Fusion is the act of putting together ( fusing ) two items so that they become one. Fission is the act of dividing or splitting an item.
Yes, this is accurate. While "dark matter" might exist, it is still more of a theory, it is not yet defined properly. As far as we truthfully know, the entire universe is just matter and energy.
The force applied to raise the block would be 250N
<span>Young modulus E = stress/strain where E is the elastic modulus. We seek to calculate the the strain.
But we would have to get the stress first. Tensile stress = Force/Area. Force = 20100N. And the Area = 9.54* 13.9 = 132.606Nm^2.
Strain = stress/E.where E = 79. Hence we have 132.606/79 = 1.67</span>
