light waves are first transmitted through the ________ at the front of the eye and enter an opening called the ________ before shining onto the retina.
The transmission of light waves is usually done through cornea of the eyes, then move through another opening which is regarded as pupil before it will get to the retina.
Light waves can be regarded as moving energy which contains microscopic particles known as photons. The vision of the eye can be completed through the light wave passing through the components of the eyes and this process goes thus;Light will move through the (cornea) which is situated at the front area of the eyes into lens. Then both the cornea and the lens give room for the focusing of the light rays to the retina which is situated at the back of the eye .Then through the help of the cells in the retina, the light will be absorbed and then be converted to electrochemical impulses and then transfer it to the brain as well as optic nerve.Therefore, light wave are form of tiny microscopic particles.

In an electron cloud, an electron that is closer from the nucleus has?
Answer:
It should be less energy
Explanation:
The further away from the nucleus, the more it holds, correct? So those closer to the nucleus hold less electrons. So therefore, the ones that are closer must have more energy than the outer electrons.

5. Fill in the blanks with either "More," "Less," or "The Same."
a) If an object has more mass than another object, it will accelerate_less____
b) In order to accelerate an object more, one would need to apply_more____ force.
c) If an equal force is applied to two different objects, the less massive object will accelerate_more___
The answer is less, more and more.
Relationship between mass and accelerationIf an object has more mass than another object, it will accelerate less. In order to accelerate an object more, one would need to apply more force. If an equal force is applied to two different objects, the less mass of an object will accelerate more
The acceleration of an object depends directly on the force acting upon the object, and inversely on the mass of the object.

what is an asteroid called that is smaller than a couple meters wide?
Answer:
Meteoroids
Explanation:
Meteoroids are significantly smaller than asteroids, and range in size from small grains to one-meter-wide objects. Objects smaller than this are classified as micrometeoroids or space dust.
The term by which an asteroid called is smaller than a couple of meters wide is a meteorite.
What are meteorites?A meteorite is a small group of rocks and debris. They are made by the collection of dust and small pebbles. They are smaller than asteroids, and they are formed in outer space, and they fall on earth from outer space, and when they fall into the earth with that great speed, they attain heat.
Meteorites also consist of metals, like nickel, carbides, sulfides, etc. It has been said that in old times the meteorite that contain iron, fall into the earth and the iron from them melted into the core of the earth. They are of different shapes and sizes.
Thus, the term by which an asteroid called is smaller than a couple of meters wide is a meteorite.

El cuerpo de 2kg se suelta de A recorriendo el plano inclinado 60° con la horizontal y de superficie lisa hasta el punto B. Luego recorre el tramo rugoso BC deteniéndose en C. Hallar “L” si se sabe que μ= 0,6.
El valor de L del tramo rugoso B a C con coeficiente de fricción igual a 0,6, recorrido por el cuerpo de 2 kg cuando se suelta del punto A es 5.00 m.
El valor de L se puede calcular a partir de la definición de trabajo:
[tex]W = F_{\mu}*d[/tex] (1)
En donde:
[tex]F_{\mu}[/tex]: es la fuerza aplicada sobre el cuerpo en el tramo de B a C = fuerza de roce = -μN (el signo menos se debe a que está en dirección opuesta a la del movimiento)
μ: es el coeficiente de roce = 0,6
N: es la normal = mg
m: es la masa del cuerpo = 2 kg
g: es la aceleración debida a la gravedad = 9,81 m/s²
d: es la distancia = L =?
Por otra parte, el trabajo también se define como la diferencia de energía mecánica entre los puntos B y C.
[tex] W = E_{C} - E_{B} [/tex] (2)
Al igualar la ecuación (1) con la (2) tenemos:
[tex]E_{C} - E_{B} = F_{\mu}*d[/tex] (3)
En el punto C, la energía es cero (0) dado que el cuerpo se detiene y en el punto B la energía que tiene el objeto es la cinética:
[tex] E_{B} = \frac{1}{2}mv_{B}^{2} [/tex]
En donde:
[tex]v_{B}[/tex]: es la velocidad del cuerpo en el punto B
La velocidad del cuerpo en el punto B se puede calcular mediante conservación de energía entre los puntos A y B:
[tex] E_{A} = E_{B} [/tex]
En el punto A, el cuerpo tiene energía potencial gravitacional, por lo tanto:
[tex] mgh = \frac{1}{2}mv_{B}^{2} [/tex] (4)
En donde:
h: es la altura = 3 m
Entonces, la velocidad en el punto B es (eq 4):
[tex] v_{B} = \sqrt{\frac{2mgh}{m}} = \sqrt{2*9,81 m/s^{2}*3 m} = 7,67 m/s [/tex]
Ahora, la ecuación (3) queda como sigue:
[tex] 0 - \frac{1}{2}mv_{B}^{2} = -\mu N*L [/tex]
[tex] \frac{1}{2}2 kg*(7.67 m/s)^{2} = 0,6*2 kg*9,81 m/s^{2}*L [/tex]
Resolviendo para L, tenemos:
[tex] L = \frac{\frac{1}{2}2 kg*(7.67 m/s)^{2}}{0,6*2 kg*9,81 m/s^{2}} = 5.00 m [/tex]
Por lo tanto, el valor de L es 5.00 m.

Question 5 (1 point) true or false: Balanced forces acting on an object result in constant velocity True False
Answer:
false
Explanation:
By Newton's first law (An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force), neither speed nor direction change. Our force is balanced.
Balance forces could happen when the object is at rest but not all the time. A balance force is when a object is being push in opposite directions, which would cause the object to stay still or move at a constant speed. Which would mean that balance force could take place when a object is moving or when a object is at rest.

Henry ran a 100 m race. Use the graph to answer the following:
a. How long did it take for Henry to run 100 m?
b. What is Henry's average speed over the race?
Using the graph, which describes how Henry ran the 100m race;
a) It takes Henry 20seconds to run 100m
b) Henry's average speed over the race is; 5m/s.
According to the linear graph which describes the distance ran by Henry during the 100m race as a function of time.
a) Since the distance from start ran by Henry is plotted on the vertical axis, and the time is plotted on the horizontal axis;
To determine how long it took Henry to run 100m; The point corresponding to 100m is traced downward from the line of the graph and we find out that;
It takes Henry 20seconds to run 100m
b) Henry's average speed over the race is simply;
The slope of the distance-time graph.
Therefore,
Average speed = (100-0)/(20-0)Average speed = 100/20Average speed = 5m/s.Therefore, Henry's average speed over the race is; 5m/s.

How did Lavoisier's study of combustion prove that fire was not an element?
Answer:
In June 1783, Lavoisier reacted oxygen with inflammable air, obtaining "water in a very pure state." He correctly concluded that water was not an element.
Explanation:
As the fire left behind ashes of a substance it indicated that it is not an element as element cannot be decomposed in to simpler substances.
What is an element?It is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.
Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.
The number of protons in the nucleus is the defining property of an element and is related to the atomic number.All atoms with same atomic number are atoms of same element.

why should a building have better thermal insulation placed in its ceiling than in its walls
Answer:
In a building, heat rises. By putting the insulation in the ceiling heat will rise and get trapped at the top and fill up the entire room. The purpose of insulation is to minimize the transmission of heat within the walls, floors, and ceilings. By minimizing the transmission of heat, you not only keep the room warm but you also lower your electricity and heat bill.
