Improving quality of a product can lead to a lower cost since if products are faulty, the customers will return which is sometimes need to be replace thus it would be a profit loss but if it is of good quality this can be avoided. Another would be if there is no warranty in the shop it can damage the reputation causing them to lost customers and can also result to lawsuits. If there is good quality then these can't be happening.
As plasma membrane is semipermeable membrane which allow materials to move across it in both direction. Semi permeable is the reason
I’m assuming the cannon ball is being shot directly horizontally. If there’s an angle, this answer will be wrong. But either way, you want to use Newton’s Second Law of motion.
F = ma, you could change this to a = F/m to get a better understanding of the equation. Acceleration and force are directly proportional. The mass is inversely proportional to acceleration. This means the net force will be in the same direction as the acceleration.
Alright back to the problem:
F = 4kg*110m/s^2
F = 440N
