Answer: It wouldn't be as modern as today is we would be back to using oil and other things from back then there wouldn't be cars everything would be less machined.
Answer:
Over such small distances, digital data may be transmitted as direct, two-level electrical signals over simple copper conductors. This results from the electrical distortion of signals traveling through long conductors, and from noise added to the signal as it propagates through a transmission medium.

Inertia is the force in play here
Answer:
the field is not zero anywhere on the x axis (except at infinity)
Explanation:
From the Coulomb's law we have electric field intensity as:

where:
permittivity of free space
charge due to which the field is generated.
distance from the charge
So, from the above relation:
Electric field due to a charge can only be zero at infinity.
