Answer:

Open circuited

Explanation:

On moving a coil of conductor in a magnetic field a voltage is induced through the conductor, this is called Law of Electromagnetic induction.

As the moving coil will induce some voltage in the conductor, but the current through it will be zero unless we do not connect it with a load to complete the circuit.

As in a open circuit, the amount of current flow is zero.

Also, the voltage is zero in a short circuit.

So, the current in the conductor will be zero unless we do not connect it with a load to complete the circuit.

In case of motors, the voltage is given to the conductor to rotate the coil, due to rotation of the coil some voltage is induced backwards to the conductor which is called back EMF.

When a user process is interrupted or causes a processor exception, the x86 hardware switches the stack pointer to a kernel stac
andre [41]

Answer and Explanation

In x86, different stacks are used for kernel & user processes because of security purposes.

The kernel assigns the interrupt dispatch to a common kernel interrupt entry/exit

mechanism which saves pre-interrupt register state before summoning the registered handler(s).

When sending out an interrupt might launch a privilege and/or stack switch,

interrupts that occur while executing user process will switch to use the kernel stack in place at that point, without saving current state.

For the same cross-sectional area, which column provides the higher buckling load: a circular bar or a circular tube?
juin [17]

Answer:

Circular tube

Explanation:

Now for better understanding lets take an example

Lets take

Diameter of solid bar= 4\sqrt{2} cm

Outer diameter of tube =6 cm

Inner diameter of tube=2 cm

So from we can say that both tubes have equal cross sectional area.

We know that buckling load is given as P = \dfrac{\pi ^2EI}{L_e^2}      

If area moment of inertia(I) is high then buckling load will be high.

We know that  area moment of inertia(I)

For circular tube I = \dfrac{\pi }{64}(D_o^4-D_i^4)

For circular bar I = \dfrac{\pi }{64}D^4  

Now by putting the values

    For circular tube I=62.83 cm^4

  For circular bar I=50.26 cm^4

So we can say that for same cross sectional area the  area moment of inertia(I) is high for tube as compare to bar.So buckling load  will be higher in tube as compare to bar.

Fatigue failure occurs under the condition of (a) High elastic stress (b) High corrosivity (c) High stress fluctuations (d) High
Harlamova29_29 [7]

Answer:

Fatigue occurs under conditions of high elastic stress, high stress fluctuations and high rate of loading

Explanation:

 According to many definition of fatigue failure the fatigue occurs when in an especifyc point of the object there is involved many forces and tensions.

 That tensions needs to be big in magnitud, de variations of the efforts it has to be with a lot of amplitude and the loading in the object it has to be with a lot of number of cycles.

 If in the all of these three conditions are present the fatigue failure it would appear.
