How do scientists determine the number of neutrons in an isotope of an atom?
ikadub [295]
D.  The atomic mass in amu is basically the number or nuclei since the mass of the electrons is negligible.  For a given atom (element) the number of protons is fixed.  Say the element has 10 protons.  If the atomic weight is 14 atomic mass units (amu), you know that there are 4 neutrons, since both neutrons and protons are 1 amu each and there are 10 protons

A 1.5m wire carries a 3 A current when a potential difference of 86 V is applied. What is the resistance of the wire?
Iteru [2.4K]
We know, R = V / I
Here, V = 86 V
I = 3 A

Substitute their values, 
R = 86 / 3
R = 28.67 Ohm

In short, Your Answer would be 28.67 Ohms
