to become positively charged, a + charge must transfer from B to A.
The charge that must transfer for object A to become positively charged is the negative charge in object A.
What is charging by conduction?Charging by conduction occurs when a charged object causes the flow of electron when it comes in contact with an uncharged object.
An object can either be negatively or positively charged. An object is said to be positively charged when it contains more protons than electron.
Therefore, for object A to be positively charged, the charge that must transfer for object A to become positively charged is the negative charge.

An image is a copy of an object formed by ____
light.
The answer is: Reflected
Explanation:
An image is a copy of an object that is formed by reflected (or refracted) light. Regular reflection occurs when light reflects off a very smooth surface and forms a clear image. Diffuse reflection occurs when light reflects off a rough surface and forms a blurry image or no image at all.
Un texto de opinión sobre la situación actual del rol de la mujer, el trabajo y las situaciones de violencia en el contexto de Pandemia. Cambió la situación de las mujeres?
Explanation:
Los derechos de las mujeres fueron conquistados a través de importantes luchas llevadas a cabo por mujeres, como el movimiento feminista que tuvo lugar a fines del siglo XIX, cuyo principal reclamo fue el derecho al voto de las mujeres.
Con el tiempo, las mujeres ganaron más derechos y una mayor participación en el mercado laboral y en puestos importantes de la sociedad. Pero aún queda mucho por cambiar, ya que las estadísticas aún muestran que hay pocas mujeres en posiciones de poder en relación a los hombres, y el salario de una mujer que ocupa el mismo puesto que un hombre es siempre menor.
Dado que la sociedad se concibió a través de parámetros sexistas, lo que continúa en la actualidad, es claro que en la pandemia específicamente que generó crisis económicas en todo el mundo, se vio a una gran cantidad de mujeres perder sus empleos, además del expresivo número de casos de violencia doméstica que se agravaron en el período de aislamiento social.
Así que estos hechos solo demuestran que la lucha por la igualdad de género y los derechos de las mujeres aún están en sus inicios, a pesar de muchos logros que las mujeres aún deben luchar por lo básico, que es el apoyo social y político además de una legislación más estricta que castiga con más rigor a las agresoras. Las mujeres deben estar protegidas por la ley y las instituciones y los medios de comunicación deben abordar más el tema y promover el feminismo como una lucha por la igualdad.
3/8 of light initial intensity is absorbed in the breaker with length of 2cm filled with 9% solution. Find the length of the beaker should be used to get transmittance 1/3 for the same solution
Answer:
Assume I1 = Io * T1 transmission proportional to thickness
I2 = Io * T2 I is intensity of light absorbed (3/8 absorbed)
I1 / I2 = T1 / T2
T2 = T1 * (I2 / I1) = 2 * (2/3 / 3/8) = 2 * 16/9 = 32/9 thickness for 2/3 absorbed
The length of the beaker when the transmittance is changed to one-third is 13.78 cm.
The given parameters;
length of the beaker when 3/8 of the light intensity is absorbed = 2 cm = 0.02 mTo find:
the length of the beaker when there is 1/3 transmittanceThe length of the beaker is calculated by applying Beer-Lambert law;
[tex]\frac{I}{I_o} = e^{-cl}[/tex]
[tex]\frac{I_1}{I_0} = e^{-cl_1} = \frac{3}{8} \ ----(1)\\\\\frac{I_2}{I_0} = e^{-cl_2}= \frac{1}{3} \ ---- (2)[/tex]
divide equation (1) by equation (2);
[tex]\frac{e^{-cl_1}}{e^{-cl_2}} = \frac{3}{8} \times \frac{3}{1} \\\\ (c \ is \ constant \ for \ both) \\\\e^{-l_1 + l_2} = \frac{9}{8} \\\\l_2 - l_1 = ln(\frac{9}{8} )\\\\l_2 - 0.02 = 0.1178\\\\l_2 = 0.1178 + 0.02\\\\l_2 = 0.1378 \ m\\\\l_2 = 13.78 \ cm[/tex]
Thus, the length of the beaker when the transmittance is changed to one-third is 13.78 cm.

4. Predicting What would have happened, in terms of thermal energy transfer, if the water temperature had originally been10.0°C? Explain your reasoning.
Context:Background InformationThe quantity of energy transferred by heat from a body depends on anumber of physical properties of the body and its surroundings. For a given substance, the rate at which thermal energy is transferred by conduction depends on temperature difference, cross-sectional area,and a thermal conductivity constant that is unique to the substance.By choosing one of these properties as a manipulated variable and making the other properties controlled variables, the effect of the manipulated variable on thermal conduction can be determined experimentally.In this investigation, you will study the rates of cooling of three containers of water of equal volume but different surface area.
