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.

Answer:

The theory of relativity usually encompasses two interrelated theories by Albert Einstein: special relativity and general relativity, proposed and published in 1905 and 1915, respectively. Special relativity applies to all physical phenomena in the absence of gravity. General relativity explains the law of gravitation and its relation to other forces of nature.It applies to the cosmological and astrophysical realm, including astronomy.

The theory transformed theoretical physics and astronomy during the 20th century, superseding a 200-year-old theory of mechanics created primarily by Isaac Newton. It introduced concepts including spacetime as a unified entity of space and time, relativity of simultaneity, kinematic and gravitational time dilation, and length contraction. In the field of physics, relativity improved the science of elementary particles and their fundamental interactions, along with ushering in the nuclear age. With relativity, cosmology and astrophysics predicted extraordinary astronomical phenomena such as neutron stars, black holes, and gravitational waves

Answer:

Explanation:

When the object strikes the ground, it then becomes in uniform motion and when an object is in uniform motion, the velocity is 0

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"

Answer:

I think deep-water wave is not a wave

Explanation:

but it will be better if u wait for the second answer as I am not sure

Shallow water wave is not a type of wave. Thus, the correct option is C.

A wave is a disturbance in a medium which carries energy without a net movement of particles in the medium. A wave may take the form of elastic deformation, it is a variation of pressure, electric or the magnetic intensity, electric potential, or the temperature of the medium.

Shallow water waves take place in the shallow water, this means that the waves which occur at depths that is shallower than the wavelength of the wave divided by 20. This would mean that a wave with a wavelength of about 60 meters is a shallow water wave at depth range of less than 60 divided by 20, or 3 meters.

Therefore, the correct option is C.

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

Explanation:

Convert the time to seconds = 0.6 × 60 × 60

= 2160seconds

Velocity = distance ÷ time

Velocity = 500 ÷ 2160

Velocity = 0.23meters per seconds(m/s)

Acceleration = Velocity ÷ time

Acceleration = 0.23 ÷ 2160

Acceleration = 0.000106meters per seconds ²(m/s²)

We know
