You should put this in science not geography
Answer:
Parallax would be most effective in measuring distances to stars which are close to the Earth.
Explanation:
In the experiment,
- The parallax shift would decrease as the pencil would move further away from the scientist's eye, so option 1 would be invalid.
- the size of the pencil remains constant, so option 2 would be invalid.
- the parallax shift can be observed when the pencil has objects in the background to provide relation, that is to say, the shift of the pencil when seen relative to background objects; therefore, if we assume that the pencil is a star nearby to the Earth, and the background objects are stars that are further away, then the shift of, and thus, distance to the nearby star can be easily observed.
The correct answers are:
- At Earth's pole;
- At high latitudes;
- At high altitudes;
The glaciers are a frozen ice mass that is slowly moving from a higher toward a lower region. For them to exist, specific conditions are required, the most important of which is that the climate is very cold throughout the whole year. The places that provide suitable conditions for the existence of glaciers are the Antarctica (where most of them are located), the island of Greenland, as well as the very high mountains that have cold weather throughout the whole year, especially at their highest parts, like the Alps and the Himalayas.
Answer:
Explanation:
Given
Parallel to: 
Passes through (-9,-4)
Required
Determine the line equation
First, we calculate the slope (m) of the said line
Make y the subject
Divide through by 3
An equation has the general form:
Where
So:
Because the required line is parallel to , then they have the same slope of
Next, is to calculate the line equation using:
Where
This gives:
Open bracket
