Why do things float in water? Objects are made up of very tiny molecules. Molecules can be packed in close together like in a rock or more spread out like in bubble wrap. The positioning of molecules affects the density of an object. Objects with tightly packed molecules are more dense th...
ByBen Pauley Gravity is an attractive force that gets stronger the more massive something is. We don’t float off the Earth and the Earth never flies away from the Sun. Therefore, one might expect super massive objects like galaxies to only ever grow as loose materials fall onto them. But...
A block of wood is so loaded that it just floats in water at room temperature. What change will occur in the state of floatation, if some salt is added to water? Give reasons. View Solution A block of wood has a mass of25g. When a5gmetal piece with a volume of2cm3is attached to...
Then why do you float? Maybe I should talk about how you feel weight. What is your apparent weight? Let me go ahead and say that what you are feeling right now isn't really gravity. Suppose I start with some examples. Example 1: Go stand in an elevator. Do not push the buttons. ...
Why does the human body float in water? Why do waves refract? Why do denser objects sink? Why is the thermocline of a body of water important? Why does the sclera not have lymphatics? Why does the level of water seem to not rise when salt is dissolved in water? Why are krill so...
I would like to clean up my Excel VBA project by exporting all code modules and then re-importing them. I understand that there is no VBA Project export or...
Why does a needle need to be dry to float on water? Explain in detail. Why does ice float on water? Why do objects float in liquids denser than themselves? Why is evaporated water so clean? Why should liquids never be poured or used near a balance? Why is water more dense than ice...
Spacetime is exactly what it sounds like: the three dimensions of space – length, width, and height – combined with the fourth dimension – time. Using some very brilliant math, Einstein was the first person to realize that the laws of physics work in a universe wherespace and time are ...
// Get the objects; no need to cast to String for(GenericContainer<String> obj:genericList){ String objectString = obj.getObj(); // Do something with the string...here we will print it System.out.println(objectString); } Listing 4 ...
—Why do cats and dogs love a good head scratch? If you're curious what your cat has to say, it's possible to encourage communication, Wright said. If humans respond with words and attention to their cats' chirps and meows, they can create a back-and-forth — almost like a conversati...
