Chapter 18, Problem 78QAP

Interpretation Introduction

(a)

Interpretation:

The amount of energy in J per alpha particle needs to be determined.

Concept introduction:

According to Coulomb’s law, the activation energy for the fusion of two deuterons can be calculated as follows:

$E=\frac{8.99\times {10}^9{q}_1{q}_2}{r}$

Here, $q_1$ and $q_2$ are two charges and r is distance between them.

Interpretation Introduction

(b)

Interpretation:

The velocity of deuteron for collision needs to be determined.

Concept introduction:

The energy is related to velocity as follows:

$E=\frac{m{v}^2}{2}$

Here, m is mass and v is velocity.
