Light has nothing to do with its weight. It weighs the same in moonlight as it does in sunlight.
The Cargo must weigh less than the ship, and although heavy, ships are less dense than water.
No - more on Earth - in orbit you're weightless.
Ships come in different sizes, and all sizes have different weights. The only sure thing is that they will weigh less than the amount of water they displace.
depends on the ship
7 foot cargo ship probaby dosent weigh over 5000 lbs.
Yes, but not much. A ship is more buoyant in seawater, and thus less of the hull is in the water (thus less resistance).
The Titanic weighed 1000 tons more than her sister ship Olimpic , many say it is because Titanic carried 100 more 1st class cabins.
Its' anchor, silly!
You may feel less movement on a cruise ship when you are in the middle of the ship, closer to the waterline. This area tends to experience less rocking and swaying compared to the front or back of the ship.
50 tons
A cargo ship
It would be more expensive to ship a car to ship a classic car from Los Angeles to England.
