Assuming the surface on which the box moves is frictionless, the rate at which the box accelerate is equal to 0.5 
.
<u>Given the following data:</u>
- Mass of box = 50 kilogram
To determine the rate at which the box accelerate, assuming the surface on which the box moves is frictionless:
Mathematically, Newton's Second Law of Motion is given by the formula;
Making acceleration the subject of formula, we have:
Substituting the given parameters into the formula, we have;
Acceleration = 0.5

Answer:
The main function of the immune system is to provide immunity to the body. Immunity is the body's ability to protect itself from the pathogens it is exposed to. Immunity depends on the body's ability to differentiate between things that belong in the body and those that do not. The immune system's first line of defense includes physical and chemical barriers that are always ready and prepared to defend the body from infection.
The skin acts as a barrier against pathogens. Some structures of the first line of defense include the skin, mouth, eyes, ears, nose, and stomach. The skin produces sweat and oil that work together to keep pathogens from the entering the body. Saliva and tears contain substances the can destroy pathogens. The ears and the stomach help fight pathogens.The ears produce ear wax that prevent pathogens from entering the ears. The stomach produces a liquid the kills pathogens.
Mucus is produce by the nose, lungs, throat, and stomach. Mucus traps pathogens. Mucus also prevent pathogens from getting into deep tissues. Anyway, the very first line of defense against any invasion of the human body is a set of physical barriers between the inside of the body and the outer world.
