Solar energy is the correct answer. Two of the processes that make up the water cycle need solar energy and these include:
1. Transpiration- as plants absorb water from the soil, the soil, the water moves through the stem to the leaves . Once the water reaches the leaves , some of it evaporates from the leaves, adding to the amount of water vapor in the air. This process of evaporation from the leaves is known as transpiration and requires warmth of the sun (heat energy) to make temperatures jut right for it to take place
2. Evaporation- water that has returned to earth through precipitation and found in rivers, lakes, sea, and ponds when heated by the sun's thermal (solar) heat energy evaporates and as water vapor rises again into the atmosphere.
Correct answer: a) True.
In fact, the soil at the poles consists mainly of snow. Snow has an albedo of 90%: albedo is the fraction of light (and so, of energy) that is reflected back to the space. This means that at the poles, about 90% of the light is reflected back to the space, while only 10% is absorbed.
Answer and Explanation:
The light that comes from the sun is called white light. Actually white light is a mixture of lights of different colors. When we look at the rainbow we can see the colors that make up the white light. This phenomenon, known as dispersion, occurs when a ray of composite light is refracted (refraction) in some medium, and its constituent colors are separated.
I attached you I picture where you can see this process
Basically, when the light passes through a glass prism, the different wavelengths that make up the beam of light travel inside it at different speeds and curl differently when entering and leaving resulting in a beam deviated from the initial direction and with its separate components.
Answer:
The answer is B
Explanation:
5/2=2.5
2.5x2=5
Hope this helps ik its kinda confusing lol
Answer:42.4m/s^2
Explanation:
Velocity(v)=6m/s
Radius(r)=0.85 meter
Centripetal acceleration=(v x v) ➗ r
Centripetal acceleration=(6 x 6) ➗ 0.85
Centripetal acceleration=36 ➗ 0.85
Centripetal acceleration=42.4
