How could finding the density of the cube you identify it?

Hey there!

Finding the density of an object, such as a cube, can help you identify an object since not every object has the same density. They can also let you know if an object is made up of a pure substance or not.

One real life example would be determining if a piece of jewelry is made purely of gold. Since gold, regardless of shape and/or size has a density of 19.32 grams per cubic centimeter, you can figure out if it is pure gold by dividing its mass by its volume to see if you get 19.32 grams per centimeter.

Hope this helps and have a marvelous day!

Perhaps seek some professional ? it isn't very asking some children who are just trying to find out answers to homework.also, it seems professional would actually be good to you. obviously it isn't going to magically fix your depression, but it'll do something. drugs, smoking weed, it won't do much, especially if your husband is against it. if you do it he'll dislike it. but talk to him, try and get him to listen to you, and figure everything out together, okay? there's a website- maybe it can offer some ?

The answer is  the potential energy of the bob at position b is 1.47 joules.if the maximum height of the bob is 0.45 meters when it swings back,1.323   joules of energy was transformed to thermal energy.hope this
