Elasticity: finding weight density

In summary, to find the new weight density A1 of water when the pressure changes from Po to P1, you must first understand that water is not completely incompressible and its density does change slightly with pressure. To calculate this change, you will need to look up the bulk modulus of water.

you have been given weight density Ao of water at normal atmosphere pressure Po and you asked to find its new weighty density A1 if the new pressure s P1.

I tried to solve it assuming that if there is a compression( increase of pressure) the weighty demsity decreases. But how to find it and pove it?

Water is incompressible so its density does not change with pressure.

I have never heard of 'weight density' or 'weighty demsity' so I assume you mean density.

There are a lot of typos in your submission. Make a habit of reading what you have typed.

Water is only 'almost incompressible'. Not completely. At bottom of the ocean depths its a percent or two more dense just due to the pressure. You need to look up the bulk modulus of water.
 

1. What is elasticity?

Elasticity is the measure of an object's ability to return to its original shape after being stretched or compressed.

2. How is elasticity related to weight and density?

Elasticity is related to weight and density because an object's weight and density can affect its ability to stretch or compress. Heavier and denser objects tend to have lower elasticity, while lighter and less dense objects have higher elasticity.

3. How do you calculate weight density?

Weight density is calculated by dividing the weight of an object by its volume. The formula for weight density is W/V, where W is the weight of the object and V is its volume.

4. What factors can affect the elasticity of an object?

Some factors that can affect the elasticity of an object include temperature, material composition, and the amount of force applied. Objects made of different materials will have different levels of elasticity, and extreme temperatures can also impact an object's elasticity.

5. How is the concept of elasticity used in real life?

Elasticity is used in many real-life applications, such as in the design of buildings, bridges, and other structures. It is also important in the manufacturing of products, such as clothing and rubber band, where elasticity is needed for proper function. Understanding elasticity can also help in predicting and preventing potential accidents or failures in various materials and structures.
