Carsen Herrera · Answer 1

The correct answer is the speed accuracy decreases

Explanation:

Before examining the final statements, let's review the uncertainty principle

Δx Δp> = h ' / 2

h ' = h / 2π

This is because the process of measuring one quantity affects the measurement of the other.

Let's review the claims

The speed of the particle is proportional to the moment

p = mv

Therefore, if the position is measured more accurately (x) the accuracy of p must decrease

Δp = h ' / 2 Δx

The correct answer is the speed accuracy decreases
