Answer:

D. The General Adaptation Syndrome

Explanation:

Hans Selye, an endocrinologist, developed the <em>"Stress Theory."</em> He showed the relationship of <em>"stress"</em> to the person's development of disease.

Under stress, <em>a person's body experiences changes</em>. The person tries to cope with these through three stages: <em>Alarm Reaction Stage, Resistance Stage and Exhaustion Stage. </em>It is at the<em> last stage</em> that a person's immune system is placed at a huge risk. Once the person is exposed to a stressor for a period of time, he becomes hopeless and his body tends to give up coping. He then succumbs to <em>stress-related illness.</em>

An atom with the expected number of neutrons, protons, and electrons is called a(n)
ryzh [129]

Answer:

Stable atom

Explanation:

A stable atom is one that has a balanced nuclear inter-particle force reaction as such the binding energy of a stable atom is sufficient to permanently keep the nucleus as one unit. Examples of a stable atom are the atoms of  monoisotopic elements such as fluorine, sodium, iodine, gold, aluminium, and cobalt.

In a stable atom the expected number of proton, neutron, and electron are present while in an unstable atom or radioactive atom, there are more than the expected number of neutrons or protons, such that the internal energy of the nucleus is excessive and more than the binding energy, which can lead to radioactive decay.

A girl of mass 55 kg throws a ball of mass 0.80 kg against a wall. The ball strikes the wall horizontally with a speed of 25 m/s
lisabon 2012 [21]

Answer:

Magnitude of the average force exerted on the wall by the ball is 800N

Explanation:

Given

Contact Time = t = 0.05 seconds

Mass (of ball) = 0.80kg

Initial Velocity = u = 25m/s

Final Velocity = 25m/s

Magnitude of the average force exerted on the wall by the ball is given by;

F = ma

Where m = 0.8kg

a = Average Acceleration

a = (u + v)/t

a = (25 + 25)/0.05

a = 50/0.05

a = 1000m/s²

Average Force = Mass * Average Acceleration

Average Force = 0.8kg * 1000m/s²

Average Force = 800kgm/s²

Average Force = 800N

Hence, the magnitude of the average force exerted on the wall by the ball is 800N
