Answer:

(a) Electrons

Explanation:

When there is a current flow in a transistor of NMOS so it is because of electrons as in NMOS the current is flowing from drain to source. Since the flow of electrons is from source to drain. Also the current would be inverse direction for electrons flow

Therefore the option A is correct

hence, the other options are incorrect

What is the multiplicity of the root x = -4?

just olya [345]

Answer:

See explanation

Explanation:

The multiplicity of a root of a polynomial equation is the number of times the root repeats.

Let $x=a$ be the root of $f(x)$ , then;

$(x-a)^1=0$ has a multiplicity of 1.

$(x-a)^2=0$ has a multiplicity of 2.

$(x-a)^3=0$ has a multiplicity of 3.

$(x-a)^m=0$ has a multiplicity of m, where m is a positive integer.

We were given the root $x=-4$ .

If $f(x)=(x+4)(x-6)^3$

Then the multiplicity of the root $x=-4$ is 1.

If $f(x)=(x+4)^4(x-6)^3$

Then the multiplicity of the root $x=-4$ is 4.

Since the polynomial function or equation is not given in the question, we cannot determine the multiplicity of this root.

But I hope with this explanation, you can refer to the original(complete) question and choose the correct answer.

Steam enters a turbine operating at steady state with a mass flow of 10 kg/s, a specific enthalpy of 3100 kJ/kg, and a velocity

likoan [24]

Answer:7989.86KW

Explanation:

Given data

$h_1$ =3100 KJ/kg

$\dot{m}$ =10kg/s

$V_1$ =30m/s

$Z_1$ =3m

$h_2$ =2300KJ/kg

$V_2$ =45m/s

$Z_2$ =0

using steady flow energy equation which is

$\dot{m}$ $\left (h_1+gZ_1+\frac{V_1^2}{g}\right )$ + $\dot{Q}$ = $\dot{m}$ $\left (h_2+gZ_2+\frac{V_2^2}{g}\right )\+$ $\dot{W}$

$10\left (3100+\frac{9.81\times 3}{1000}+\frac{30^2}{9.81\times 1000}\right )$ + $\dot{Q}$ = $10\left (2300+\frac{9.81\times 0}{1000}+\frac{45^2}{9.81\times 1000}\right )$ + $\dot{W}$
