Consider a metal with an electron density of n = 7.2E28 m3. Calculate the Fermi energy of this metal. Enter the Fermi energy in "eV" units.

Answers

Answer 1

The Fermi energy is a crucial parameter in solid-state physics that determines the behavior of electrons in metals. It represents the energy required to remove the highest-energy electron from a metal at absolute zero temperature.

The value of the Fermi energy is an indicator of the metal's electronic properties, such as conductivity and thermal properties. It is a fundamental concept that helps us understand various phenomena in condensed matter physics, including semiconductors, superconductors, and magnetism. To calculate the Fermi energy, we can use the formula:

        E_F = (h^2 / 2m)(3π^2n)^(2/3)

where h is Planck's constant, m is the mass of an electron, and n is  the electron density.Plugging in the values, we get:

       E_F = (6.626E-34 J.s)^2 / 2(9.109E-31 kg)(3π^2(7.2E28 m^-3))^(2/3)

Simplifying this expression gives us:

        E_F = 28.9 eV

Therefore, the Fermi energy of the metal with an electron density of n = 7.2E28 m3 is 28.9 eV.

The tape in a videotape cassette has a total
length 213 m and can play for 2.4 h. As the
tape starts to play, the full reel has an outer
radius of 48 mm and an inner radius of 11 mm.
At some point during the play, both reels will
have the same angular speed.
What is this common angular speed?
Answer in units of rad/s.

Answers

Both reels will have the same angular speed of 0.0500 rad/sec.

What is angular speed?

angular speed is described as the rate at which an object changes it angles which we measure in radians in a given time

Given data:

The total length of videotape cassette is, L = 213 m.

The time interval for the play is, 2.4 = 2.4 x 3600

The outer radius of tape is, 48mm

The inner radius of tape is, 11mm

The videotape will undergo rotational motion and the value of angular velocity is given as,

w = v/ r  ... eqn (1)

Here, v is the linear speed of the cassette and r is the effective radius of the cassette, and its value is,

r =√ R²o + R²i/ 2

r = 49.24mm

And, the linear speed of the cassette is given as

v = L/ t

v = 213/ 8640

v = 0.02465 m/s

Substitute the values in equation (1) as

w = v/r

w =  0.02465/ 49.24

w = 0.0500 rad/sec.

Thus, we can conclude that at some point during the play, both reels will have the same angular speed of   0.0500 rad/sec.

An elevator weighing 230000 n is supported by a steel cable. What is the tension in the cable when the elevator accelerates down at a rate of 3. 7 m/s2 rounded to the nearest tenth?.

Answers

The required tension in the cable when the elevator accelerates down at a rate of 3. 7 m/s2 is  143163.26 N.

What is acceleration?

The rate at which velocity changes is called acceleration. Acceleration typically indicates a change in speed, but not necessarily. An item that follows a circular course while maintaining a constant speed is still moving forward because the direction of its motion is shifting.

According to question:

We have,

Weight = 230000N, Mass of elevator = 23469.38 kg

a = 3.7 m/s^2

So, by free body concept

230000 - T = 23469.38 kg(3.7)

230000 - T = 86836.74

T = 143163.26 N

If a 1600 kg automobile traveling at 42.8 m/s comes to a halt after its brakes are applied, how much can the temperature rise in each of the four 3.5 kg steel brake disks? Assume the disks are made of iron (cp = 448 J/kg·°C) and that all of the kinetic energy is distributed in equal parts to the internal energy of the brakes.

Answers

The temperature can rise 234° C in each of the four 3.5 kg steel brake disks.

What is law of conservation of energy?

Energy cannot be created or destroyed, according to the law of conservation of energy. However, it is capable of change from one form to another. An isolated system's total energy is constant regardless of the types of energy present.

According to law of conservation of energy:

1/2 × 1600 × 42.8² = 4 × 3.5 × 448 × Δt

Δt = (1600 × 42.8² )/( 2 ×  4 × 3.5 × 448)

Δt = 234° C.

Answers

The moon of Jupiter, Ganymede is the largest moon in the solar system. The mass of Jupiter when the orbital period and the distance from the centre of the orbit are given is calculated to be 1.57 × 10²⁷ kg.

The time required to complete one revolution in an orbit around the planet is known as the Orbital Time period of motion. The orbital distance's cube is directly proportional to the square of the time period.

Given that,

Orbital distance R = 1.07 × 10⁹ m

Time period T = 6.18 × 10⁵ s

We know the formula of time period as,

T² = 4 π² R³/ G M

where, M is the mass of Jupiter

G is the gravitational constant

(6.18 × 10⁵)² = 4 π² (1.07 × 10⁹)³/(6.67 × 10⁻¹¹) M

Making M as subject, we have,

M = 4 π² (1.07 × 10⁹)³/[ (6.67 × 10⁻¹¹) (6.18 × 10⁵)²] = 1.57 × 10²⁷ kg

A train tart from ret ,it move through 1km in 100 with uniform acceleration. What will be it peed at the end of 100

Answers

The train velocity (speed) at the end of 100km will be 10m/s.

The train starts from rest and moves through a distance of 1 km in 100 km with a uniform acceleration. The formula for velocity at the end of a certain time period is calculated by the following formula:

where:

v = final velocity (speed)

u = initial velocity (0 m/s, since the train starts from rest)

a = acceleration (0.01 m/s^2)

t = time (100,000 seconds, since the train travels 1 km in 100 km)

v = u + at

v = 0 + (0.01 m/s²)(100,000 s)

v = 10 m/s

It means at and after 100km onward, the train will be moving at a speed of 10m/s. The train's velocity increases linearly with time due to the uniform acceleration, and after 100 km of travel, it reaches a final velocity of 10 m/s.

Answers

The order of intermolecular forces among the given compounds will be as follows: H F > H Cl > H Br > H I

Electronegativity is defined as the property of the element to attract the shared pair of electrons towards itself.

Strongest intermolecular forces of attraction means that the electronegativity difference between the elements forming bond is more, more polar is the bond.

Electro negativities of the elements are:

Hydrogen: 2.1

Fluorine: 3.98

Chlorine: 3.16

Bromine: 2.96

Iodine: 2.66

Electro negativity difference in H F = 3.98 - 2.1 = 1.88

Electro negativity difference in H Cl = 3.16 - 2.1 = 1.06

Electro negativity difference in H Br = 2.96 - 2.1 = 0.86

Electro negativity difference in H I = 2.66 - 2.1 = 0.56
