Explanation:
The relation between potential difference, current and resistance flowing in a circuit is given by using Ohm's law. It can be given by :
V = IR

Resistance opposes the flow of electric current in the circuit. It means that, if resistance is more, less current will flow through the circuit.
Answer:
M = 500 J
Explanation:
Given that,
Mass, M = 1000 g = 1 kg
Height, h = 10 m
Potential energy is given by :
P = mgh
P = 1×10×10
P = 100 J
The kinetic energy at ground = 400 J
Mechanical energy = sum of kinetic and potential energy
So,
M = 100 + 400
M = 500 J
So, the mechanical energy of the system is 500 J.
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>
Explanation:
A wave having a frequency of 200 Hz means that 200 such waves pass through a point per second.
Answer:
Illusory correlation
Explanation:
Illusory correlation is a psychological phenomenon of sensing a correlation or relationship between a particular quantity and other variables however unrelated the two variables may be. A person may establish such connections, which are indeed false connections, as a result of over emphasis on novel incidents that are easily noticed due to them being salient
For example, when a waiter at a restaurant is being rude to a person after the person was made to walk under a ladder due to ongoing construction.
