A sigma-plus (Σ+) particle and an unidentified particle Y are produced by the strong interaction between a positive pion (π+) and a proton (p). 
 
This interaction is represented by the equation: 
 
π+ + p → Σ+ + Y

TX PACT: Essential Academic Skills 700 (Subtest III: Mathematics - 703) (2022/2023) (Passed with 100%) Real numbers are numbers that have a specific value. Real numbers can be rational or irrational. Within rational numbers, there are integer, whole, and natural numbers. 
Rational numbers are numbers that can be expressed as a ratio (fraction or comparison) of two integers, a/b where b ≠ 0 (because zero can't be the denominator of a fraction). All rational numbers can be written exactly in bo...
