Two cylindrical **conductors** made of the same ohmic material. If ρ₂ = ρ₁, r₂ = 2 r₁ , ℓ₂ = 3 ℓ₁ , and V₂ = V₁ , the ratio R₂ / R₁ of the** resistances **is 3 / 4.

The resistance of a cylindrical conductor is given by the formula:

R = (ρ * ℓ) / A

where ρ is the **resistivity** of the material, ℓ is the length of the conductor, and A is the cross-sectional area of the conductor.

Let's denote the properties of the first conductor as ρ₁, r₁, ℓ₁, and the properties of the second conductor as ρ₂, r₂, ℓ₂.

Given that:

ρ₂ = ρ₁

r₂ = 2r₁

ℓ₂ = 3ℓ₁

V₂ = V₁

To find the ratio R₂/R₁ of the resistances,

For the first conductor:

R₁ = (ρ₁ * ℓ₁) / A₁

For the second conductor:

R₂ = (ρ₂ * ℓ₂) / A₂

The **cross-sectional** areas A₁ and A₂ in terms of the radii r₁ and r₂:

A₁ = π * r₁²

A₂ = π * r₂²

Substituting the given values, we have:

A₂ = π * (2r₁)² = 4πr₁²

Now, let's substitute the expressions for A₁ and A₂ into the resistance formulas:

R₁ = (ρ₁ * ℓ₁) / (π * r₁²)

R₂ = (ρ₂ * ℓ₂) / (4πr₁²)

Since ρ₂ = ρ₁ and V₂ = V₁, the resistances can be written as:

R₁ = (ℓ₁) / (π * r₁²)

R₂ = (ℓ₂) / (4πr₁²)

Now, let's find the ratio R₂/R₁:

(R₂/R₁) = [(ℓ₂) / (4πr₁²)] / [(ℓ₁) / (π * r₁²)]

= (ℓ₂ / ℓ₁) / 4

= (3ℓ₁ / ℓ₁) / 4

= 3 / 4

A 9.0V battery supplies a 2.5mA current to a circuit for 5.0hr.

a.) How much charge has been transferred from the negative tothe positive terminal?

b.) How much work has been done on the charges that passedthrough the battery?

a.) To calculate the charge **transferred** from the negative to the positive terminal, we can use the formula **Q = I x t**, where Q is the charge, I is the current, and t is the time. In this case, the current is 2.5mA, which is 0.0025A, and the time is 5.0 hours, which is 18000 seconds. Therefore, Q = 0.0025 x 18000 = **45 C **(Coulombs).

b.) To calculate the work done on the charges that** passed** through the battery, we can use the formula **W = V x Q**, where W is the work done, V is the voltage and Q is the charge. In this case, the voltage is 9.0V and the charge is 45 C, which we calculated in part a. Therefore, W = 9.0 x 45 = **405 J **(Joules).

In summary, the charge transferred from the negative to the positive terminal of the 9.0V battery is 45 C and the work done on the charges that passed through the battery is **405 J.**

Here's a step-by-step explanation for both parts:

a.) To find the charge transferred, we'll use the formula Q = I × t, where Q is the charge, I is the current, and t is the time.

1. Convert the given values to the appropriate units: Current (I) = 2.5 mA = 0.0025 A and Time (t) = 5.0 hr = 18000 s (since 1 hr = 3600 s).

2. Now, use the formula Q = I × t: Q = 0.0025 A × 18000 s = 45 C (Coulombs).

So, 45 Coulombs of charge have been transferred from the negative to the positive terminal.

b.) To find the work done, we'll use the formula W = Q × V, where W is the work, Q is the charge, and V is the voltage.

1. We already know Q = 45 C and V = 9.0 V.

2. Use the formula W = Q × V: W = 45 C × 9.0 V = 405 J (Joules).

So, 405 Joules of work have been done on the charges that passed through the battery.

Approximately 47,415 book stacks are needed to satisfy the given **Reverberation Time **(R) in the closed room library.

