The answer is water because since water is used to make the rainbow so they are simillar hope this was helpful!!
Answer:
Using wood also helps keep carbon out of the atmosphere, helping to mitigate climate change.
Deforestation.
Explanation:
Trees store carbon dioxide as they grow. After harvest, wood products continue to store much of this carbon. These benefits continue when wood is reclaimed to manufacture other products.
Extraction of wood within the supply areas clearly affects the forest and the environment. Some of these impacts can be seen in the study areas. The rainfall is increasingly irregular, biodiversity has been lost. Communities have experienced flooding and drought, which adversely affects the most important sector in the country's economy, that of agriculture. The local populations are concerned about these impacts, which affect not only the environment but the whole social economy.
Answer:
Because as the waves propagates, the particles of the medium (molecules of water) vibrates perpendicularly (upward and downward) about their mean position and not in the direction of the waves.
Explanation:
A wave is a phenomena which causes a disturbance in a medium without any permanent deformation to the medium. Examples are; transverse wave and longitudinal wave. Waves transfer energy from one point in the medium to another.
The waves generated by water are transverse waves. Which are waves in which the vibrations of the particles of the medium is perpendicular to the direction of propagation of the waves.
Thus as the waves propagates, the molecules of water vibrates up and down and not along the direction of propagation of the waves. So that the floating objects do not get pushed in the direction of the waves every time.
Answer: (a) Smaller charge is 
and larger charge is 
.
(b) Smaller charge is 
and larger charge is 
.
Explanation:
(a) When both the spheres have same charge then force is repulsive in nature as like charges tend to repel each other.
Therefore, total charge on the two non-conducting spheres will be calculated as follows.
= 
Therefore, force between the two spheres will be calculated as follows.
F = 
12 N = 
or, 
This means that smaller charge is and larger charge is .
(b) When force is attractive in nature then it means both the charges are of opposite sign.
Hence, total charge on the non-conducting sphere is as follows.
Now, force between the two spheres is calculated as follows.
F =
12 N =
Hence, smaller charge is and larger charge is .
Answer:
Explanation:
Acceleration is the rate of change of an object with respect to time. It is the change in velocity over the time.
The car starts at 10 meters per second and increases to 20 meters per second in 2.5 seconds.
= 20 m/s 
= 10 m/s - t= 2.5 s
Substitute the values into the formula.
Solve the numerator.
Divide.
The acceleration of the car is <u>4 meters per second squared.</u>
