The slope of a position/time graph is the speed of the motion.
(The slope doesn't 'determine' the speed; it only displays it.)
The slope of a speed/time graph is the acceleration of the motion.

I world say A is the answer 80% sure
What exactly is a psychological disorder? How is a psychological disorder diagnosed? Defining exactly what constitutes a mental disorder can be tricky and, definitions have changed over time.
The
first problem is that psychologists must first decide exactly how to
define disorder. How do you determine if there is something
psychologically wrong or unhealthy about a person? How do you decide
what's normal and what's abnormal?
If you were to define disorder
as something that lies outside of the statistical norm, then people who
are considered exceptionally talented or gifted in a particular area
would be regarded as abnormal. So rather than focus on actions that are
considered outside of the normal statistically speaking, psychologists
tend to concentrate on the results of those behaviors. Behaviors that
are considered maladaptive and cause significant personal distress and
interrupt daily functioning are more likely to be labeled as abnormal.
Today
many psychologists agree that psychological disorders are characterized
by both personal distress and impairment in multiple areas of life.
Answer:
2.2nC
Explanation:
Call the amount by which the spring’s unstretched length L,
the amount it stretches while hanging x1
and the amount it stretches while on the table x2.
Combining Hooke’s law with Newton’s second law, given that the stretched spring is not accelerating,
we have mg−kx1 =0, or k = mg /x1 , where k is the spring constant. On the other hand,
applying Coulomb’s law to the second part tells us ke q2/ (L+x2)2 − kx2 = 0 or q2 = kx2(L+x2)2/ke,
where ke is the Coulomb constant. Combining these,
we get q = √(mgx2(L+x2)²/x1ke =2.2nC
I believe the percentage is between 15-20%. Stress is a well known factor that affects the performance of people.
