Which of these statements accurately captures a current trend in operations? A. There is increased focus on local market and lo

Flura [38]

Answer:

Option B

Explanation:

The current trend in operations is accurately captured by Rapid Product Development.

This concept in an organization describes a process in development which is quite fast and progressive.

To achieve rapid Product Development, a combination of integration of various innovative and creative prototyping techniques including latest Computer supportive operative tools, i.e., CSCW are used.

These tools are incorporated into the process of Research and Development in an organization in order to develop products by optimization of quality, price and time.

Which occurs when two or more waves combine to produce a wave with a larger displacement?

Dimas [21]

When two or more waves combine to produce a new wave, that's 'interference'.

-- If the new wave has larger displacements (amplitude), then it's CONstructive interference.

-- If the new wave has smaller displacements (amplitude), then it's DEstructive interference.

In medieval warfare, one of the greatest technological advancement was the trebuchet. The trebuchet was used to sling rocks into

NNADVOKAT [17]

Answer:

2) a_y= -g 3) vₓ=constant v_y = v_{oy} - g t, 4) vₓ = v₀ₓ - ax t

5) changes the horizontal speed, should change range

7) changes the vertical speed change the maximum height

Explanation:

1) After reading your long writing, we are going to solve the exercise, in the attachment you can see the different vectors.

2) The acceleration vectors are vertical and directed downwards due to the attraction of the Earth (gravity force) this force is constant, on the x axis there is no acceleration

3) the velocity vectors on the x-axis are constant because there are no relationships and the y-axis changes value according to the expression

v_y = v_{oy} - gt

at the point of maximum height, vy = 0 is equal to the maximum height

4) For someone to change the horizontal acceleration we must assume a friction with the air, in this case they relate it would be in the opposite direction to the horizontal speed

In the graph it would be directed to the left, therefore the velocity would be

vₓ = v₀ₓ - ax t

5 and 6) If someone changes the horizontal speed, they should change the range of the shot for greater horizontal speed, the rock goes further.

the equations of motion are

x = v₀ₓ t

y = v_{oy} t - ½ g t²

7) If someone changes the vertical speed change the maximum height, but not the scope of the shot, for higher speed higher maximum height,

the equations of motion are the same.

The advantages and disadvantages of using copper, steel and aluminium in electrical cables.

katrin [286]

Advantages of copper cables are that copper is an extremely powerful conductor of electricity and much more stable over time. It can withstand higher temperatures than aluminum and is more resistant to damage. Disadvantages: Copper is more expensive and heavier and thus requires structural support. Advantages of aluminum cables are that it is less expensive, easier to work with and light weight and so does not need structural support when strung over long distance. Disadvantages: Aluminum is more susceptible to corrosion and requires periodic replacement. It needs much greater maintenance. Advantages of steel cables are that steel does not rust, is fairly cheap and readily available. It has a higher tensile strength too. Disadvantages: Steel cables are less ductile and are therefore more susceptible to fatigue.

Why does a glass rod become positively charged when it is rubbed with a silk cloth?

slavikrds [6]

The core has positive charge, the electrons have negative charge. When you are rubbing the glass rod with the silk cloth, electrons are stripped away from the atoms in the glass and transferred to the silk cloth. This leaves the glass rod with more positive than negative charge, so you get a net positive charge.
