Thee plimsoll line in fresh water and in salt water?
The Plimsoll line in fresh water marks the maximum point to which a ship can be loaded safely without sinking. In salt water, the same principle applies, but the Plimsoll line will be slightly lower due to the higher density of salt water compared to fresh water. This ensures that ships are loaded appropriately for different water conditions to maintain stability and safety.
What system is responsible for sensing vibrations in the water on a goldfish?
When you look very closely at a goldfish you will see a row/line of what appears to be dots along the side of the fish. This line is called a "Lateral Line" it consists of tiny sensors that are receptive to many signals including variations in pressure. This "Lateral Line" is the part of the fish responsible for sensing the vibrations in the water.
What happens if the plimsoll line is below the level of the water?
The plimsoll line is a reference mark painted on the bow of a ship. If the line is below the water level, the ship is overloaded. There are lines for when on fresh water and when on salt water.
How can I effectively cut long stem roses to ensure they stay fresh and beautiful for a longer period of time?
To effectively cut long stem roses for longer freshness, use sharp scissors to make a diagonal cut at a 45-degree angle, trim any leaves that will be below the water line, and place the stems in water immediately. Change the water every 2-3 days and re-cut the stems every few days to help the roses stay fresh and beautiful for a longer period of time.
What is the primsol line?
Primsol line is a line that has many waters applied to it. Such as Tropical Fresh water (TF) - Fresh water (F) - Tropical salt water (T) - Summer salt water (S) - Winter salt water (W) - Winter Northern Atlantic water (WNA). It is in that exact order read above. TF | | -F | | -T | | -S | | -W | | -WNA !
What if your vacation includes fishing trip to coastal Bay where fresh water meets the ocean water You're fishing for a type of fish that lives in the salt water Would you put your fishing line in the?
you can put your line in the water where the fresh meets the ocean. many saltwater fish can thrive in fresh water, a good example is the red drum, however the salt water fish cannot reproduce in an isolated freshwater area.
An area near a coast line where river meets ocean mixing fresh and salt water?
the answer is estuary
Do the dots on the sides of a Goldfish tell you its gender?
No. Those dots are called the Lateral Line. It is a series of sensors that lets goldfish feel changes in water currents. The Lateral Line lets schools of small fish stay together, even turning in the same direction almost simultaneously. Sometimes the fish can even sense the movement in the water that means a larger fish is sneaking up on them from behind!
How to prepare hydrangeas for a vase to ensure they stay fresh and beautiful?
To prepare hydrangeas for a vase, cut the stems at an angle, remove any leaves that will be below the water line, and place them in a vase with fresh water. Change the water every few days and recut the stems to help them stay fresh and beautiful.
How can I create a small goldfish pond in my backyard?
To create a small goldfish pond in your backyard, you will need to choose a suitable location with access to sunlight and shade. Dig a hole for the pond, line it with a pond liner, and add water. Install a pump and filter to keep the water clean and oxygenated. Add aquatic plants and rocks for decoration. Introduce goldfish to the pond once the water has been treated and is at the right temperature. Maintain the pond by regularly cleaning the filter, monitoring water quality, and feeding the fish appropriately.
Do ships in the general lakes need more or less ballast than ocean-going ships?
Ships need more ballast in the ocean because the salt helps to keep them a float.What we know is that salt water is about 3% more dense than fresh water and that ships use the water they are floating in for ballast.Say an ocean ship needs 10 tonnes of ballast to get to it's stable water line. The volume of 10 tonnes of seawater would equal 9.7m3.That same ship will float slightly lower in fresh water since fresh water is less dense. It will need 3% less ballast weight (9.7 tonnes) to get to the same stable water line in fresh water. The volume of 9.7 tonnes of fresh water would equal 9.7 m3.So, the ship in the ocean requires 3% more ballast weight than the ship in fresh water, but the ballast volume is the same in both cases.
Is a line longer than a line segment?
A line extends forever into space and a line segment is a segment or part of a line, so a line is longer than a line segment.
