If a wire 375 feet long has 500 ohms of resistance, what is the resistance of 1,000 feet of the same wire? a. 1,333 ohms
b. 187.5 ohms
c. 1,691 ohms
d. 750 ohms

D

Explanation:

set up a proportion:

375/500=x/1000

500x=375000

x=750.

So 750 ohms

Hope this helps ;D

that's what i got you can count the number of atoms

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
