Answer:
Europe and most other countries in the world use a voltage which is twice that of the US. ... Originally Europe was 120 V too, just like Japan and the US today, but it was deemed necessary to increase voltage to get more power with fewer losses and less voltage drop from the same copper wire diameter

<u>Yes</u>
Explanation:
In such a case, one way to check the <em>credit charge</em> is to <u>contact your bank, </u>doing so would allow the bank to check your account properly to determine where the transaction was originated from.
Another way you could check is to contact the online merchant where such a transaction was initiated.

Electron concentration 
Electron diffusion coefficient is
Electron mobility is 
Electron current density 
Generally the equation for the semiconductor is mathematically given by

Therefore



Answer:
Density of oil will be 897.292 kg
And specific gravity of oil will be 0.897
Explanation:
We have given density of oil is 1.74 slugs/
We have to convert this slugs/
into kg/
We know that 1 slugs = 14.5939 kg
So 1.74 slug = 1.74×14.5939 = 25.3933 kg
And 1 cubic feet = 0.0283 cubic meter
So 
Now we have to calculate specific gravity it is the ratio of density of oil and density of water
We know that density of water = 1000 kg/
So specific gravity of water
