14.7lb/in²
Explanation:
This is a conversion problem from atm to pounds per square inch
Pressure is the combined force per unit area of substance on another.
Given pressure = 0.5atm
To solve this problem ;
Convert from atm to N/m² to pound per square inch
1 atm = 101325N/m²
0.5atm = 0.5 x 101325 = 50,662.5N/m²
now we need to convert to pound per square inch;
1N = 0.225lb
1m = 39.37in
Solving;
101325 N
= 14.7lb/in²

We can perceive this question as a vector (which has both magnitude and direction). The magnitude is the displacement and the direction is where they are headed.
Explanation:
The displacement (magnitude of the vector) for Callie, which is also equal to the distance, is; 4m + 3m = 7m while that of Sue is 5m. Therefore the displacement for Callie is greater than Sue’s.
Nonetheless the direction in the vector is the same, which is towards point C.
