Asolid object has a density of 2.85 g/cm3. according to archimedes, what can be done to make this object float in water?

nothing can make this object float because it is too dense.
cut the object down to one third of its current size.
reshape the object so that it displaces more than its own weight of water. decrease the density of the object by making its volume smaller.

Select all that apply. a beta particle: is electromagnetic energy is an electron has zero charge is emitted from the nucleus has a +2 charge has a -1 charge

Identify one disadvantage to each of the following models of electron configuration: -dot structures -arrow and line diagrams -written electron configurations type in your answer below. (answer) -dot structures do not show the distribution of electrons in orbitals and take up a lot of space. -arrow and line diagrams take up a lot of space and make it difficult to count electrons. -written configurations make it easy to lose count of electrons and do not show the distribution of electrons in orbitals.
