Which law might require you to do some math calculations?
Vadim26 [7]

Answer:

Law 2

Explanation:

Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.

Mathematically, it is given by the formula;

Force = mass * acceleration

Hence, Law 2 might require you to do some math calculations.

For example, an object having a mass of 20kg is pushed by John and it then accelerates down the inclined plane at a rate of 0.5m/s². Find the force applied on the object.

Given the following data;

Mass = 20kg

Acceleration = 0.5m/s²

To find the force;

Force = mass * acceleration

Substituting into the equation, we have;

Force = 20 * 0.5

Force = 10 Newton.

Hi. This question requires a personal answer based on your assessment of your own abilities and qualities. However, I will provide an answer below and hope it serves as a model for you to be able to formulate your own answer.

One of my main characteristics that will be very useful in my work environment is patience. I believe that the medical field requires a lot of patience, as work environments can be very stressful, mainly because you have to deal with the most different types of people. My patience will allow me to work efficiently under pressure and will allow me to deal with the human being without affecting my work. Besides patience, I'm a very agile person. Medical work requires agility, especially when it is related to emergency care, where agility is essential for the patient's health.
