So, when two different air masses meet, a boundary is formed. The boundary between two air masses is called a front. Weather at a front is usually cloudy and stormy. There are four different fronts- Cold, Warm, Stationary, and Occluded.
Answer:
3.63m/s²
Explanation:
Given parameters:
Mass of box = 8kg
Net force = 29N
Unknown:
Acceleration of the box = ?
Solution:
To solve this problem, we use Newton's second law of motion which is stated as;
Force = mass x acceleration
Acceleration = 
= 
Acceleration = 3.63m/s²
