Suppose You Have Two Very Sensitive Balances That Can Measure

question 31

Multiple Choice

Suppose you have two very sensitive balances that can measure the masses of individual particles, depicted below. In these figures, "p" corresponds to a proton, and "n" corresponds to a neutron. What is the relationship between the mass readings of the two balances? (Neglect differences due to experimental uncertainty.)

• A) The mass reading of balance 1 will be much higher than the mass reading of balance 2.
• B) The mass reading of balance 1 will be slightly higher than the mass reading of balance 2.
• C) The mass reading of balance 1 will be exactly the same as the mass reading of balance 2.
• D) The mass reading of balance 1 will be slightly lower than the mass reading of balance 2.
• E) The mass reading of balance 1 will be much lower than the mass reading of balance 2.

Definitions:

Linear Association

A relationship between two variables that can be represented on a graph as a straight line, indicating a consistent rate of change.

Moderately Strong Association

A statistical term indicating a reasonably strong relationship between two variables, showing noticeable correlation but not absolute prediction.

Little or No Association

A term used in statistics to describe a situation where there is very weak or no relationship between two variables being studied.

Very Strong Association

A term in statistics indicating a high level of correlation between two variables.
