The answer you are looking for is chitin.
According to a page that I found with info on the subject,
"All arthropods have bodies divided into segments and covered with a hard EXOSKELETON. This tough casing is made of a protein called chitin, which is also found in human fingernails."

Answer: The correct answer is D) One substance can be separated from another through physical means.
Mixture is a combination of two or more substances that are combined or mixed physically in a way that they do not loose their identity.
This means that mixture does not undergo any chemical change and it can be separated through physical means (like filtration). It can be of solid, liquid, or gaseous molecules.
Mixture can be primarily divided into homogenous ( having uniform composition that is every sample will have same property) and heterogenous mixture ( non uniform composition that is not every sample will have same property).
Thus, option D) is a property of every mixture.
sensory and motor areas undergo major growth spurts during middle childhood.
- The two types of motor (movement) skills that children acquire are called "fine motor skills" and "gross motor skills."
- Using hands and fingers to control smaller things is a function of fine motor abilities. coordination is a component of gross motor skills.
- Synaptic remodeling, or pruning, is a natural process of maturation. Additionally, because each child has a different experience, the brain grows in large part as a result.
- More often utilized synapses tend to be kept, whereas less frequently used synapses are lost.
- The brain is driven by the motor system, which also drives sensory stimulation and feedback.
- These abilities must advance and grow in order to support behavior and academic learning.
- Children that struggle academically or behaviorally frequently have underdeveloped sensory and motor systems.

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
