Answer:
(C) zero (there is no net horizontal component of the E-field)
Explanation:
If we subdivide the bar into small pieces, each piece (dx) contains a charge (dq), the electric field of each piece is equivalent to the field of a punctual electric charge, and has a direction as shown in the attached figure. For each piece (dx) in the negative axis there is another symmetric piece (dx) in the positive axis, and as we see in the figure for symmetry the sum of their electric fields gives a resultant in the Y axis (because its components in X are cancelled by symmetry).
Then the resultant of the electric field will be only in Y.
(C) zero (there is no net horizontal component of the E-field)
Answer:
The correct answer is Cognitive.
Explanation:
The psychologist Leon Festinger proposed the theory of cognitive dissonance, which explains how people try to maintain their internal consistency. He suggested that individuals have a strong inner need that pushes them to ensure that their beliefs, attitudes and behavior are consistent with each other. When there is inconsistency between them, the conflict leads to a lack of harmony, something that people strive to avoid.
This theory has been widely studied in the field of psychology and can be defined as the discomfort, tension or anxiety that individuals experience when their beliefs or attitudes conflict with what they do. This displeasure can lead to an attempt to change behavior or defend their beliefs or attitudes (even reaching self-deception) to reduce the discomfort they produce.
Full Question:
What is the temperature of a system in thermal equilibrium with another system made up of water and steam at one atmosphere of pressure?
A) 0°F
B) 273 K
C) 0 K
D) 100°C
E) 273°C
Answer:
The correction Option is D) 100°C
Explanation:
The temperature above is referred to as the critical point.
it is the highest temperature and pressure at which water (which has three phases - liquid, solid, and gas) can exist in vapor/liquid equilibrium. If the temperature goes higher than 100 degrees celsius, it cannot remain is liquid form regardless of what the pressure is at that point.
There is also a condition under which water can exist in its three forms: that is
- Ice (solid)
- Liquid (fluid)
- Gas (vapor)
That state is called <em>triple point. </em>The conditions necessary for that to occur are:
- 273.1600 K (0.0100 °C; 32.0180 °F) as temperature and
- 611.657 pascals (6.11657 mbar; 0.00603659 atm) as pressure

I think it would'nt move at all but im not postive
<span>The same amount of pressure is exerted on all sides of the object equally.
If you had 13 psi, then that means on the top of the object, 13 psi would be pushing in on the object. From the bottom, 13 psi would be pushing up on the object.
Same goes for all the sides as well. The pressure pushes 'in' on the object.</span>
