The energy would be transferred from the objects. Also do not forget, add direction to your answer.
For this case we have that by definition, a micrometer is equivalent to a thousandth of a millimeter, that is, 0.001 millimeters.
Then, in other words, we have 0.001 millimeters in a micrometer.
Answer:
In a micrometer there are 0.001 millimeters.
The wires that will have the least resistance is :
C. A short thick wire
in order to get the least resistence, you need the wire to be the lowest in length and the highest in Area
hope this helps
Na is in the first column on the periodic table so therefore it would have 1 valence electron
D 1
Answer:

Explanation:
We are given that three resistors R1, R2 and R3 are connected in series.
Let
Potential difference across 
Potential difference across 
Potential difference across 
We know that in series combination
Potential difference ,
Using the formula

Hence, this is required expression for potential difference.
