What does the psychology workforce look like? In July, APA's Center for Workforce Studies (CWS) released a report to address that question. The report paints a picture of demographic trends in the field from 2005 to 2013, using data from the U.S. Census Bureau's annual American Community Survey.
Though the report paints that picture in relatively broad brushstrokes, it provides an important first step toward a more complete understanding of psychology's workforce. Precise workforce data help policymakers, educators and the public understand the range of psychology's impact on society and can help determine the resources necessary to support them, says Ronald Rozensky, PhD, a professor of clinical and health psychology at the University of Florida and a longtime advocate of workforce analysis.
"Accurate workforce data are really important to use when advocating for education, training, scientific funding and reimbursement for practice," he says.
The new report analyzed data from the approximately 83,000 individuals who listed their occupation as "psychologist" and reported having a professional degree (such as an MD, DDS or JD) or doctoral degree (such as a PhD or EdD) in any field. From 2005 to 2013, the supply of active psychologists remained fairly stable, the authors found, with enough new psychologists entering the field to compensate for an increase in the number of retired psychologists over that span.
That workforce was not evenly distributed, however. California, New York and Pennsylvania have the largest numbers of active psychologists. In fact, those three states together account for a third of the workforce. Western and Southern states tended to have the lowest numbers of active psychologists.
As the sphere moves in the liquid, it experiences a viscous force upwards that tries to resist its downward motion caused by gravity(it's own weight). This viscous force gradually increases with depth, as the speed rises(because the weight causes a positive acceleration in it's direction). At a point, the viscous force upwards becomes exactly equal to the weight downwards. Then the sphere reaches equilibrium. It doesn't have any external force acting on it, so it can't have any acceleration. So, it's velocity becomes constant, and this velocity is known as the terminal velocity.
Answer:
Mass, m = 6 kg
Explanation:
Given that,
The momentum of the object, p = 18 kg-m/s
Velocity, v = 3 m/s
We need to find the mass of an object.
The momentum of an object is given by :
p = mv
m is mass of the object
So, the mass of the object is 6 kg.
