A) it occurs when earth is between the sun and the moon
Answer: Reflection is the only process in which the wave does not continue moving forward.
Explanation:
Reflection is a process in which the direction of the wave changes when it is exposed to a bounce off barrier. Refraction can be defined as the change in the direction of the wave when the wave passes through one medium to another. Diffraction is a process in which the direction of the wave changes when the wave passes through a particular opening near the barrier.
The melting of polar ice is one effect of the greenhouse effect, or also global warming.
The greenhouse effect, as defined by Merriam-Webster, is "the <span>warming of the surface and lower atmosphere of a planet (as Earth or Venus) that is caused by conversion of solar radiation into heat in a process involving selective transmission of short wave solar radiation by the atmosphere, its absorption by the planet's surface, and reradiation as infrared which is absorbed and partly reradiated back to the surface by atmospheric gases".
In short, "</span>the warming of the surface and lower atmosphere of a planet".
You're walking in one direction, and then the exact opposite of that direction, so you simply have to subtract the two distances.
200-150=50
You're 50 meters west of where you originally started.
You're west because 200 meters west is greater than 150 meters east. If the distance walked east was greater than the distance walked west, you would've been east of your starting position.
Answer: 
Explanation:
Let's begin by explaining that the relation between the Celsius scale and Kelvin scale is:
This means the absolute zero point of the Kelvin scale is 
Keeping this in mind, we have the freezing point and boling point of Methane as:
Freezing point: 
Boiling point: 
According to this, there is a linear relation between the methane scale (
) and the Kelvin scale in the form:
(1)
Where:
is the temperature in Kelvin
is the temperature in degrees Methane
Firstly, we need to find the value of 
and 
with the two given points (
and 
):
When 
and 
:
(2)
When 
and 
:
(3)
Now we have the linear equation:
(4)
Isolating :
(5)
Evaluating for 
:
(6)
Finally:
This means
