Do not forget that mass = <span>volume x density
</span>Mass of 1 cm^3 = Density[/tex]

Then eventually we can find <span>mass of 5 cm^3 : =
</span>

So the answer is D
<span>And that's it. I'm sure it will help.</span>
Answer: 1.3 *10^6 Ω*m
Explanation: In order to explain this problem we have to use the following expression for the resistence:
R=L/(σ*A) where L and A are the length and teh area for the wire, respectively. σ is the conductivity of teh Nichrome.
Then, from mteh OHM law we have V=R*I so R=V/I=2/3.2=0.625 Ω
Finally we have:
σ=L/(R*A)=1.3/(0.625*1.6*10^-6)=1.3*10^6 Ω*m
They both have a certain force. They are different because that force is different
Answer:
They would attract one another
Explanation:
The interaction between two like-charged objects is repulsive. ... Positively charged objects and neutral objects attract each other negatively charged objects and neutral objects attract each other.
