Earth's gravitational potential energy: gpe = mgh = gravity (9.81m/s? ) mass (kg) x height (m) kinetic energy: ke = my? how would you calculate the gravitational potential energy of a 2 kg bottle of soda falling off of a kitchen table that is 0.76 m tall? 9.8 o a. 312/076? o b. (20.76) o c. (2)(0.76)9.8 od. (0.76)/27

An observation that requires measurement is called quantitative observable or qualitative

Which metal exist in liquid state and can be cut with knife ?

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.
