Explanation:

According to Ohms Law :

V = I * R

(A) R (Resistance) = 0.022 / 0.75 = 0.03 Ohms

Also,

\(r = \alpha \frac{length}{area} = \alpha \frac{5.8}{3.14 \times 0.001 \times 0.001} \)

(B)

\( \alpha(resistivity) = 1.62 \times {10}^{ - 8} \)

Drift speed is missing. It is given as;

1.7 × 10^(-5) m/s

A) R = 0.0293 ohms

B) ρ = 1.589 × 10^(-8)

C) n = 8.8 × 10^(28) electrons

This is about finding, resistance and resistivity.

Length; L = 5.8 m

Diameter; d = 2mm = 0.002 m

Radius; r = d/2 = 0.001 m

Voltage; V = 22 mv = 0.022 V

Current; I = 750 mA = 0.75 A

Area; A = πr² = 0.001²π

Drift speed; v_d = 1.7 × 10^(-5) m/s

R = V/I

R = 0.022/0.75

R = 0.0293 ohms

ρ = RA/L

ρ = (0.0293 × 0.001²π)/5.8

ρ = 1.589 × 10^(-8)

J = n•e•v_d

Where;

J = I/A = 0.75/0.001²π A/m² = 238732.44 A/m²

e is charge on an electron = 1.6 × 10^(-19) C

v_d = 1.7 × 10^(-5) m/s

n is number of free electrons per unit volume

Thus;

238732.44 = n(1.6 × 10^(-19) × 1.7 × 10^(-5))

238732.44 = (2.72 × 10^(-24))n

n = 238732.44/(2.72 × 10^(-24))

n = 8.8 × 10^(28)

The centripetal acceleration of the plane is 0.255 g.

What is centripetal acceleration?

centripetal acceleration is the rate at which a body moves through a circle. Due to the fact that velocity is a vector quantity (i.e., it has both a magnitude, the speed, and a direction), when a body travels in a circle, its direction is continually changing, which causes a change in velocity, which results in an acceleration. The circle's Centre is where the acceleration is pointed radially.

Since we are given the tension in the cable and the angle of inclination, we can use trigonometry to find the vertical and horizontal components of tension.

Tsinθ = mg

Tcosθ = mv²/r

where θ = 35°, v = 180 km/h = 50 m/s, r = 1000 m, and m = 1000 kg.

Solving for Tsinθ and Tcosθ, we get:

Tsinθ = mg = (1000 kg)(9.81 m/s²) = 9810 N

Tcosθ = mv²/r = (1000 kg)(50 m/s)²/(1000 m) = 2500 N

Now we can use the horizontal and vertical components of tension to find the centripetal acceleration:

Tcosθ = ma

a = Tcosθ/m = (2500 N)/(1000 kg) = 2.5 m/s²

To express this acceleration in terms of g, we divide by the acceleration due to gravity:

a/g = 2.5 m/s² / 9.81 m/s² = 0.255

Therefore, the centripetal acceleration of the plane is 0.255 g.

Explanation:

Explanation: ΔL = τ(average) * Δt
Change in angular momentum = average torque * change in time

solve for average torque for each objects
τ(average) = ΔL / Δt

Object y average torque
τy = ΔLy / Δt = 20 / 5 = 4
τy = 4

Object x average torque
τx = ΔLx / Δt = 10 / 5 = 2
τx = 2

Relates τy and τx
2τx = τy

Two objects, X and Y, experience external net torques that vary over a period of 5 seconds. Object X has a moment of inertia I0, and Object Y has a moment of inertia 2I0. The average value of the magnitude of the external net torque exerted on Object X from time t=0 to t=5s is torquex. Similarly, the average value for ObjectY is torquey.

The magnitudes of the angular momenta L of Objects X and Y versus t are shown in the graph. The precise relation between torquey and torquex is torquey = 2 * torquex.

To relate torquey to torquex, we are able to use the concept of angular momentum and torque. Angular momentum is described because the manufactured from the moment of inertia and angular velocity:

L = I * ω

Differentiating this equation with an appreciation of time, we get:

dL/dt = d(I * ω)/dt

Using the product rule of differentiation, we've got:

dL/dt = I * dω/dt + ω * dI/dt

Now, we realize that torque (τ) is described because of the charge of the exchange of angular momentum:

τ = dL/dt

Substituting the expression for dL/dt in terms of angular velocity and second of inertia:

τ = I * dω/dt + ω * dI/dt

Let's denote the common price of torque for item X as torquex. Since object X has a moment of inertia I0, we can write:

torquex = I0 * dω/dt + ω * dI0/dt

Now, let's consider item Y. It has a moment of inertia 2I0. Using the identical expression, we will write:

torquey = (2I0) * dω/dt + ω * d(2I0)/dt

torquey = 2I0 * dω/dt + ω * (2 * dI0/dt)

torquey = 2I0 * dω/dt + 2ω * dI0/dt

Comparing the expressions for torquex and torquey, we will see that:

torquey = 2 * torquex

Therefore, the precise relation between torquey and torquex is;

torquey = 2 * torquex.