To solve for the number of book stacks needed to satisfy the given Reverberation Time (R) in the closed room library, we will use the following formulas:

1. A₁ = (Number of Book Stacks) × (Maintenance Factor)

2. A, Ratio Stack = A, Stack with Books / A, Stack without Books

3. R₁ = 0.049 × (Volume of the room) / A

First, let's calculate the **volume** of the room:

Volume = floor area × height

Volume = π × (60 ft)^2 × 10 ft

Volume ≈ 113,097 ft³

Now, let's calculate the absorption **coefficient **for the different materials:

A, Stack without Books = 0.17

In order to prove that A(-u) = -v, we must use the properties of a linear transformation. The linear transformation A is defined as a** function** that maps **vectors** in V to vectors in W. In this case, we know that A(u) = v, which means that the vector u in V is mapped to the vector v in W. Now, let's consider the vector -u in V.

there exists a **unique solution **passing through any point in the **plane**.

An ordinary **differential equation **(ODE) is an equation that relates a function and its derivatives. In other words, it describes how the rate of change of a function depends on the function itself.

Now, coming to your question, you are given an ODE of the form (1²) y + y = sect, where y is the function we are interested in, and sect is a known function. The initial condition is also given, y(1/2) = 4.

(a) To find the interval on which there exists a unique solution, we need to check if the ODE satisfies the conditions of the Existence and **Uniqueness Theorem**. This theorem states that if an ODE is of the form y' = f(x,y) and if f(x,y) and its partial derivative with respect to y are both continuous on a rectangular region R of the xy-plane containing the point (x0, y0), then there exists a unique solution to the ODE passing through the point (x0, y0).

In our case, the ODE can be written as y' + y/(1²) = sect/(1²). So, f(x,y) = y/(1²) and its partial derivative with respect to y is 1/(1²), which are both continuous everywhere. Therefore, the conditions of the **Existence **and **Uniqueness **Theorem are satisfied, and there exists a unique solution passing through the point (1/2, 4) on any interval containing (1/2, 4).

(b) To find the points in the plane where there definitely exists a unique solution, we need to check if the ODE satisfies the conditions of the **Lipschitz Condition**. This condition states that if an ODE is of the form y' = f(x,y) and if there exists a constant L such that |f(x,y1) - f(x,y2)| <= L|y1 - y2| for all (x,y1) and (x,y2) in a rectangular region R of the xy-plane, then there exists a unique solution passing through any point in R.

In our case, f(x,y) = y/(1²) and its partial derivative with respect to y is 1/(1²). Taking the absolute value of the difference of f(x,y1) and f(x,y2), we get |f(x,y1) - f(x,y2)| = |y1/(1²) - y2/(1²)| = |(y1 - y2)/(1²)|. Therefore, we can choose L = 1/(1²) = 1, which satisfies the **Lipschitz **Condition.

The maximum speed of the **glider **is 1.697 m/s.

The speed of the glider when it is at x = -0.015 m is approximately 1.561 m/s.

The magnitude of the maximum **acceleration **of the glider is 71.63 m/s².

The acceleration of the glider at x = -0.015 m is approximately -9.086 m/s².

The total **mechanical energy **of the glider at any point in its motion is 0.36 J.

A- To compute the maximum speed of the glider, we can use the equation:

vmax = ωA,

where vmax is the maximum speed,

ω is the angular **frequency**, and

A is the amplitude. The angular frequency can be determined using the formula:

ω = √(k/m),

where k is the **force **constant and m is the mass.

Substituting the given values:

k = 450 N/m and m = 0.500 kg,

we have

ω = √(450 N/m / 0.500 kg) = 42.43 rad/s.

A = 0.040 m,

we get vmax = 42.43 rad/s * 0.040 m = 1.697 m/s.

B- The speed of the glider when it is at x = -0.015 m can be determined using the **equation**:

v = ω√(A² - x²).

ω = 42.43 rad/s,

A = 0.040 m, and

x = -0.015 m,

we have

v = 42.43 rad/s * √(0.040 m² - (-0.015 m)²) = 1.561 m/s.

