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,

Therefore, Henry's average speed over the race is; 5m/s.

Explanation:

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.

If 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.

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.

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.

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.

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.

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.

Answer:

The box gains 3200 J of kinect energy.

Explanation:

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:

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.

Explanation:

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.