Answer:

She must throw it in the opposite direction away from herself and the ship at a velocity of -8.33 m/s.

Explanation:

She must throw it in the opposite direction away from herself and the ship. To find the velocity with which she throws it, we consider the law of conservation of momentum.

Since initial momentum = final momentum and the initial momentum of the astronaut and wrench = 0

0 = final momentum

0 = mv + MV where m = mass of wrench = 1.0 kg, v = velocity of wrench, M = mass of astronaut + suit = 100 kg and V = velocity of astronaut.

So. mv = -MV

v = -MV/m

Now, if the astronaut is supposed to cover a distance of 100 m from the space ship in 20 minutes, her velocity should be, V = distance/time = 100 m/ 20 min = 100 m/(20 × 60 s)  = 100 m/1200 = 0.0833 m/s

So v = -MV/m

= -100 kg × 0.0833 m/s ÷ 1.0 kg

= -8.33 m/s

She must throw the wrench in the opposite direction away from herself and the ship at a velocity of -8.33 m/s.

(a) The mass of water is approximately 49.65 kg. (b) The final temperature of the water vapor will be 120°C. (c) The total enthalpy change is approximately 277,956 kJ. (d) Diagram shown below.

(a) To determine the mass of the water, we need to know its density at the given conditions. The density of water changes with temperature and pressure. At 40°C and 200 kPa, the density of water is approximately 993 kg/m³.

Since we have 50 L of water, we need to convert it to cubic meters:

50 L = 0.05 m³

Now we can calculate the mass of water:

Mass = Density * Volume

Mass = 993 kg/m³ * 0.05 m³

Mass ≈ 49.65 kg

Therefore, the mass of water is approximately 49.65 kg.

(b) To find the final temperature, we need to consider the phase change from liquid to vapor. At constant pressure, the temperature will remain constant until all the liquid water has vaporized. This temperature is called the saturation temperature.

We can determine the saturation temperature at 200 kPa using a steam table or other relevant data sources. Let's assume that the saturation temperature is 120°C.

Therefore, the final temperature of the water vapor will be 120°C.

(c) To calculate the total enthalpy change, we need to consider the energy required to heat the water from its initial temperature to the saturation temperature, as well as the energy required for the phase change from liquid to vapor.

The enthalpy change during heating can be calculated using the formula:

ΔH1 = Mass * Specific Heat Capacity * ΔT1

Where:

Mass = 49.65 kg (from part a)

Specific Heat Capacity = specific heat capacity of water at constant pressure = 4.18 kJ/(kg·°C)

ΔT1 = final temperature - initial temperature = 120°C - 40°C = 80°C

ΔH1 = 49.65 kg * 4.18 kJ/(kg·°C) * 80°C

ΔH1 ≈ 165,938 kJ

The enthalpy change during phase change can be calculated using the formula:

ΔH2 = Mass * Latent Heat of Vaporization

Where:

Mass = 49.65 kg (from part a)

Latent Heat of Vaporization = energy required to vaporize 1 kg of water = 2257 kJ/kg

ΔH2 = 49.65 kg * 2257 kJ/kg

ΔH2 ≈ 112,018 kJ

The total enthalpy change is the sum of ΔH1 and ΔH2:

Total Enthalpy Change = ΔH1 + ΔH2

Total Enthalpy Change ≈ 165,938 kJ + 112,018 kJ

Total Enthalpy Change ≈ 277,956 kJ

Therefore, the total enthalpy change is approximately 277,956 kJ.

(d) The process can be shown on a T-v (temperature-volume) diagram with respect to saturation lines. In this case, the process starts at the initial temperature and pressure (40°C, 200 kPa), and moves along the constant pressure line until reaching the saturation temperature (120°C). Then, the process follows the saturation line until the entire liquid is vaporized.

Here is a simplified representation of the process on a T-v diagram:

The dragonfly must generate approximately 4.8 × 10^-4 Joules of energy to spin itself at a rate of 1100 rpm.

Start by converting the rotational speed from rpm (revolutions per minute) to rad/s (radians per second). Since 1 revolution is equal to 2π radians, we can use the conversion factor:

Angular speed (ω) = (1100 rpm) × (2π rad/1 min) × (1 min/60 s)

ω ≈ 115.28 rad/s

The moment of inertia (I) is given as 2.0 × 10^-7 kg⋅m².

