Answer:
many unknown variables that directly affect the individual's heart health condition.
Explanation:
The problem with this conclusion is that there are many unknown variables that directly affect the individual's heart health condition. Their socioeconomic status is one such variable since this determines whether or not the individual is able to afford the right types of food, healthcare, medicine, etc. All of these are vital components of maintaining a healthy heart and preventing heart disease. Ancestral health histories are also an important variable to take into consideration in this scenario but it was not. Therefore, the data gathered is not very reliable.
Answer:
(3) TIR causes a portion of the light to be refracted and the rest to be reflected
Explanation:
Total internal reflection is the reflection of a light ray completely within a medium for example glass or water which bounces back after reflecting from the surrounding surfaces into the medium. When the incident angle is more than an certain limiting angle, called the critical angle, the phenomenon is called total internal reflection.
In total internal reflection none of the portion of the incident light gets refracted, it gets only reflected multiple times within the medium.
Hence the false statement is (3).
