Correlational studies do not form the  decision making or discussion because they do not offer conclusive evidence.

<h3>What are correlational findings?</h3>

The term correlational findings refers to research findings that only show the association between variables. This is a kind of research that does not establish causation but suggests a strong link between two variables.

This kind of study should not form the basis for decision making or discussion because they do not offer conclusive evidence about an issue. this kind of findings should e taken with a pinch of salt until the data is further confirmed by experimental studies.

A 62 pound box is on an incline. Determine the minimum force P that would result in the box starting to slide up the incline. (i
Anon25 [30]

Answer:

F > W * sin(α)

Explanation:

The force needed for the box to start sliding up depends on the incline (α).

The external forces acting on the box would be the weight, the normal reaction and the lifting force that is applied to make it slide up.

These forces can be decomposed on their normal and tangential (to the slide plane) components.

The weight will be split into

Wn = W * cos(α) (in normal direction)

Wt = W * sin(α) (in tangential direction)

The normal reaction will be alligned with the normal axis, and will be equal to -Wn

N = -W* cos(α) (in normal direction)

To mke the box slide up, a force must be applied, that is opposite to the tangential component of the weight and at least a little larger

F > |-W * sin(α)| (in tangential direction)

1. The gravitational force acting on a falling body and its weight is constant. But the law of universal gravitation tells us th
vagabundo [1.1K]
It's not so much a "contradiction" as an approximation. Newton's law of gravitation is an inverse square law whose range is large. It keeps people on the ground, and it keeps satellites in orbit and that's some thousands of km. The force on someone on the ground - their weight - is probably a lot larger than the centripetal force keeping a satellite in orbit (though I've not actually done a calculation to totally verify this). The distance a falling body - a coin, say - travels is very small, and over such a small distance gravity is assumed/approximated to be constant.

8090 [49]

The correct answer is B; Deliberate deception

Further Explanation:

Deception is one when a person is fully aware of what they are doing. They are hiding the truth and making a conscious decision to tell someone something that has no truth. Deception can also be used when describing a magic trick such as a sleight of hand.

Lie scales are used when there are redundant questions that ask the same questions over and over with different formats to see if the answers are consistent over time.
