because they want to
The surface area of the raft displaces the water forcefully which causes float
About 15.
A raft is very buoyant, and displaces very little water, the material it is made from is lighter than water, which makes them float very well.
The upthrust force needed to float on water is equal to the weight of the person (or raft) and any additional load they are carrying. As long as the upthrust force is greater than or equal to the total weight of the person and the raft, they will float on the water.
Umm, no because there is no water to float on.

About the only thing that is the same is that both float. A coracle is round and usually made of inter woven reeds. A raft can be made of almost anything that has bouyancy.
The independent variable when building a raft powered by surface tension would be the raft design or materials used. By changing these factors, you can observe how they affect the ability of the raft to float and move on the water surface due to surface tension.
To make plasticine float, you can shape it into a boat or raft-like structure with a concave base. By redistributing the weight and displacing enough water, the plasticine will float instead of sink.
source of the word is from IndiaHindi ḍi·gī, variant of ḍe·gī, ḍe·gā, float, raft.
A life raft would not be useful on the moon as there is no water or large bodies of liquid to float on. The moon's surface is airless and its gravity is much weaker than Earth's, so a life raft would not function in that environment.
You put on/in a ship or raft etc. That makes it float better or makes in more stable
