<span>The correct answer is C:Waves transfer energy, but not matter. A wave does not move matter in the direction of its propagation. It only transfers energy just like the ocean wave traveling many miles away with the water just moving up and down.</span>

Conductors, type SIS, for switchboard wiring, have a maximum operating temperature of: _______
Sati [7]

Conductors, type SIS, for switchboard wiring, have a maximum operating temperature of: 194 degree Fahrenheit.

<u>Explanation:</u>

A Panelboard or Switchboard wire is known as SIS.This type of SIS, have tin coating and it is manufactured with a copper conductor insulation.  It is helpful for facilitating solder and also it will be easy to fix them in tighter spaces because for their flexible nature.

As they are insulated with XLPE  they can be used at a voltage operating at 600 V and can be used at a temperature of 194 degree Fahrenheit or 90 degree Celsius. of The XLPE(Cross-Linked Polyethylene) insulation is rated for use at 90°C in either wet or dry locations at an operating voltage of 600 V. They can be used for distribution, panel and switch board wiring.

Water is flowing in a pipe with a varying cross-sectional area, and at all points the water completely fills the pipe. At point
Salsk061 [2.6K]

Answer:

The fluids speed at a) 0.105\,m^{2}  and b) 0.047\,m^{2} are 2.33\,\frac{m}{s^{2}}  and 5.21\,\frac{m}{s^{2}} respectively

c) Th volume of water the pipe discharges is: 882\,m^{3}  

Explanation:

To solve a) and b) we should use flow continuity for ideal fluids:

\Delta Q=0(1)

With Q the flux of water, but Q is Av using this on (1) we have:

A_{2}v_{2}-A_{1}v_{1}=0 (2)

With A the cross sectional areas and v the velocities of the fluid.

a) Here, we use that point 2 has a cross-sectional area equal to A_{2}=0.105\,m^{2}, so now we can solve (2) for v_{2}:

v_{2}=\frac{A_{1}v_{1}}{A_{2}}=\frac{(0.070)(3.5)}{0.105}\approx2.33\,\frac{m}{s^{2}}

b) Here we use point 2 as A_{2}=0.047\,m^{2}:

v_{2}=\frac{A_{1}v_{1}}{A_{2}}=\frac{(0.070)(3.5)}{0.047}\approx5.21\,\frac{m}{s^{2}}

c) Here we need to know that in this case the flow is the volume of water that passes a cross-sectional area per unit time, this is Q=\frac{V}{t}, so we can write:

A_{1}v_{1}=\frac{V}{t}, solving for V:

V=A_{1}v_{1}t=(0.070m^{2})(3.5\frac{m}{s})(3600s)=882\,m^{3}
