The flow of energy starts with the sun. Like plants can make their energy through the sunlight from the sun. And they create food from the process of photosynthesis.
Answer:
d 2,4,3
Explanation:
2 Al2O3 ----> 4 Al + 3 O2
An element has no charge so its protons must be balanced with its electrons
so if X has 82 protons then it must have 82 electrons so that the atoms sum of charges adds up to 0
hope that helps
Answer:
Image result for What evidence in Side View lets you know that upwelling is happening in these locations?
Winds blowing across the ocean surface often push water away from an area. When this occurs, water rises up from beneath the surface to replace the diverging surface water. This process is known as upwelling.
Explanation:
Answer:
- <u><em>The bag with no sunscreen held the most vibrant beads.</em></u>
Explanation:
<em>SPF</em> is the Sun Protection Factor. It indicates how long a person can stay out in the sun before his skin start burning. It is a factor that is multiplied by 15 minutes. SPF 30 means 30 times 15 = 450 minutes. SPF 70 means 70 times 15 = 1,050 minutes.
Thus, the bag covered in <em>SPF 30</em> <em>sunscreen</em> will raise its temperature faster than the bag covered in <em>SPF 70 </em>sunscreen. And the bag with <em>no sunscreen </em>will raise its temperature faster than the other two.
The higher the temperature the more vibrant the particles that consititute the substances, thus, you conclude that the bag that held the most vibrant beads is the bag with no sunscreen.
Remember that the temperature is a measure of the kinetic energy:. The relation is: the higher the temperature the higher the kinetic energy.
Therefore, the more the particles vibrate, the higher the kinetic energy and the higher the temperature.
