The answer is Wind erosion
Answer:
C) seems to be the correct one
Each alpha particle emitted decreases the mass of the nucleus by 4 and decreases the atomic number by 2.
Also, each beta particle will increase the atomic number by 1.
So if C emits 5 alpha particles the atomic mass decreases by 20 and the atomic number decreases by 10. Then emission of 2 beta particles brings the atomic number up to minus 8.
So a total of 7 particles have been emitted and the number of alpha particles emitted exceeds the number of beta particles emitted.

Acceleration will always be samei.e.
Acceleration=g= 9.81 m/s^2
<u>Given</u><u> </u><u>-</u><u> </u>
- Velocity (v) = 12.1 m/s
- Time (t) = 8.2 sec
<u>To</u><u> </u><u>find</u><u> </u><u>-</u>
<u>Solu</u><u>tion</u><u> </u><u>-</u><u> </u>
★ Acceleration = velocity/ time
→ A = 12.1/8.2
→ 1.47.... m/s²
