Answer:
electric flux is 280 Nm²/C
so correct option is D 280 Nm²/C
Explanation:
radius r = 0.50 m
angle = 30 degree
field strength = 713 N/C
to find out
the electric flux through the surface
solution
we find here electric flux by given formula that is
electric flux = field strength × area× cos∅ .......1
here area = πr² = π(0.50)²
put here all value in equation 1
electric flux = field strength × area× cos∅
electric flux = 713 × π(0.50)² × cos60
we consider the cosine of the angle between the direction of the field and the normal to the surface of the disk
so we use cos60
electric flux = 280 Nm²/C
so correct option is D 280 Nm²/C
Kepler was the one who during the Renaissance, came up with the theory of elliptical planetary orbits around the sun. Up to that time the planetary orbits were assumed to be circular. By using the observations and data of Tycho Brahe, and also using both mathematical and physical (relative to the properties of matter) proofs, he thus used the scientific method to determine the type of orbits. In other words, he used the model that Brahe had worked out and then developed that model into an accurate appraisal of the orbits. This is the scientific method, starting with what is known and doing investigation into what is unknown by studying the material world and basing one's expanded thinking on the new facts unearthed in the process. In the modern world we all use this method, from figuring out why a vacuum cleaner is not functioning to the theory of plate tectonics.
I hope this helped!
Because they're quadcopters
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.
Answer:
initial velocity (u) = 200m/s
final velocity (v) = 350 m/s
time (t) = 15s
acceleration (a) = ?
NOW,
a=v-u/t
a= 350-200/15
a= 50/15
a= 3.3333
Explanation:
it's too easy just u need to understand the question . and go according to it's content .
main thing to memorize is it's simple formula.
