Answer:
E
Explanation:
Using Coulomb's law equation
Force of the charge = k qQ /d²
and E = F/ q
substitute for F
E = ( K Qq/ d² ) / q
q cancel q
E = KQ / d²
so twice the distance of the from the point charge will lead to the E ( electric field ) decrease by a 4 = E/4. E is inversely proportional to d²
It is (C): human.
This is more like forensic sciences or biology btw.
Answer:
∆p=(m2v)kg.m/s
Explanation:
∆p=mv where v=2v. hence ∆p=m2v
Iron rich minerals in rock pointed in one direction the switch to the exact opposite direction. what supports this idea is that Earth's magnetic field goes through pole reversals <span>
