matt built a boat with a mass of 320g. When he tried it out, he found that it displaced 260g of water. did the boat sink or floa
1 answer:
When we put an object inside the water then the submerged part of the object will displace water.
this weight of displaced water is known as buoyancy force on the object
Now as we know the principle of flotation if buoyancy force due to fluid on the object is more than weight then object will easily float
So here we can say that
now here we know that buoyancy force is the weight of liquid which is displaced and that weight must be more than weight of object for flotation
So here we can say
So here we know that mass of object is 320 g
mass of liquid displaced 260 g
here
mass of liquid displaced < mass of object
So it will not float and it will sink

Answer:
Because the wavelengths of macroscopic objects are too short for them to be detectable.
Explanation:
Wavelength of an object is given by de Broglie wavelength as:
Where, 'h' is Planck's constant, 'm' is mass of object and 'v' is its velocity.
So, for macroscopic objects, the mass is very large compared to microscopic objects. As we can observe from the above formula, there is an inverse relationship between the mass and wavelength of the object.
So, for vary larger masses, the wavelength would be too short and one will find it undetectable. Therefore, we don't observe wave properties in macroscopic objects.
