That would depend on your type of transport.
I don't believe it will penetrate a 12 inch diameter tree
The diameter of a 4-foot table is 48 inches, as there are 12 inches in a foot. If the table is round, its diameter would be 48 inches. If it is rectangular or square, the measurement would refer to the length of one side rather than a diameter.
16'. Diameter is the measure from the edge of a circle through the middle to the opposite end.
If you went directly from where you are standing straight through the earth until you got to the other side, the distance that you would travel would be the diameter.
The table would have to be at east ten feet in diameter.
we can't use jupiters moons for anything because fistly we can not get out that far to reach Jupiters moon and if we could it would take thousands of years and Jupiters Moons would be to big to do anything with anyway. so the answer to What could Jupiter's moons be used for? is....Nothing.
The star would take 1101 years to travel around.
If there is a service that provides that, then it would be thousands of pounds (at least). The ship would have to travel round half the world to get there.
The term "radius" typically refers to the distance from the center of a circle to any point on its circumference, which is a one-way measurement. In contexts like travel or mapping, a radius may indicate the distance from a central point outward, but it does not imply a round trip. For round trip distances, terms like "diameter" or specific round trip measurements would be more appropriate.
about 680 kilometers if you travel nix's diameter per hour then you would travel 8.5 hours
nothing would happen
If you describe a table as being 6 foot, that would normally mean that it is 6 feet long, and rectangular in shape rather than round. Only round tables have a diameter. The term doesn't apply to rectuangular tables.
