Answer:
So, you're going to need the equation ρ = ρo [1 + α(T-To)]
1.59x10^-8 ohms*m is your ρo because that is measured at your reference temperature (To), 20◦C. T is your 6◦C and α is 0.0038(◦C)−1. So, using that you solve for ρ. If you keep up with the units though, you notice it comes out to be ohms*m and that isn't what you want.
So, the next equation you need is J=σE where E is your electric field (3026 V/m) and σ is the electrical conductivity which is the inverse of your answer you got in the previous equation. So find the inverse of that answer and multiply it by your electric field and that will give you the current density.
I hope this helps!
Explanation:
if your not able to reverse it that means it is a chemical change and with toast you cant reverse the color if the color has changed that most likely means it is a chemical change.
Weight = Mass times Acceleration due to gravity.
Weight = 10 kg times 9.8 m/s^2
Weight = 98 kg
