<span>Oxygen-15 is an isotope of oxygen, frequently used in positron emission tomography, or PET imaging. It has 8 protons, 7 neutrons, and 8 electrons. The total atomic mass is 15.0030654 amu. It has a half-life of 122.24 seconds.</span>
Answer:
10 kilowatts or 10,000 kw
Explanation:
Power = Force × Velocity
Given that:
Velocity of car is 50 m/s
The force is 200N
The power would be:
P = 200 × 50
P = 10,000 W
Notice that it only reaches watts because of the unit of the velocity is m/s. Standard unit to make Kw is km.
Since:
1 kw = 1000 w
10 kw = 10000 w
Credits to the person below me for correction.
Added together = 159.7 grams for one mole of Fe2O3<span>. That is moles of hematite, but the question is about iron. We can see there are </span>two<span> iron atoms for every hematite molecule. So the number (moles) of iron atoms is twice the moles of the hematite molecules.
so depending on how much you initially have will determine the answer</span>
Answer:
a. Kenya's growth seems to be a large population influx, an increase in the pre-reproductive stage.
b. There is a decrease in the younger generation, meaning that the reproductive part of the population is more than the pre-reproductive part. Which means less of an incline in population.
c. You can see the differences within the countries, that the growth rate in Kenya is extremely high, the United States more moderate, while Germany is somewhat even throughout. Germany is not growing much in comparison to Kenya.
Answer:
The correct answer is - both act only between non-atomic particles.
Explanation:
The decreasing order of their relative strength is - the strong force, electromagnetism, weak force, gravity.
so, A would be here = gravity
B would be = weak force
C would be = strong force
The weak and strong forces both are fundamental forces that act on sub-atomic particles only such as quarks.
