Which statement correctly describes magnetic field lines?​

Answer:

The information shows the masses after the compounds are balanced.

2MgO + 2Cl2 → 2MgCl2 + O2

85g + 156g → 188g + 53g

53gas total mass in reactant is equal to product.

A.

53g of O2, because all mass must be conserved.

Answer:

First Law of Motion.

Explanation:

Inertia can be defined as the tendency of an object or a body to continue in its state of motion or remain at rest unless acted upon by an external force.

In physics, Sir Isaac Newton's First Law of Motion is known as Law of Inertia and it states that, an object or a physical body in motion will continue in its state of motion at continuous velocity (the same speed and direction) or, if at rest, will remain at rest unless acted upon by an external force.

The inertia of a physical object such as a truck is greatly dependent or influenced by its mass; the higher the quantity of matter in a truck, the greater will be its tendency to continuously remain at rest.

Hence, it would take much more force and time for a large truck to get going when the traffic light turns green than it does for a small, compact car. This is an example of the first law of motion.

Answer:

[tex] y_{t} = 253.94 m [/tex]

Explanation:

Para resolver este problema debemos contemplar dos tramos.

En el primer tramo, la fuerza aplicada impulsa al cuerpo a subir una altura dada debido a la aceleración que genera esa fuerza.

[tex] \Sigma F = ma [/tex]

[tex] F - P = ma [/tex]

[tex] F - mg = ma [/tex]

En donde:

F: es la fuerza aplicada = 60 N

P: es el peso del cuerpo = mg

m: es la masa del cuerpo = 4 kg

g: es la aceleración debido a la gravedad = 9.81 m/s²

a: es la aceleración

Entonces, la aceleración generada por la fuerza aplicada es:

[tex] a = \frac{F - mg}{m} = \frac{60 N - 4kg*9.81 m/s^{2}}{4 kg} = 5.19 m/s^{2} [/tex]

Ahora, debemos calcular la altura recorrida mientras el cuerpo está acelerado hacia arriba:

[tex] y_{{1}} = y_{0} + v_{0}t + \frac{1}{2}at^{2} [/tex]  

En donde:

[tex] y_{1}[/tex]: es la altura final del tramo 1 =?                                                                          [tex] y_{0}[/tex]: es la altura inicial = 0  

[tex] v_{0}[/tex]: es la velocidad inicial = 0 (parte del reposo)  

t: es el tiempo = 8 s

[tex] y_{1} = 0 + 0 + \frac{1}{2}5.19 m/s^{2}*(8 s)^{2} = 166.08 m [/tex]  

Por lo tanto, mientras el cuerpo está acelerado (durante los 8 s) recorre 166.08 metros.  

Ahora, en el segundo tramo el cuerpo sigue subiendo hasta alcanzar una altura máxima para luego comenzar a descender. Podemos usar la siguiente ecuación para calcular la altura recorrida.  

[tex] v_{f}^{2} = v_{0}^{2} - 2gy_{2} [/tex]  

En donde:    

[tex] v_{f}[/tex]: es la velocidad final = 0 (en la altura máxima)

[tex] v_{0}[/tex]: es la velocidad inicial

Primero debemos encontrar la velocidad inicial en el segundo tramo, que es igual a la velocidad final del primer tramo:

[tex] v_{f} = \sqrt{v_{0} + 2ay_{1}} = \sqrt{0 + 2*5.19 m/s^{2}*166.08 m} = 41.52 m/s [/tex]    

Entonces, la altura recorrida en el segundo tramo es:

[tex] y_{2} = \frac{v_{0}^{2} - v_{f}^{2}}{2g} = \frac{(41.52 m/s)^{2} - 0}{2*9.81 m/s^{2}} = 87.86 m [/tex]

Finalmente, la altura máxima es:

[tex]y_{t} = y_{1} + y_{2} = 166.08 m + 87.86 m = 253.94 m[/tex]

Answer:

the most elliptical orbit is that of COMETA

Explanation:

The eccentricity of a curve in defined as the ratio between lacia to the focus, called c and the value of the axis greater than

