Answer:
The shorter the blades(edges) are the more pressure can be applied. Because iron is a more dense and tougher material the edges must be short in order to provide enough pressure/force to break the bonds within the atoms.
Explanation:
<h2>
Magnitude of force doubles.</h2>
Explanation:
Force between two charges is given by
where q₁ and q₂ are charges and r is the distance between them.
Here one charge is doubled with keeping all others same.
q₁ = 2 q₁
We have
Magnitude of force doubles.
Answer:
Hey
on August 6, 1945, the atomic bomb was released. the only remains of the poor people in Hiroshima were the shadows of the last place they stood.
The energy that was released by the atomic bomb was transferred by nuclear fission (The processes at which atoms split and give off energy).
In the core of the sun, the process is different from that of fission. it is called nuclear fusion (the process in which atoms [of hydrogen] are smashed together into helium and release tremendous amounts of energy).

Answer:
1) Li = 0048678 kg -m^2/s
2) 0.129483 joule
3) 3.4745 Rad/s
4) 0.08456 joule
Explanation:
1) INITIAL ANGULAR MOMENTUM
we know that
2) INITIAL ROTATIONAL KINETIC ENERGY
3) FINAL ANGULAR VELOCITY
from conservation of angular momentum
Li =Lf
= 3.4745 Rad/s
4) FINAL ROTATIONAL KINETIC ENERGY
