This is actually an earth science question. What is the exact elevation of each point?

Ramsar has the highest level of natural radiation in the world.

Hot springs located in the Arkaroola Wilderness Sanctuary in Southern Australia are also credited with higher than normal radiation levels, due to spring water coming in contact with rocks rich in uranium and radon.

The reaction force must be:

75 N up

The option There is a warm layer of air and a cold layer of air closer to the ground. is the correct answer

Comenzemos con unas definiciones.

La posición nos dice la ubicación espacial de un dado objeto.

La velocidad nos dice como cambia la posición a medida que pasa el tiempo.

La aceleración nos dice como cambia la velocidad a medida que pasa el tiempo.

Teniendo esto en cuenta, la respuesta correcta La respuesta correcta es la opción C: "Las posiciones son las mismas"

Para poder entender esto, podemos desarrollar:

Ahora, supongamos un ejemplo.

Sea una persona caminando y un auto yendo en la misma dirección, de tal forma que la persona comienza varios metros delante del auto.

A medida que el auto aumenta su velocidad, eventualmente se encontrara al lado de la persona.

Naturalmente, es fácil darse cuenta de que tanto la velocidad como la aceleración del auto serán mayores que las de la persona, pero la posición (almenos en una dimensión) será la misma.

Podemos interpolar esto a cualquier situación similar, sabemos que para dos objetos que estén al lado del otro la posición será la misma, pero sin más contexto no podemos concluir nada sobre la relación entre las velocidades y las aceleraciones.

Con esto en mente, la respuesta correcta es la opción C: "Las posiciones son las mismas"

Ke²

Explanation:

So,

q2 = e

r = 1m

By coulumb's law,

F = K (q1q2/r²)

F = K (e)(e)/(1)²  

F = Ke²

Answer:

Explanation:

The unit of power is watt .

It's the velocity, but only the magnitude. It can't show the direction of the velocity. So it's better to call it speed.

Answer:

a bus moving with acceleration of 2 meter per second square

Answer:

It means that it's velocity is 2m/s per s

Means it travels 2m in 1st second and 4m in 2nd sec

Answer:

Explanation:

It's not equal and opposite. You're thinking of Newton's 3rd Law. This is not that. This is gravitational attraction between 2 objects. We can figure out mathematically the pull that the earth has on a single person, by using the equation for gravitational force and the universal gravitational constant, G:

[tex]F_g=\frac{Gm_1m_2}{r^2}[/tex] where G is the universal gravitational constant, m1 is the mass of one person, m2 is the mass of the earth, and r-squared is the addition of the radius of the earth plus the radius of you in relation to the surface of the earth.

Let's say a person weighs 150 pounds; in Newtons this is 667 N (rounded from 667.233); his mass then, in terms of the metric system (using 9.8 for gravity), is 68.2 kg. Let's also say that this person is 6 feet tall. 6 feet is the same as 1.83 m (rounded to 3 sig fig's) and the radius from that person's center to the surface of the earth would be about half that height at r = .915 meters. Filling in the formula:

[tex]F_g=\frac{(6.67*10^{-11})(68.2)(5.98*10^{24})}{(6.38*10^6)^2}[/tex] it turns out that the person's radius adds nothing significantly to the radius of the earth, so it doesn't even count mathematically. It's way too small compared to the earth's radius (which is the denominator of that equation). We find that

[tex]F_g=668N[/tex] That's the pull that the earth has on that person which, not coincidentally, is the weight in pounds we said that the person was. Isn't physics amazing!?

Explanation:

Because it breaks the law of moments.

Answer:

14 years

Explanation:

because the light will take four years to reach the earth. And the star is four light years away from the earth.

An imaginary star is four light years from earth. The star has a planet, upon which a large mirror has been installed. The mirror faces earth. A ten year old boy aims his telescope at the mirror,then the boy would be 14 years old when he will see his own reflection.

It can be defined as the distance travelled by the light in one year .it is represented in units of distance such as miles or km.

1 light year is calculated by multiplying the speed of light with the time of one year

1 light year = speed of light × one year time period

1 light year = 3×10⁸ ×(365×24×60×60)

                  =9.461× 10¹⁵ meter

As given in the problem 10 year old boy aims his telescope at the mirror which is 4 light years away then the light has to travel four years to reach the boy ,then the boy would be 14 year old when he would see his own reflection.

Answer:

calar quantities

Answer:

3 m/s

Explanation:

Given,

Total distance = 60 m

Total time = 20 s

We know that,

Average speed = Total distance/Total time

=> Average speed = 60 m/20 s

=> Average speed = 3 m/1 s

=> Average speed = 3 m/s

Average speed=Total distance/Total time
