Explanation
The question is asking for the speed of the alpha particles. The speed of light is given as 300,000,000 m/s and the alpha particles are said to be moving at 7% of the speed of light. To find the speed of the alpha particles, we need to calculate 7% of the speed of light. This can be done by multiplying the speed of light by 0.07 (as 7% is equivalent to 0.07 in decimal form).
