According to a general theory of crime, individuals who engage in crime are also likely to engage in other risky behaviors, for
babymother [125]

Answer:

construct validity

Explanation:

According to my research on studies conducted by various psychologists, I can say that based on the information provided within the question it seems that the researcher is using construct validity. This is the act of measuring or validating what the extent to which a claim is true. In this situation since the claim states that people involved in crimes tend to do speed and drugs, then the researcher compares the criminals responses to those areas to test the validity of the claim.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

A constant force of 45 N directed at angle θ to the horizontal pulls a crate of weight 100 N from one end of a room to another a
Rasek [7]

Answer:

W=173.48J

Explanation:

information we know:

Total force: F=45N

Weight: w=100N

distance: 4m

vertical component of the force: F_{y}=12N

-------------

In this case we need the formulas to calculate the components of the force (because to calculate the work we need the horizontal component of the force).

horizontal component: F_{x}=Fcos\theta

vertical component: F_{y}=Fsen\theta

but from the given information we know that F_{y}=12N

so, equation these two F_{y}=Fsen\theta and F_{y}=12N

Fsen\theta =12N

and we know the force F=45N, thus:

45sen\theta=12

now we clear for \theta

sen\theta =12/45\\\theta=sin^{-1}(12/45)\\\theta =15.466

the angle to the horizontal is 15.466°, with this information we can calculate the horizontal component of the force:

F_{x}=Fcos\theta

F_{x}=45cos(15.466)\\F_{x}=43.37N

whith this horizontal component we calculate the work to move the crate a distance of 4 m:

W=F_{x}*D\\W=(43.37N)(4m)\\W=173.48J

the work done is W=173.48J
