displacement and buoyancy
buoyancy is the ability to float in a liquid such as water. archimedes’s experience with water displacement in the bath gave rise to archimedes’s principle, which states that the upward buoyant force, or push, exerted on a body immersed in a fluid is equal to the weight of the fluid the body displaces. in technical terms, buoyancy is the upward force exerted by a fluid on a body when the body is immersed in the fluid.
part a
making use of archimedes’s principle, displacements, and buoyancy, explain why some objects float on water, but others do not. use the diagram to you decide.
part b
the titanic is one of the most famous passenger ships in history. search the internet to determine how much the titanic weighed in metric tons.
part c
the hull of a ship should be the only portion of a ship that is below the water. therefore, at a minimum, how many tons of sea water should the hull of the titanic displace while it’s in water?

f . i can go whenever i feel like it bc it is confidential meaning only i would know how much i deposited besides the bank and they wouldnt care bc when you make a deposit you are using their services which means they are using there competition and gaining more customers

and if they dont well then thats less customers for them in a less profitable way

plz mark brainliest

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:

the cross section of an object is the shape you get when you cut straight through an object.

thus the cross section of the human hair is a circle. hence the cross sectional area is the area of a circle and area of circle is :

a = 3.14 × r²

we are given that the average width of human hair is = 4 × (1 / 10³) cm.

so the diameter of the circle is = 4 × (1 / 10³) cm.

∴ radius r = (diameter/2) = 2 × (1/10³) cm

now area a = 3.14 × (2 × (1/10³))² cm²

scientific notation is a standard way of writing very large and very small numbers so that they’re easier to both compare and use in computations. to write in scientific notation, follow the form

n × 10 ᵃ

where n is a number between 1 and 10, but not 10 itself, and a is an integer (positive or negative number).

so area can be rewritten in scientific notation as :

⇒ 3.14 × 4 × (1/10⁶)

⇒ 12.56 × 10 ⁻⁶ cm²

⇒1.256 × 10⁻⁷ cm²
