you push a block of 50kg with a force of 400 N over a distance of 8m. How much kinetic energy does the box gain?
Answer:
The box gains 3200 J of kinect energy.
Explanation:
What is kinect energy?Kinect energy is the energy of an object has because of its motion. Almost anything that has mass and it's in motion has kinect energy. Examples:
wind;throwing a footbal;driving a car;lauching a rocket;etc.What is the work energy theorem?Also known as the principle of work and kinect energy, it states that the work done by all forces acting upon an object equals the change of its kinect energy.
For example, if you pull a box, then you're exerting a force on it and it moves forward. Since the box has mass and it's in motion, you have changed its kinect energy.
Solution:
Write the data down:
[tex]\bullet \quad \mathsf{m=50\,kg}\\\\\bullet \quad \mathsf{F=400\,N}\\\\\bullet \quad \mathsf{d=8\,m}[/tex]
Apply work energy theorem:
[tex]\mathsf{W}= \Delta\mathsf{K}[/tex]
The amount work done equals the change of kinect energy:
[tex]\mathsf{W}=\mathsf{K-K_o}[/tex]
Since the block is at rest at the beginning, so it has zero initial kinect energy:
[tex]\mathsf{W}=\mathsf{K-0}\\\\\\\mathsf{W}=\mathsf{K}[/tex]
Now, apply the formula for work to the left hand side of the equation:
[tex]\mathsf{F\cdot d}=\mathsf{K}\\\\\\\mathsf{400\cdot 8}=\mathsf{K}\\\\\\\therefore \boxed{\mathsf{K=3200\,J}}[/tex]
Conclusion: the box has gained 3200 J of kinect energy.
Happy studying!

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.
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.

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.

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.
