Hey there!
According to Archimedes principle, an object floats if the bouyancy force exerted on it the fluid will balance its weight , which means FB=mg.
Also, the principle states that the bouyant force is the weight of the fluid displaced.
So, the amount of fluid displaced is the weight of the body.
And the formula for finding weight is
W = V×p×g
The "time signature" at the beginning of the piece tells how many beats there will be in each measure, and what size note will receive one beat. From there on, all the different size notes in the piece are figured from that. It can even change during the piece, but if that happens, then there has to be a new time signature at the place in the music where it changes.

There are quite a number of units to measure speed and depending on how fast an object is going, some are more preferred than others.
The units are:
- Metres per second - this is on of the most common units and is regularly used by runners.
- Kilometres per hour - used by cars, buses and generally objects that move adequately fast.
- Miles per hour - this is a substitute to kilometers per hour for countries using the imperial system or miles instead of kilometers.
- Knots - Represent nautical miles and are a unit of speed mostly used to measure wind and water speed.
- Feet per second - Not as popular but used in countries that don't regularly use metres.
- Mach number - for really fast objects going faster than sound.
