In the conflict resolution, promotes competition a win-lose outcome. Competition results into conflict when two parties tend to seek control over a situation.
What is Competition in conflict management?Competition results when one's own needs are advocated over the needs and requirements of others. It relies on an aggressive style of communication, which is of low regard for future relationships, and the exercise of coercive power. Those who are using a competitive style tend to seek control over a situation, in both the substance and ground rules.
There are times, when competition between two individuals can escalate into an unproductive, and dangerous conflict. The danger can range from unproductive behavior of a person to unethical behavior which could include physical attack. This results into a win-lose outcome.

what does "no reference to direction of motion mean"?
Explanation:
its means the quantity in question is a scalar quantity, has only magnitude but no direction, for example. speed,has no reference to direction of motion, since the speed of a body say 5 m/s( the direction of the body has not been stated) but the velocity of a body say 5m/s to the east has a reference to direction of the motion.
That's why velocity is different from speed

. Which of the following explains how water undergoes a change of state in one stage
of the water cycle in order to move from the ocean's surface into the air?
Answer: F
Explanation:
At one stage of water cycle, liquid water is heated by the sun and gets converted to the gaseous state and rises to the air. Hence, option A is correct.
What is water cycle?Water cycle is a geological phenomenon of balancing the water content in the atmosphere, hydrosphere and biosphere. The heat radiated from the sun warm up water in the water bodies.
The convection current in water make the whole water warmer and converts it to the vapor phase. The water vapor rises above the surface and reset the water level in the atmosphere.
The water level in hydrosphere is again restore by the rain. This process continues cyclically to balance the water content in all layers. Therefore, option a describes the stage of water cycle which move water from oceans.

Answer:
I = 1.09 A
Explanation:
Here, 5 ohm and 12 ohm resistor are connected in parallel. Using the parallel combination of resistors as follows :
[tex]\dfrac{1}{R}=\dfrac{1}{R_1}+\dfrac{1}{R_2}\\\\\dfrac{1}{R}=\dfrac{1}{5}+\dfrac{1}{12}\\\\ R=3.52\ \Omega[/tex]
Now R and 2 ohm resistors are in series. Let the equivalent be [tex]R_{eq}[/tex]. So,
[tex]R_{eq}=3.52+2\\\\=5.52\ \Omega[/tex]
Let I be the current. Using Ohm's law,
V = IR
[tex]I=\dfrac{V}{R_{eq}}\\\\I=\dfrac{6}{5.52}\\\\I=1.086\ A[/tex]
or
I = 1.09 A
So, the correct option is (c).
2-The amount of internal energy needed to raise the temperature of 0.25kg of water by 0.2°C is 209.3 J. How fast must a 0.25 kg baseball travel in order for its kinetic energy to equal this internal energy?
Answer:
40.92 m/s
Explanation:
The computation is shown below:
Ek = 1 ÷2mv²...............................(1)
v = √(2Ek/m).......................... (2)
Here EK denotes kinetic energy
m denotes mass
v denotes velocity
Given that
m = 0.25kg and Ek = 209.3J

Remark
The only thing that might trip you up is what to do with the angle. The vertical component of the 15 degrees does no work against anything. So the 15 degrees limits the horizontal force.
The formula is
Work = F * d * cos(15)
The givens are
F = 2000 N
d = 30 m
Cos(15) = 0.9659
Solution
Work = 2000 * 30 * cos(15)
Work = 57,955
Rounded to two places would be 5.8 * 10^4

