You are given a semiconductor resistor made from silicon with an impurity concentration of resistivity 1.00×10−3ωm. the resistor
Vlad [161]

Answer: Resistance =3.2 \Omega , Current = 1.56 A, Voltage =4.99 V

The resistance,

R=\frac {\rho l}{A}

where, \rho is resistivity, A is the area and l is the length of the resistor.

It is given that:

\rho=1.0\times10^{-3}\Omega m

Length, l=2 mm

Area, A= width \times height=1.25 mm\times 0.5 mm=0.625 mm^2

Hence, R=\frac{1.0\times10^{-3}\Omega m \times 2\times10^{-3}m}{0.625\times10^{-6}m^2}=3.2\Omega

We know, Power, P=I^2R

\Rightarrow I=\sqrt{\frac{P}{R}}

P=7.81 W

I=\sqrt{\frac {7.81 W}{3.2\Omega}}=\sqrt{2.44}A=1.56A

We know, Voltage, V=IR=1.56\times3.2=4.99 V

Please help !!!!!!!!!!
Natalka [10]

Answer:

Lighthouse 1 during the day will be warmer, lighthouse 2 during the night will be warmer.

Explanation:

As the paragraph stated land absorbs heat and heats up faster than water. So during the day the lighthouse farthest away from the water will be hotter. But then the converse is true also land losses heat faster than water at night. So the water retains the heat from the day better making the lighthouse by the water warmer at night.

1. Who first published the classification of the elements that is the basis of our periodic table today?
Gre4nikov [31]
That particular group of elements is reffered to as the "Noble Gasses"--a title that comes from the fact that these gases are very "secure" and don't mix well with other elements.
