The shape of the earth is an <span>oblate spheroid.</span>
Can’t top the first answer so check that out. My boy is a legend.
We have the following values used to solve this:
For ⁴₂He:
No of protons: 2
No of neutrons : 2
Mass of proton: <span>1.00728 amu
Mass of neutron: </span><span>1.00867 amu
Atomic mass: </span><span>4.002603 amu
The formula to solve for the mass defect is:
md = (mp + mn) - mo
md = (2x</span>1.00728 + 2x1.00867) - 4.002603
md = 0.029297
Therefore, the mass defect is 0.029297 amu
D. K = Potassium (use your periodic table)
Most of the time the towns get flooded and many people die and lose their homes and their jobs, businesses by the floods and the natural environment is destroyed ,air pollution is produced, the ecosystem could be disrupted and dams are known to fall over and dams are really expensive to build, The dams also cause geological damage, example earthquakes and spills happen.
