1. Emission of charged particles is  Radiation

2.  Particles penetrate through paper.  Alpha

3. Particles penetrate aluminum.  Beta

4. A mass less emission is  decay of Electron

5.  Helium is released during an alpha decay.

6. Negatively charged is released during a beta decay.

7. Alpha particles are  Positively charged particles.

8. Beta particles are  Negatively charged particles.

9.  Gamma rays are emitted usually after an alpha or a beta decay.

10. The energy emitted by an  nuclei is called a radiation Unstable.

at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6
