The Gulf Stream is a current that carries water north along the eastern coast of the United States. Which of the following descr

ozzi

The correct answer is - C. Warm water is carried to cooler parts of the ocean.

The Gulf Stream is warm ocean current. It is an ocean current that originates from the Caribbean region, where it is constantly warm throughout the year. Because of that, the water is warm as well, and since the warm water is less dense, it moves on the surface. The movement is toward the higher latitudes, where this current, as a surface movement of the water, is bringing warmer water to the cooler areas, such as the eastern coast of the United States. Not only that warm water is brought to these areas, but the Gulf Stream also brings in warm and moist air masses with it, making the climate much more mild, and increasing the amount of precipitation.

A certain material has a normal freezing point of 10ºC and a normal boiling point of 70ºC. What state is the material in at room

ahrayia [7]

Explanation:

A freezing point is defined as the point in which a liquid state of a substance changes into solid state.

Whereas boiling point is defined as the point at which liquid state of substance starts to convert into vapor state.

So, a substance is freezing at $10^{o}C$ and boils at $70^{o}C$ then it means at room temperature, that is, around $25^{o}C$ the substance is present in liquid state.

This is because between the freezing and boiling point a substance will always exist in liquid state.

Thus, we can conclude that state of the material at room temperature is liquid.

Explains why anyone in the classroom can hear that loud teacher...

Explanation:

Let us first differentiate reflection, refraction, and diffraction.

Reflection occurs when the waves bounce off the medium or the boundary that is in the way of the wave. Some part of the wave would bounce off, and the others would go through the medium through a process called transmission.

When light for example hits a smooth surface at a certain angle, the light would bounce off, creating an equal going the other way.

Best example of this behavior of light would be the mirror.

Refraction on the other hand, bends the waves as they go through one medium to another medium, or change their direction. The amount or degree of the bend would depend on the medium they go through. If the mediums are different, it would substantially change the wave's path. The reason for this is because the medium changes the speed of the waves that go through them, depending on the material they are made up of.

A classic example of this would be the straw in a glass of water.

Diffraction occurs when the waves go through an opening of the medium or barrier. If the opening is smaller than the wave that passes through it, it would spread out wider, coming out of the opening, but if it is bigger, then the spread would decrease.

In x-ray crystallography, they use this by letting x-rays pass through the spaces in between the crystals.
