<span><span>1) Calculate the total number of nucleons (protons and neutrons) in the nuclide
<span>--> If the number of nucleons is even, there is a good chance it is stable.
</span></span><span><span>
2) Are there a magic number of protons or neutrons?
</span>--> 2,8,20,28,50,82,114 (protons), 126 (neutrons), 184 (neutrons) are particularly stable in nuclei.
</span><span>
3) Calculate the N/Z ratio.
<span>--> Use the belt of stability (Figure 1) to determine the best way to get from an unstable nucleus to a stable nucleus</span></span></span>

DNA is packaged into these<br> compact units
Wittaler [7]

Explanation:

Chromosomal DNA is packaged inside microscopic nuclei with the help of histones. These are positively-charged proteins that strongly adhere to negatively-charged DNA and form complexes called nucleosomes. Each nuclesome is composed of DNA wound 1.65 times around eight histone proteins.

A bob of mass of 0.18 kilograms is released from a height of 45 meters above the ground level. What is the value of the kinetic
Drupady [299]

We can assume that all<span> gravitational potential energy is converted into kinetic energy of the object.</span><span>

<span>Hence, </span>GPE = KE

Where GPE is gravitational Potential Energy (J) and KE is Kinetic Energy (J)

GPE = mgh

<span>Where, m is the mass of the object (kg), g is acceleration due to gravity (9.8 m s</span></span>⁻<span>²) and h is the height to the<span> object from ground (m).</span></span><span>

m = 0.18 kg
g = 9.8 m s</span>⁻²<span>
h = 45 m

Hence, 
       GPE = 0.18 kg x 9.8 m s</span>⁻² x 45 m<span>
                = 79.38 J
                ≈ 79 J

<span>Hence, </span>KE = GPE = 79 J

<span>Hence, the answer is '79 joules'.</span></span>