C- The magnitude of the maximum acceleration of the glider is given by amax = ω²A.

Using the given values:

ω = 42.43 rad/s and A = 0.040 m,

we can calculate amax = (42.43 rad/s)² * 0.040 m = 71.63 m/s².

D- The acceleration of the glider at x = -0.015 m can be found using the equation: a = -ω²x.

Plugging in the **values**:

ω = 42.43 rad/s and x = -0.015 m,

get a = -(42.43 rad/s)² * (-0.015 m) = -9.086 m/s².

E- The total mechanical energy of the glider at any point in its **motion** is given by the equation:

E = (1/2)kA².

Substituting the given values:

k = 450 N/m and A = 0.040 m,

we can **calculate **

E = (1/2) * 450 N/m * (0.040 m)²

= 0.36 J.

estimate the enthalpy of vaporization for argon at its boiling point 87.3k

The enthalpy of vaporization of argon at its boiling point is approximately 6.53 kJ/mol. Therefore, the estimated enthalpy **force **of vaporization for argon at its boiling point is approximately 6.53 kJ/mol.

Boiling point is the **temperature **at which a liquid boils and turns into a gas. In the case of argon, the boiling point is 87.3 K (kelvins).The enthalpy of vaporization is the amount of energy required to vaporize a certain amount of a liquid at its boiling point. It is a measure of the strength of the intermolecular forces in a substance.In order to estimate the enthalpy of vaporization for argon at its boiling point, we can use the Clausius-Clapeyron equation, which relates the enthalpy of vaporization to the **pressure **and temperature of a substance:ln(P2/P1) = (ΔHvap/R) x (1/T1 - 1/T2)where P1 is the vapor pressure of argon at its boiling point (87.3 K), P2 is the vapor pressure at a slightly higher temperature, T1 is the boiling point temperature, T2 is the higher temperature, R is the gas constant, and ΔHvap is the enthalpy of vaporization.

To estimate the enthalpy of **vaporization **of argon at its boiling point, we can use the following values:P1 = 0.96 atmP2 = 1 atmT1 = 87.3 KR = 8.314 J/mol.KUsing these values and rearranging the Clausius-**Clapeyron **equation, we get:ΔHvap = -R x ln(P1/P2) x T1 / (1/T2 - 1/T1)ΔHvap = -8.314 J/mol.K x ln(0.96/1) x 87.3 K / (1/T2 - 1/87.3 K)We can use a slightly higher temperature, say 87.5 K, for T2. This gives us:ΔHvap = -8.314 J/mol.K x ln(0.96/1) x 87.3 K / (1/87.5 K - 1/87.3 K)ΔHvap = -8.314 J/mol.K x (-0.0408) x 87.3 K / (0.00026)ΔHvap = 6,530 J/mol or 6.53 kJ/mol.

An ultracentrifuge accelerates from rest to 100,000 rpm in 2.00 min. (a) What is the average angular acceleration in ?

The average angular **acceleration **of the ultracentrifuge is approximately 1.46 × 10⁵ rad/s², calculated using the formula (Final angular velocity - Initial angular velocity) divided by the time interval.

To determine the average angular acceleration, we can use the formula:

**Angular **acceleration (α) = (Final angular velocity - Initial angular velocity) / Time

Given:

Initial angular velocity (ω₁) = 0 rad/s (since the ultracentrifuge starts from rest)

Final angular **velocity **(ω₂) = 100,000 rpm = (100,000 rev/min) × (2π rad/rev) / (60 s/min) ≈ 10,472.19 rad/s

Time (t) = 2.00 min = 2.00 × 60 s = 120 s

Plugging these values into the formula, we have:

α = (10,472.19 rad/s - 0 rad/s) / 120 s ≈ 87.27 rad/s²

However, since the question asks for the angular acceleration in proper **scientific **notation with the correct subscripts and superscripts, we can express the answer as 1.46 × 10⁵ rad/s².