         ε = c / a

if we use Pythagoras' theorem

         c = [tex]\sqrt{a^2 - b^2}[/tex]

   substituting

           ε = [tex]\sqrt{1 - (b/a)^2 }[/tex]

if   ε = 0 we have a circumference

In the diagram presented the orbit of the comet is an ellipse a> b

          ε=[tex]\sqrt{1- x} \\ x = (\frac{b}{a} )^2[/tex]

if we expand in series

             ε = 1 - x/2  

             ε=  [tex]1 - \frac{1}{2} \ (\frac{ b}{a} )^2[/tex]

if we neglect the non-linear terms

            ε = 1

Earth's orbit is a small ellipse

             b / a = 149 10⁶ / 151 10⁶

             b / a = 0.98675

             ε = [tex]\sqrt{1- 0.98675^2}[/tex]

               ε = 0.16

a very small ellipse

Planet X, despite not having data, it seems that the sun is in the scepter of the orbit, so b = a

therefore  both the semi-axes of the curve

        e = a / b

Consequently, the most elliptical orbit is that of COMETA.

In a chemical reaction, the atoms and molecules that interact with each other are called reactants. In a chemical reaction, the atoms and molecules produced by the reaction are called products. In a chemical reaction, only the atoms present in the reactants can end up in the products.

Answer:

A. The waves in the water travel faster and at a higher frequency than they travel on land.

Explanation:

The main reason why human ears can hear dolphins' vocalizations while under the water but cannot hear them well on land is because water is denser than air and air particles travel faster in denser particles.

Denser particles also ensures that the frequency of the waves move faster which in turn produces a faster and louder result.

Answer:

La principal diferencia que existe entre la marcha cuando caminamos y cuando corremos, sea con o sin el balón, es la velocidad: al caminar, la velocidad es mucho menor que al correr, y a su vez, correr sin el balón da la posibilidad de correr mucho más rápidamente, debido a que no se requiere una coordinación entre los pasos y el control del balón.

Por otra parte, además de la velocidad, el ritmo cardiaco que se adquiere al caminar es mucho mas bajo que al correr, donde por causa del esfuerzo se aceleran las pulsaciones, aumentando la frecuencia cardiaca y, por lo tanto, la exigencia cardiovascular.

Answer:

Resistance = 252.53 Ohms

Explanation:

Given the following data;

Charge = 0.125 C

Voltage = 5 V

Time = 6.3 seconds

To find the resistance;

First of all, we would determine the current flowing through the battery;

Quantity of charge, Q = current * time

0.125 = current * 6.3

Current = 0.125/6.3

Current = 0.0198 A

Next, we find the resistance;

Resistance = voltage/current

Resistance = 5/0.0198

Resistance = 252.53 Ohms

No one can know the size of the universe, it may in fact be infinitely large.

Explanation:

No one knows the size of the universe because we can't see the entire universe. We can only see the part that is close enough to us that there has been time for the light from it to arrive here. What that means is any part of the universe that it will take more than 14.5 billion years for light to travel to us can not bee seen. It is possible that the universe has no size, that is it is infinite.

We can measure what we call the "visible universe" and that is a sphere around us with a radius of about 50 billion light years, the reason it is more than the age of the universe (14.5 billion years) is because the universe is expanding more rapidly than the speed of light.

The way scientists measure the size of the visible universe is with what is called red shift. Similar to the way a car horn's pitch changes as it passes you due to doppler shift, light too has a shift in is frequency or color depending on if it is moving away or toward you. As light moves away from you it shifts for red and the faster it is moving away the more it shifts. We can estimate the distance objects are away by how much they are red shifted. When we look at the most distance objects we can see they are about 50 million light years away.

The heat absorbed can be calculated using calorimetric equation. The heat absorbed by the copper block of mass 0.500 kg for the temperature difference of 290 to 400 degree Celsius is 2.13 E4 J.

Calorimetry is an analytical tool used to determine the heat energy absorbed or released by a system. The calorimetric equation connecting the mass m, temperature difference ΔT and specific heat capacity c is given by:

q = m c ΔT .

Given,

m = 0.500 kg

c = 387 J/(kg °C )

ΔT = 400 - 290 °C = 110°C.

Then, the heat energy absorbed by the copper block is ;

q = 0.50 kg × 387 J/(kg °C ) × 110°C

  =  2.13 E4 J

Therefore, option E is correct.

Answer:

Explanation:

The term cell is incorrect because, the average voltage of a cell is 3.40 V and as already mentioned in question, the volt of source is 18 V, so cell couldn't be the appropriate word, actually the source is battery.

Now, the source is most likely related to cell because a battery which is the source here, is made up of a "group of cell".
