Omnipotence - correct answer - God can do anything that is intrinsically (non-contradictory) possible for God to do Omniscience - correct answer - God knows the future - God is immutable, so foreknowledge is nonexistent > *obj*: God would "change his mind" depending on what an agent chooses to do The Kalam Cosmological Argument - correct answer ...

Basic Postulates of Quantum Theory 1. Atoms and molecules can exist only in certain energy states. In each energy state, the atom or molecule has a definite energy. When an atom or molecule changes its energy state, it must emit or absorb just enough energy to bring it to the new energy state (the quantum condition). 2. Atoms or molecules emit or absorb radiation (light) as they change their energies. The frequency of the light emitted or absorbed is related to the energy change by a simp...

Describe the relationship between the frequency, wavelength, and velocity (speed) of a wave. - AnswerThe more times the wave is passing through a point in space = a higher frequency, the higher frequency creates a smaller wavelength, which is why the smallest wave is a gamma wave, it has the highest frequency and the shortest distance between waves, the velocity can be measured in m/s and is composed of frequency and wavelength Calculate any one (frequency, wavelength, or velocity) given the...

Atomic number - correct answer the number of protons in the nucleus of an atom. Atomic radius - correct answer The atomic radius of a chemical element is a measure of the size of its atoms Aufbau principal - correct answer electrons orbiting one or more atoms fill the lowest available energy levels before filling higher levels Chemical family - cor...

Omnipotence correct answers - God can do anything that is intrinsically (non-contradictory) possible for God to do Omniscience correct answers - God knows the future - God is immutable, so foreknowledge is nonexistent > *obj*: God would "change his mind" depending on what an agent chooses to do The Kalam Cosmological Argument correct answers (1) everything that begins to exist has a *cause* (2) the universe began to exist > the number of past events is continuously augmented, ...
