Researchers with a positivist philosophy believe that by being objective and unbiased they can see reality clearly, while researchers with a post positivist philosophy believe that they can only achieve inter subjective agreement about the nature of reality.
<u>Explanation:</u>
The researcher who believe on the philosophy of positivism have a clear sense of seeing facts. They believe that these facts are empirical evidence. They believe that it is the law that exists in general according to which the society is acting accordingly.

Glide describes going down smoothly
At 30 mph the tires may lose all contact with the road when there is standing water; if this occurs, there is no friction available to brake, accelerate, or steer.
Try to stay on the highest part of the road while it is raining heavily. Starting at roughly 35 mph, wet road conditions can cause tires to hydroplane or ride up on a film of water, which could result in a driver losing control of his or her car. Starting at roughly 35 mph, wet road conditions can cause tires to hydroplane or ride up on a film of water, which could result in a driver losing control of his or her car. As speed rises, the likelihood of hydroplaning increases. Tires may completely separate from the road surface after 55 mph.
