Lab Report of Archimedes Principle

Experiment 7
Title: Archimedes Principle
Objective: To use Archimedes principle to desexualise the density of an target area more dense than water.
Introduction:
A body wholly or partly immersed in a fluid is supported by a violence make up to the weight of the fluid it displaces. The buoyant force can be considered to act vertically upward. Archimedes principle is important for the construction of ship, numbfish and so on.
Materials: newton gauge, metal samples, beaker, and measuring cylinder electronic balance.
Method 1: Determine the weight of each end by using electronic balance.
Method 2: burgeon forth some water into the measuring cylinder, recorded the values, and put the determinationive lens into the measuring cylinder. Measure the increase of volume, which is the volume of object.

Discussions
Here are some working footmark which is related to Archimedes principle from this experiment, taking pendulum bob as an example.




-From begging, we brisk 1g/cm3 ,density of water from 100ml of water.
P=mv ,100g100cm3 =1 g/cm3
To fetch the density of pendulum boband reason why the pendulum bob will come down…
a) Mass of water displaced
=pv
=1 g/cm3 x 4cm3=4g
b) Mass of object in water=25.56g
c)Mass of object in ambiance =mass in water + mass of water displaced
=25.56g+4g
=29.56g(same as the reading in electronic balance for pendulum bob)
d) Density of object =mass of object in airvolume displaced=29.56g4cm3=7.39 g/cm3
e) buoyant force=weight fo water displaced
=4/1000kg x10NkgN-1=0.039N
Weight of object=25.56/1000kgx10NkgN-1=0.25N
Thus the object willsink...If you want to get a rise essay, order it on our website: Orderessay
