5 0

Answer:

The given statement is TRUE

Explanation:

Friction is a force experienced by a body that resists its motion.

In other words, Friction is the force experienced by the two bodies (with uneven or rough surfaces) when moving against each other.

When an object slides on a surface, the surface area of the object in contact with the surface is more as compared to an object which is rolled on the surface. Therefore, the friction force experienced by the sliding body is greater than the rolling body.

Therefore, we can say that the rolling friction is less than the sliding friction.

Evaluation of evidence should be solely based upon study design.<br> A. True<br> B. False
ki77a [65]

Answer:

The correct answer to this question: Evaluation of evidence should be based solely upon study design:____, would be: false.

Explanation:

According to research done on the topic, there are many other issues that must be taken into account when evaluating the results of a research study, be it clinical, or in the field, and not simply study design. Study design allows the evaluators to assess the style, the form, and the way in which the study was carried out to reach results, but evaluating results, the evidence gathered only based on how the study was designed would be wrong. This evidence evaluation should focus primarily on how the intervention worked on a certain  study, and whether it was carried out in such a way that would yield the proper results, without bias.
