Answer:

1. Even though matter can be found all over the Universe, you will only find it in a few forms (states) on Earth. We cover five states of matter on the site. Each of those states is sometimes called a phase. There are many other states of matter that exist in extreme environments.

2. hot buttered popcorn, burns my tongue, smells buttery, looks yellowish-white, tastes like butter, and sounds like popping corn.

3. The water is a liquid so it has the same shape had the pan.

4.Paper clips are attracted to magnets because iron has a magnectic force.

5. The first (or smallest measurement) you would see is the hash marking millimeters, which is written as "mm". 1mm equals the thickness of a dime. The unit of measure that is most often displayed on a metric ruler would be centimeters written "cm". 10mm equals 1cm and 2.5cm is about equal to 1 inch. Centimeters are displayed for viewing like inches are, marked on the ruler in increments of 1, 2, 3, 4... and so on. Usually to 30cm which is slightly less than 12 inches.

6. Mass is used to measure the weight of an object. For example, you are measuring the mass of your body when you step on to a scale. In the metric system of measurement, the most common units of mass are the gram and kilogram.

The magnetic field inside a toroid is uniform.<br> a. True<br> b. False
jeyben [28]

The concept that must be applied to solve this problem is that of the magnetic field on Toroid described since the law of Ampere. Mathematically the magnetic field is determined as

B = \frac{\mu_0 NI}{2\pi r}

Where

\mu_0= Permeability constant

N = Number of loops

I = Current

r = Radius

As we can see the magnetic field inside a Toroid is NOT uniform, since it is highly proportional to the radius. Which means that as the radius increases the magnetic field decreases.

Therefore the correct answer is: FALSE

A sample of N-type silicon is at the room temperature. When an electric field with a strength of 1000V /cm is applied to the sam
V125BC [204]

Answer:

a) 222/cm^3

b) The Ec with respect to Ef and Ev = -0.107ev

c) Resistance, R = 467 ohms

Explanation:

(a) From the velocity and the applied electric field, we can calculate the mobility of holes:

υdp = µpε, µp = υdp/ε = 2×10^5/1000

= 200cm2/V.s

From a), we find Nd is equal to 4.5×1017/cm3

. Hence,

n = Nd = 4.5×10^17/cm3

, and p = ni^2/n

= ni^2/Nd

= 10^20 / 4.5×10^17 = 222/cm3

.

Clearly, the minority carrier is hole.

(b) The Fermi level with respect to Ec is

Ef = Ec - kTln(Nd/Nc) = Ec - 0.107 eV.

(c) R = ρL/A. Using Equation, we first calculate the resistivity of the sample:

σ = q(µn n + µp p) ≈ qµn n = 1.6×10^-19 × 400 × 4.5×10^17 = 28.8/Ω-cm, and

ρ= σ

-1 = 0.035 Ω-cm.

Therefore, R = (0.035) × 20µm / (10µm× 1.5µm) = 467 Ω.
