You call to a friend from a boat floating in the ocean. Which best describes the changes in the speed of the sound waves as they

Alina [70]

The correct answer is: The speed of sound is faster in the water than in the air.

The speed of sound is different between those two mediums because they have different densities. Since, water is denser than air, more energy is required to generate a wave but once it stars, it travels faster than it would do in air. Sound waves’ travel can be presented by particles that transmit the energy one to another as they bump. The sound speed is lower in the air (than in water) because particles are far apart, so they travel further before they collide.

Where is the moon when you are in a location experiencing a low tide?

Citrus2011 [14]

Answer:

C

Explanation:

The gravity of the sun and moon pull on the water of the oceans of the earth hence causing a bulge of these waters at the point on earth where the moon is above. The region where the moon is above, and the opposite side on the earth, will therefore experience high tides while the places at right angles (on the surface of the earth in relation to the moon position) will experience low tides.

How do trees act as carbon sinks?

Romashka [77]

The best answer is D.

A carbon sink is anything that absorbs more carbon than it produces or releases.

The main carbon sinks found in nature are plants, the ocean and soil. Plants such as trees capture carbon dioxide from the atmosphere and use it in photosynthesis. Part of this carbon is transferred to soil as the trees and other plants die and decompose.

Due to the effectiveness of trees and other plants as carbon sinks, the Kyoto protocol proposed that emission reduction can be achieved through absorption of carbon dioxide by these plants.
