You Want to Make Simultaneous Measurements of the Position and Momentum

question 42

Multiple Choice

You want to make simultaneous measurements of the position and momentum of an electron and a proton that are moving along a straight line. An alternate statement of the uncertainty principle involves relationship between position $\Delta$ x) and momentum $\Delta$ p) uncertainties in the form $You want to make simultaneous measurements of the position and momentum of an electron and a proton that are moving along a straight line. An alternate statement of the uncertainty principle involves relationship between position \Delta x) and momentum \Delta p) uncertainties in the form . If both of them are located with an uncertainty of 1 × 10<sup>-10</sup>m, what is the ratio of uncertainty in the velocity of the electron to that of the proton? A) 1.672 B) 1837 C) 9.109 D) 0.177 E) 5.443$ . If both of them are located with an uncertainty of 1 × 10^-10m, what is the ratio of uncertainty in the velocity of the electron to that of the proton?

Definitions:

Posttest Loop

A loop structure that guarantees execution of its block at least once by testing its condition at the end of an iteration instead of at the beginning, typically exemplified by the do-while loop.

Do-while

A control flow statement in programming that executes a block of code at least once and then repeats the loop as long as a specified condition is true.

Actual Parameters

Values that are passed to a function when it is called.

Actual Arguments

The actual values or expressions passed to a function or procedure at the time of call.
