Discuss on law of physics studies and its applications in daily life
Answers
Answer:
we have to discuss one law of Physics studied and its application in daily life.
solution : physics is nothing but the study of the nature and properties of matter and its energy. so it's obvious that every law of physics has importance in our daily life.
there are hundreds of laws of physics but if you asked me only one to explan with its application in our daily life, i must consider Archimedes' principle.
Archimedes' principle : it is one of the most important fundamental law of physics which helps us to find the volume of object of irragular shape, helps to make ship and boat and find the density of object.
" when a object is partially or fully submerged in a liguid. an upward force (known as buoyant force) acting on the body which is equal to the weight of liquid displaced by the object. "
this buoyant force, F = ρVg
where ρ is the density of the liquid , V is the volume of displaced liquid and g is acceleration due to gravity.
application of Archimedes' principle :
this principle is used in designing the ships and submarines.
lactometer which is used to measure the purity of milk is based on Archimedes' principle.
hygrometer which is used to measure the density of liquid, is also based on Archimedes' priniciple.
