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.
Answer:
False
Explanation:
The Coriolis force is caused because the Earth rotates at a different linear velocity in the Equator compared to that in the North and South poles. This force makes objects that are not fixed to the ground move in different directions. For example, the hurricanes in the Northern Hemisphere spin counterclockwise and when travelling some distance they move to the right. While in the Southern Hemisphere they spin clockwise and move to the left. The effect of the Corioli force is extremely important on Earth because it determines the water and air currents, for example. Therefore, it is not an insignificant force.
Thought, it is an apparent force because it is not a force directly applied to the air and water, but a force produced by the side effect of the rotation of the Earth.
It is false that a divide separates river systems that travel in the same direction.
Oral rehydration therapy (ORT) is a type of fluid replacement used to prevent and treat dehydration, especially that due to diarrhea. It involves drinking water with modest amounts of sugar and salts, specifically sodium<span> and </span>potassium<span>. Oral rehydration therapy can also be given by a nasogastric tube.
