Hotel: Trivago (I’m bored if you can tell lol)
Answer:
a ship floats because of the mass and the parts of the ship help with staying on top of the water the buoyancy force is helpful for the ship to float which means weightless-airlessness and lightness.
Explanation:
Two facts that I learned during my research were narrowing down the research topic and setting appropriate goals.
When doing research, several aspects must be taken into account so that the research has good results and produces new knowledge. Here are two tips for proper research:
1. Limit the subject of the investigation: When conducting an investigation it is necessary to limit the subject so that it is easier to achieve an effective result. For example, time limits, a specific place, and more special aspects should be set to make the investigation more specialized.
2. Establish adequate objectives: When conducting an investigation it is necessary to establish objectives that can be achieved in the investigation. Highly ambitious goals can make research and information search difficult.
