The attractive force that keeps the nucleus together is called nucleus force.
<span>The nucleus becomes increasingly more stable upon the addition of nucleons up to iron-56.
</span>So, as the size of the nucleus increase more iron 56 are needed.
Iron-56<span> (</span><span>56Fe</span><span>) is the most common isotope of </span><span>iron.</span>
Answer: The answer is D. KNO3
Explanation:
The graph shows that the KN03 going straight up from the temperature sign so you reversed that so that it will make it to 90°C to 30°C
Answer: The force needed is 140.22 Newtons.
Explanation:
The key assumption in this problem is that the acceleration is constant along the path of the barrel bringing the pellet from velocity 0 to 155 m/s. This means the velocity is linearly increasing in time.
The force exerted on the pellet is
F = m a
In order to calculate the acceleration, given the displacement d,
we will need to determine the time t it took for the pellet to make the distance through the barrel of 0.6m. That time can be determined using the average velocity of the pellet while traveling through the barrel. Since the velocity is a linear function of time, as mentioned above, the average is easy to calculate as:
This value can be used to determine the time for the pellet through the barrel:
Finally, we can use the above to calculate the force:
answer:
liquids have he ability to change shape
liquids flow even with some resistance
liquids have a definite volume
liquids have molecules that slip past each other