Migratory birds use Earth’s magnetic field to guide them. Some people are concerned that human-caused magnetic fields could interfere with bird navigation. Suppose that a pair of parallel high-voltage lines, each carrying a current of 100A are 3.00 meters apart and lie in the same horizontal plane. Find the magnitude and direction of the magnetic field the lines produce at a point 15.0 m above the midpoint between the two lines in each of these two cases:
Solution :
The direction of current is into the page.
The magnetic field [tex]$B_1$[/tex] due to the wire is perpendicular to AP and the magnetic field [tex]$B_2$[/tex] due to the wire is perpendicular to BP. Thus, the net magnetic field at point P is towards the right.
The net magnetic field at point P is
[tex]$B_{net} = B_1 \cos \theta + B_2 \cos \theta$[/tex]
The magnetic field is
[tex]$B_1=B_2=\frac{\mu_0I}{2 \pi L}$[/tex]
The angle θ is
[tex]$\theta = \cos^{-1}\frac{h}{L}$[/tex]
The net magnetic field at point P is
[tex]$B_{net}=\left(\frac{\mu_0I}{2 \pi L}\right)\left(\frac{h}{L}\right)+\left(\frac{\mu_0I}{2 \pi L}\right)\left(\frac{h}{L}\right)$[/tex]
[tex]$=\frac{\mu_0 Ih}{\pi L^2}$[/tex]
a). The direction of the current for both the wires is from north to south. The net magnetic field is towards the right when we are facing south.
[tex]$B_{net}=\frac{\mu_0 Ih}{\pi L^2}$[/tex]
[tex]$=\frac{\mu_0I L}{\pi \left(\sqrt{h^2+(d/2)^2\right)^2}}$[/tex]
[tex]$=\frac{4 \pi \times 10^{-7} \times 100 \times 15}{\pi \left(\sqrt{15^2+(3/2)^2\right)^2}}$[/tex]
[tex]$=2.64 \times 10^{-6} \ T$[/tex]
The direction is towards the west.
b). Since, both the magnetic field are equal and opposite, so no magnetic field is produced.

Two speakers that are 15.0 mproduce in-phase sound waves of frequency 250.Hz in a roomwhere the speed of sound is 340. m/s. A woman starts out at the midpoint between the two speakers.a.What does she hear at the midpoint, constructive or destructive interference?b.She now walks slowly towards one of the speakers. How far from the center must she walk before she first hears the sound reach a minimum intensity?c.How far from the center must she walk before she first hears the sound at a maximum intensity?d.How far from the center must she walk before the second time she hears the sound at the minimum intensity?
Answer:
a. Constructive interference.
b. [tex]0.34\; \rm m[/tex].
c. [tex]0.68\; \rm m[/tex].
d. [tex]1.02\; \rm m[/tex].
Explanation:
Frequency of this sound wave: [tex]f = 250\; \rm Hz = 250\; \rm s^{-1}[/tex].
Speed of this sound wave: [tex]v = 340\; \rm m \cdot s^{-1}[/tex].
Calculate the wavelength of this sound wave:
[tex]\begin{aligned} \lambda &= \frac{v}{f} \\ &= \fraac{340\; \rm m \cdot s^{-1}}{250\; \rms^{-1}} \approx 1.36\; \rm m\end{aligned}[/tex].
Path difference refers to the absolute value of the difference between:
the distance between the first source (the first speaker) and the observer, andthe distance between the second source (the second speaker) and the observer.When the observer in this question is on the line between the two speakers at [tex]d[/tex] meters from the midpoint, the corresponding path difference would be [tex]2\; d[/tex] meters. (Add [tex]d\![/tex] to the distance from the closer source, and subtract [tex]d\!\![/tex] from the distance from the other source.)
The question states that sound from the two speakers are in-phase. In other words, at every instant, the sound wave from the two speakers are at the same phase at the position of each speaker.
Because wave from the two sources are in-phase at the source:
Constructive interference happens when the path difference is an integer multiple of wavelength ([tex]k\, \lambda[/tex], where [tex]k[/tex] is an integer.) That includes: [tex]0[/tex], [tex]\lambda[/tex], [tex]2\, \lambda[/tex], etc.Destructive interference happens when the path difference is an one-half plus some integer multiple of wavelength ([tex](k + 1/2) \, \lambda[/tex], where [tex]k[/tex] is an integer.) That includes: [tex]\lambda / 2[/tex], [tex]3\, \lambda / 2[/tex], [tex]5\, \lambda / 2[/tex], etc.Path difference is [tex]0[/tex] when the observer is at the midpoint. That would correspond to constructive interference.
The first destructive interference (minimum intensity) corresponds to a path difference of [tex]\lambda / 2[/tex]. Along the line, that would be observed at [tex](1/2) \cdot (\lambda / 2) = 0.34\; \rm m[/tex] from the midpoint.
The next constructive interference (maximum intensity) would be observed when path difference is [tex]\lambda[/tex]. Along the line, that would be observed at [tex](1/2)\cdot \lambda = 0.68\; \rm m[/tex] from the midpoint.
The second destructive interference (minimum intensity) would be observed when path difference is [tex](1 + (1/2))\, \lambda[/tex]. Along the line, that would be observed at [tex](1/2) \cdot ((3/2)\cdot \lambda) = 1.02\; \rm m[/tex] from the midpoint.
