Ques:Q: There are six fundamentally different kinds of nuclear decay reactions, and each releases a different kind of particle or what? Read this paragraph and choose the correct option from the provided answers: an identical particle that has been ejected from a heavier nucleus. There are six fundamentally different kinds of nuclear decay reactions, and each releases a different kind of particle or energy. The essential features of each reaction are shown in Figure 20.4 "Common Modes of Nuclear Decay". The most common are alphaand beta decay and gamma emission, but the others are essential to an understanding of nuclear decay reactions. Figure 20.4 Common Modes of Nuclear Decay. Choices: - protein - mineral - mass - energy A:

Ans:energy

Ques:Q: Energy constantly changes back and forth between kinetic and what type of energy? Read this paragraph and choose the correct option from the provided answers: Energy also constantly changes back and forth between kinetic and potential energy. Kinetic energy is the energy of movement. For example, a ball falling through the air has kinetic energy because it is moving ( Figure below ). The random motion of molecules is due to kinetic energy, and the driving force behind diffusion. Choices: - practical - physical - mechanical - potential A:

Ans:
potential
