Answer:
The process of combining the smaller nuclei to make larger one is called fusion.
Fusion occurs on the sun.
Explanation:
Fusion:
It is the process in which smaller nuclei combine to form the larger nuclei.
Fusion process also occur in the sun.
It is known as proton-proton fusion. In this proton-proton fusion, the atoms of hydrogen fused together and form helium-4. This is accomplished through several steps hydrogen atoms combine to form deuterium.
This deuterium atom fused with proton and form helium- 3.
Gamma rays are also produced in this reaction.
This helium-3 combine with another helium-3 and form helium-4 atom and two protons.
Sublimation occurs more readily when definite weather circumstances are present such as low relative humidity and dry winds. Sublimation also occurs more at higher altitudes where the air pressure is less than at lower altitudes and energy such as strong sunlight is also needed. Sublimation happens a lot in the south face of Mt. Everest which have low temperatures, strong winds, intense sunlight, very low air pressure and the recipe for sublimation to occur.
Answer:
2 curies
Explanation:
This is actually pretty easy to explain.
The Radium-226 which is an isotope of the radium, have an activity of curie. This is basically used in radioactivity of certain elements.
As in both cases we have Radium -226 and we are only varying the mass of the Radium, then, we can just do a rule of 3 to calculate this:
1 g Ra-226 --------> 1 Curie
2 g Ra-226 --------> X Curie
Solving for X:
X = 2 g * 1 Curie / 1 g
<h2>
X = 2 Curies.</h2>
You can also see this by taking 2 grams of Ra per separate. On one side you have 1 g of Ra-226 and on the other side, you have another 1 g of Ra-226. Both have 1 Cury of activity. If you put both on the same side, you will have 1 Cury of 1 isotope plus 1 cury of the other isotope, final result? 2 curies.
Hope this helps
Answer:
the mean is 6 but you don't have that as an option.
Explanation:
the mean is the average.
to find the mean you have to add all of your data first
3 + 2 + 2 + 12 + 6 + 5 + 14 + 4 = 48
then you have to divide your answer by how many numbers there are in total.
48 / 8 = 6
the mean is 6.
