On ships, 3 phase 3 wire system is used and neutral of generator reamains hanging or floating or isolated. All machineries onboard a ship are earthed to the ship's hull. The advantage of this kind of system is that if earth fault occurs on any one of the phases, the supply will not get afftected and machinery keep on working. This is the priority on marine platforms. Howevr, if one more earth fult occurs on the remaining phases, this condition will become like short circuit throught ship's hull and protection will operat to isolate the defective source and power supply for the machinery will be interrupted.

What are the different theories about the shape of the earth?
The main theories about the shape of the Earth are the spherical Earth theory, which posits that the Earth is a sphere, and the flat Earth theory, which incorrectly suggests that the Earth is flat. The spherical Earth theory is supported by scientific evidence such as images of the Earth from space and the way ships disappear over the horizon.
Why do ships seem to disappear over the horizon from the bottom upwards?
Ships appear to disappear over the horizon from the bottom upwards due to the curvature of the Earth. As a ship moves away from an observer on the shore, the bottom part of the ship becomes obscured by the curvature of the Earth before the top part, creating the illusion that the ship is sinking into the horizon.
Would enormous alien ships entering Earth's atmosphere have any impact on the weather?
Yes, enormous alien ships entering Earth's atmosphere could potentially have an impact on weather patterns due to their size and the disturbance they would create in the atmosphere. This could lead to changes in temperature, wind patterns, and possibly precipitation in the surrounding areas.
What did Aristotle think about the shape of earth?
Aristotle believed that the Earth was spherical in shape because of the observed curvature of its shadow during a lunar eclipse, the way ships disappear over the horizon, and the circular shape of the Earth's shadow on the moon during a lunar eclipse.
Why do you think the earth is not flat?
The earth is not flat because there is overwhelming evidence from science, including satellite images, GPS technology, and the way ships disappear over the horizon, that clearly demonstrates the earth is a spherical shape. Additionally, the laws of physics and gravity support the idea of a spherical earth.
How do observations of ships sailing out to sea support the idea of a round earth?
By the ships disappearing below the horizon
Where did Anne Bonny rob ships?
Some where on earth.
Why do ships disappear over the horizon?
Ships disappear over the horizon due to the curvature of the Earth. As a ship moves away from an observer, the Earth's surface curves downward, eventually blocking the view of the ship from sight.
Columbus had 3 ships to go to new earth what ship Columbus drive?
The Santa Maria
How do sailing ships provide evidence thatearth is round?
Ships can circle the world by water and end in the spot where they began, proving the Earth must be round to the contrary belief that it was flat.
Chinese ships during the ming dynasty were diffrent than European ships because?
Allegedly, ancient Chinese SEA-GOING vessels were built for exploring the earth; consequently they were built larger. The Chinese may have known that the earth was far vaster than their European counterparts. Recall, if you will, that Europeans believed that the world was FLAT and not round! chinese ships were much heavier

Why did people disagreed about the shape of the earth?
Because when they sailed on ships they went straight and didn't think they went around
When did the Bermuda triangle first gets its name?
It started when a lot of ships and planes went missing from the face of the earth.
Why do ships seem to disappear over the horizon from the bottom upwards?
Ships appear to disappear over the horizon from the bottom upwards due to the curvature of the Earth. As a ship moves away from an observer on the shore, the bottom part of the ship becomes obscured by the curvature of the Earth before the top part, creating the illusion that the ship is sinking into the horizon.
Why is it that ships disappear over the horizon?
Ships appear to disappear over the horizon due to the curvature of the Earth. As a ship moves away from an observer, it eventually reaches a point where the curvature of the Earth blocks the line of sight between the observer and the ship, making it seem as though the ship has disappeared.
Have manned space ships traveled further from earth than the moon?
I don't believe so, considering it would be awfully difficult to reverse a huge hung of metal traveling at insane speeds, and we haven't been to mars or Venus, so that sort of mission would be a suicide.
