If the accuracy in measuring the position of a particle increases, the accuracy in measuring its velocity will

Therefore the answer is the precision in the speed DECREASES

Explanation:

In quantum mechanics, we have the uncertainty principle that establishes that when the accuracy of the position increases the accuracy  the speed decreases, being related by the expression

               Δx Δv ≥  h'/ 2

                h' = h/2π

Therefore the answer is the precision in the speed DECREASES

b.transmitters send radio waves, and receivers capture radio waves.
