Answer:
IT and science courses
Explanation:
As Health Information Management department requires a person who should have fair knowledge about science and medical so that he/she can deal with the data extracted from diseases. He/she should also have fair knowledge about IT so that the person can manage the files and data very well. The data should be managed accurately so different IT programs help in completing this goal. IT knowledge will help to keep data safe, accurate and complete. Due to IT knowledge they can upgrade and redesign programs according to their need.
Explanation:
It is given that,
Mass of the box, m = 10 kg
Force with which the box is pulled, F = 50 N
It is moved a distance of 4 m
Force of friction acting on the box, f = 20 N
We need to find the initial kinetic energy the box have. It is clear that the box is at rest initially. As there is no motion in the box at that time. The formula for the kinetic energy of the box is given by :
As v = 0
So, the initial kinetic energy of the box is 0. Hence, this is the required solution.
Effort force and Resistance force
Because the box keeps going straight at the same speed, while the seat under it speeds up, slows down, or changes direction.
