Earthed to the Ground was created in 1984-05.
No, static electricity cannot build up on a conductor that is properly grounded (earthed). Grounding provides a path for the excess charge to flow into the earth, preventing the accumulation of static electricity on the conductor.

Front wheel bearings in a car should be well greased but have never heard of them needing to be earthed.
No.
As aircraft fly through the air, the friction causes them to become charged with static electricity. After an aircraft has landed there is a possibility of charges escaping to earth as a spark. Therefore, the aircraft should be earthed with a conductor as soon as it lands, allowing the charge that has built up to flow to earth.
If the kitchen in a property is not earthed, it raises a strong possibility that the rest of the house may also lack proper earthing. Electrical systems are typically designed as a whole, and if one area is not earthed, it suggests potential negligence or outdated wiring practices throughout the property. However, to confirm the earthing status of the entire house, a thorough inspection by a qualified electrician is necessary.
For earthed and un earthed XLPE cables, the IS 7098 part2 1985 does not give any difference in specification. The insulation level for cable for unearthed system has to be more. In simple statement the manufacturers states that 11 KV earthed cable is suitable for use in 6.6 KV unearthed system.The process of manufacture of cable is same. The size of cable will depend on current rating and voltage level.
yes
