In tropical seas the water is warmer so it is less dense than in colder areas. The ship sinks lower in water, as cargo is loaded, to displace a greater weight of water. Fresh water also produces less upthrust than sea water.
tropical fresh water produces less upthrust in winter than the North Atlantic because tropical water is warmer than the cold water of the North Atlantic. I need one more reason though: for homework tropical fresh water produces less upthrust in winter than the North Atlantic because tropical water is warmer than the cold water of the North Atlantic. I need one more reason though: for homework
tropical fresh water produces less upthrust in winter than the North Atlantic because tropical water is warmer than the cold water of the North Atlantic. i need one more reson too though!Its also becasue salt water is denser than "fresh water" therefore it will provide a greater upthrust like with mercuary that will provide even more up thrust becase it has an even greater density
because it is warmer than Atlantic water and has no salt therefore less buoyancy
Assuming its weight hasn't changed, then as it is floating, the upthrust on it equals its weight and so is the same. What WILL change, however, is how deep in the water it floats. The upthrust is provided by the weight of the displaced volume of water, the volume of which depends upon the density of the water which depends upon the temperature and saltiness (amongst other things) of the water. As freshwater is less dense than [briny] sea water, it will require more volume for the same weight and so the ship will float deeper in freshwater than in [briny] sea water. This can be seen in the load lines on the "Plimsoll Line" where the Freshwater line is much higher than, say, the Winter North Atlantic line (the latter being more salty and colder, and so much more dense) meaning that for the same load, that the waterline in Freshwater will be much higher up the ship than in Winter North Atlantic (or alternatively, the ship will float much deeper in the Freshwater than the Winter North Atlantic).
YES...and examples are flying objects! Interestingly,Any liquid or gas produces upthrust. For example, the upthrust of air keeps a hot air balloon up.
Upthrust, I don't understand what you mean...
Upthrust is a Contact Force. :)
upthrust is a scalar or vector
upthrust means the force that keeps the force up
it provides 30 upthrust .
Upthrust is a contact force :)
Upthrust cancels weight out, weight is there but you do not feel it.
