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.
To answer this item, we let x be the number that is not unknown in this item such that the situation in this problem can be expressed as follows,
x - 9.3 = 68.91
Adding 9.3 to both sides of the equation,
x - 9.3 + 9.3 = 68.91 + 9.3
Simplifying,
x = 78.21
The answer to this item is 78.21, this I think is the first choice except that it is mistakenly written as 7.21 only.
Answer:
The question can be best explained in the light of the world hydrological cycle.
Explanation:
- This is a process of the hydrological cycle were the waterfalls in the form of rains and later on gets absorbed or evaporates from the ground or natural vegetation. This falling water may also get collected as lakes and other water bodies.
- When it rains in the neighbour the water the falls on the ground is in filtered through the pore of the soil and percolates deep down to form aquifers and groundwater table.
- This water body acts as a reservoir and in the end, meets with the water of the ocean and sea through the subsurface flow.
