Which switch configuration creates a short circuit?
lara31 [8.8K]
I think the answer would be Switch 1 open; switches 2, 3, and 4 closed. It is letter D. This will happen when there is a low resistance and a high circuit so from the choices above, when two bulbs are open and one bulb is close, so there is a low resistance and high voltage.

As the wave interacts with a wall, which kind of wave interaction is shown?
kow [346]
 The answer would be a reflection. This is because, t<span>he color of an object is actually the wavelengths of the light reflected while all other wavelengths are absorbed. Color, in this case, refers to the different wavelengths of light in the </span>visible light spectrum<span>perceived by our eyes. The physical and chemical composition of matter determines which wavelength (or color) is reflected.</span>

High voltage power is often carried in wire bundles made up of individual strands. In your initial post to the discussion, discu
Firdavs [7]

Answer:

<em>There will  be a huge problem of holding the wire strands together, and the power losses will also be amplified.</em>

Explanation:

The force per unit length on two current carrying conductors, lying parallel to each other is proportional to the product of the current through the conductors, and inversely proportional to their distance apart. This force is attractive if the current flows through these conductors in the same direction, and is repulsive if it flows in the opposite direction.

For the strand of wire that make up a high voltage wire bundle, there will be a force of attraction pulling the wires closer to each other, and they will experience the maximum pulling force possible, since they lie next to each other. This force helps to hold these wires in a high tension wire strand together, limiting the area, and reducing "skin effect."

In the case that this wires in the wire strand acts in opposite of the known behavior, the wires will repel and push each other apart. This pushing apart will increase power loss due "skin effect" which is increased by an increase in exposed surface area of the wire strands. This will pose a big problem for high tension transmission.

Two students measure the time constant of an RC circuit. The first student charges the capacitor using a 12 V battery, then lets
luda_lava [24]

Answer:

The answer is: c.) Both students get the same time constant, since the time constant does not depend on the charge on the capacitor

Explanation:

Both students, because the time constant is not dependent on the capacitor charge.  We can express the equation of the time constant as follows:

Time constant = RC

In this equation it is observed that the time constant is equal to the multiplication of the resistance (R) multiplied by the capacitance (C)

Two sinusoidal waves traveling in opposite directions interfere to produce a standing wave with the wave function y = (2.00) sin
olga2289 [7]

Answer:

Part a)

\lambda = 4\pi

Part b)

f = 47.7 Hz

Part c)

v = 600 m/s

Explanation:

Part a)

As we know that angular wave number is given as

k = \frac{2\pi}{\lambda}

k = 0.500

0.500 = \frac{2\pi}{\lambda}

\lambda = \frac{2\pi}{0.500}

\lambda = 4\pi

Part b)

As we know that angular frequency is given as

\omega = 300 rad/s

\omega = 2\pi f

300 = 2\pi f

f = \frac{300}{2\pi}

f = 47.7 Hz

Part c)

Speed of the wave is given as

v = \lambda \times frequency

so we have

v = 4\pi \times 47.7

v = 600 m/s
