Final answer:
The air pressure of a rocket launch tube with an inside launch force of 40 N applied over an area of 2.5 square meters is 16 N/m².
Step-by-step explanation:
To calculate the air pressure of a rocket launch tube, you can use the formula for pressure, which is the force applied per unit area. In this case, we are given a launch force of 40 N being exerted over an area of 2.5 square meters. The formula to calculate pressure (P) is P = F/A, where F is the force in newtons and A is the area in square meters.
Given:
Force (F) = 40 N
Area (A) = 2.5 m²
Using the formula:
P = F / A
P = 40 N / 2.5 m²
P = 16 N/m²
So, the air pressure in the rocket launch tube is 16 N/m², which corresponds to option A.