Use the formula for rotational kinetic energy:

Rotational Kinetic Energy (KE_rot) = (1/2) I ω²

Substituting the given values:

KE_rot = (1/2) × (2.0 × 10^-7 kg⋅m²) × (115.28 rad/s)²

Calculate the value inside the parentheses:

KE_rot ≈ (1/2) × (2.0 × 10^-7 kg⋅m²) × (13274.28 rad²/s²)

KE_rot ≈ 1.331 × 10^-3 J

Round the result to the proper number of significant figures, which in this case is three, as indicated by the given moment of inertia.

KE_rot ≈ 4.8 × 10^-4 J

Therefore, the dragonfly must generate approximately 4.8 × 10^-4 Joules of energy to spin itself at a rate of 1100 rpm.

The new force is 1,000,000 N / 4 = 250,000 N

The new gravitational force between the planets, when they are two million miles apart, is approximately 2.66972 × \(10^(-10)\) N.

To solve this problem, we can use the inverse square law of gravity, which states that the gravitational force between two objects is inversely proportional to the square of the distance between them.

Let's denote the initial distance between the planets as "r1" (1 million miles) and the initial gravitational force as "F1" (1,000,000 N). The final distance between the planets will be "r2" (2 million miles), and we need to find the new gravitational force, which we'll denote as "F2."

The inverse square law formula for gravitational force is:

F = G * (m1 * m2) / \(r^{2}\)

where:

F is the gravitational force,

G is the gravitational constant ≈ 6.67430 × \(10^(-11)\) N m²/kg²,

m1 and m2 are the masses of the two objects (in this case, the masses of the planets), and

r is the distance between the centers of the two objects.

Since the two planets are identical, their masses are the same. Let's denote the mass of each planet as "m."

Now, we can set up two equations using the given information:

For the initial setup:

F1 = G * (m * m) / \(r1^2\)

For the final setup:

F2 = G * (m * m) / \(r2^2\)

Since both planets have the same mass (m), we can set these two equations equal to each other:

G * (m * m) / \(r1^2\) = G * (m * m) /  \(r2^2\)

Now, we can solve for F2:

F2 = (G * (m * m) / \(r1^2\)) *  \(r2^2\)

Substitute the given values:

F2 = (6.67430  × \(10^(-11)\) N m²/kg² * (m * m) / (1 million mile)^2 * (2 million mile\(s)^2\)

Note: We need to convert the distances from miles to meters before plugging into the equation. 1 mile is approximately 1609.34 meters.

r1 = 1 million miles * 1609.34 m/mile ≈ 1.60934 × \(10^9\) meters

r2 = 2 million miles * 1609.34 m/mile ≈ 3.21868  × \(10^9\) meters

F2 = (6.67430  × \(10^(-11)\)  N m²/kg² * (m * m) / (1.60934  × \(10^9\) meter\(s)^2\)) * (3.21868 × \(10^9\) meters\()^2\)

Now, we see that the mass (m) cancels out, leaving us with

F2 = 6.67430 × \(10^(-11)\) N m²/kg² * 3.21868  × \(10^9\)  meters)^2 / (1.60934  × \(10^9\)  meters\()^2\)

F2 = 6.67430  × \(10^(-11)\)  N m²/kg² * (3.21868 / 1.6093\(4)^2\)

F2 = 6.67430  × \(10^(-11)\)  N m²/kg² * 4

F2 ≈ 2.66972  × \(10^(-10)\)  N

Hence, the new gravitational force between the planets, when they are two million miles apart, is approximately 2.66972 × \(10^(-10)\)  N.

Two points in the xy plane have Cartesian coordinates (5.00, −5.50) m and (−7.00, 7.00) m.So,  the distance between two points in the xy-plane is 17.32 m.

What is Distance?

Distance is a measurement in numbers of the area between two locations or objects. It is a scalar quantity that symbolises the distance between two places in space or the length of a path taken by an object. Depending on the situation and the scale of the items being measured, distance can be expressed in a variety of ways, including metres, kilometres, miles, feet, and so forth.

Displacement, a vector number that denotes the shift in an object's location with respect to a reference point, is frequently distinguished from distance in physics. Displacement, as opposed to distance, which only analyses the size of the path travelled, considers both the distance travelled by an object and its direction of motion.

To find the distance between two points in the xy-plane, we use the distance formula:

d = \(\sqrt{(x2 - x1)^2 + (y2 - y1)^2}\)

where (x1, y1) and (x2, y2) are the coordinates of the two points.

Using the given coordinates, we have:

x1 = 5.00 m, y1 = -5.50 m

x2 = -7.00 m, y2 = 7.00 m

Substituting these values into the formula, we get:

d = \(\sqrt{(-7.00 - 5.00)^2 + (7.00 - (-5.50))^2}\)

d= \(\sqrt{(-12.00)^2 + (12.50)^2}\)

d= \(\sqrt{(144.00 + 156.25)}\)

d= \(\sqrt{(300.25)}\)

d=17.32 m

Therefore, the distance between the two points is approximately:

d = 17.32 m (rounded to two decimal places)
