Answer:

displacement

Explanation:

Hookes Law describes the elastic properties of materials only in the range in which the force and displacement are proportional (displacement = change in length).

The thicker wire has one-fourth the resistance of the thinner wire.

The characteristic of a substance that prevents the flow of current is known as resistance. The free electrons begin to move in a specific direction when a voltage is applied across the conductor. These electrons collide with atoms or molecules as they move, creating heat in the process. These atoms or molecules prevent free electrons from moving through a substance. Resistance is represented by the symbol R.

Specific resistance is another name for resistivity. A substance with certain dimensions, such as one meter in length and a cross-sectional area of one square meter, has a resistance that is represented by its resistivity. Resistivity or specific resistance is represented by ρ.

The relation between resistance R and resistivity ρ is given as:

                                                R = ρL/A

where,

R = resistance of the conductor

ρ =  resistivity of the material

L = length of the conductor

A = cross-sectional area of the conductor

Given,

r₁ = 2r₂

L₁ = L₂

where

r₁ = radius of the first conductor

r₂ = radius of the second conductor

L₁ = length of the first conductor

L₂ = length of the second conductor

To find

R₁/R₂ =?  (the ratio of R₁ and R₂)

If the radius is twice the other then the area will become,

A₁ = π r₁²

A₂ = π r₂²

A₁ = π (2r₂)²

    = 4π r₂²

Therefore,

A₁ = 4 A₂

Now put the values in formula,

R = ρL/A

R₁/R₂ = ρ L₁ A₂/  ρ L₂ A₁

R₁/R₂ = L A₂/ L (4A₂)

R₁/R₂ = 1/4

R₁ = R₂/4

Hence, the thicker wire with twice the radius of thin wire has one-fourth the resistance of the thinner wire.

I understand the question you are looking for is this:

How do the resistances of two conducting wires compare if they have the same length, but one is twice the radius of the other?

(a) The thicker wire has half the resistance of the thinner wire

(b) The resistance is the same in both wires

(c) The thicker wire has one-fourth the resistance of the thinner wire

(d) The thicker wire has twice the resistance of the thinner wire.

Explanation:

This means that the string is vibrating at a fundamental frequency of 340.5 Hz when it is in its first harmonic state.

The fundamental frequency of a string is the lowest frequency at which it vibrates, and is sometimes referred to as the first harmonic. The higher harmonics are integer multiples of the fundamental frequency, so if you know the frequency of one of the higher harmonics, you can find the fundamental frequency.

In this case, you have measured the fourth harmonic, with a frequency of 1,362 Hz. Therefore, the fundamental frequency can be found by dividing the harmonic frequency by the harmonic number:

fundamental frequency = harmonic frequency / harmonic number

fundamental frequency = 1,362 Hz / 4 = 340.5 Hz

The higher harmonics are multiples of the fundamental frequency, so the fourth harmonic will have a frequency of 4 times the fundamental frequency.

Answer:

  12.5 A

Explanation:

You want the current intensity in an iron wire 3.14 m long with a radius of 0.5 mm connected to a 5V battery, given the resistivity of iron is 10^-7 Ω·m.

The resistance of the wire is proportional to wire length, and inversely proportional to area:

  R = ρl/A

  R = (10^-7 Ω·m)(3.14 m)/(3.14·(0.5·10^-3 m)²) = (1/.25)·10^-1 Ω = 0.4 Ω

The current is given by Ohm's law:

  I = V/R

  I = (5 v)/(0.4 Ω) = 12.5 A

The current intensity is 12.5 amperes.

Explanation:

A property that can be observed without changing the identity of a substance is a Physical Property.

A physical property is a property that can be observed or measured without changing the composition of the substance. They are used to observe and describe matter. Texture, color, smell. Melting point, boiling point, density, solubility, polarity, electrical conductivity, ductility, ductility, luster, sound intensity, etc., are some examples of physical properties.

Physical properties are often characterized as strength and general properties. Intensive properties do not depend on the size or extent of the system, nor on the amount of matter in the object, while extensive properties exhibit an additive relationship. These classifications are generally valid only if the smaller subdivisions of the sample do not interact in a physical or chemical process when combined.

Goods can also be classified according to the meaning of their nature. For example, isotropic properties do not vary with viewing direction, while anisotropic properties have spatial variance.

The amount of time required to generate energy on the exercise bike is almost impractical, and other sources of energy should be considered.

Let's start with calculating the amount of energy that the AC unit consumes in a day.

Power = Voltage x Current

The power consumption of the AC unit is 3500 Watts.

Time = Power / Voltage x Current (Ohm's Law)

Assuming that your home uses 120 volts AC, the amount of current needed is as follows:

Current = Power / Voltage

= 3500 W / 120 V

= 29.16 A.

The time required to operate the AC unit for four hours per day is:

Time = Power / Voltage x Current

= 3500 W x 4 hr / 120 V x 29.16 A

= 12 hours.

Now, if you can generate a consistent power of 300 watts on the exercise bike, the amount of time you'd need to work out each day to keep the AC unit running for four hours would be:

Time required for the exercise bike = Time for AC Unit x (Power required by AC unit / Power generated by exercise bike)

Time required for the exercise bike = 4 hours x (3500 W / 300 W)

Time required for the exercise bike = 46.7 hours.

Using an exercise bike to generate electricity is a great idea, but it would be difficult to generate enough energy to keep large home appliances running, such as a central AC unit.

In this case, the amount of time required to generate energy on the exercise bike is almost impractical, and other sources of energy should be considered.

Explanation:

Answer:-50 J

Explanation:

Answer: -50 N

Explanation:

Given information: The average method reports the following unit data for the forming department. Units completed in the forming department are transferred to the painting department. Production cost information for the forming department follows.

Direct materials:
Units completed during the period = 45,000 units
Ending work in process inventory = 5,000 units
Direct materials cost = $202,500

Conversion costs:
Units completed during the period = 45,000 units
Ending work in process inventory = 5,000 units
Conversion cost = $189,000

a. Calculation of equivalent units of production for both direct materials and conversion for the forming department:
Equivalent units of production = Units completed during the period + (Ending work in process inventory * Degree of completion)
Direct materials:
Equivalent units of production = 45,000 + (5,000 * 50%) = 47,500 units

Conversion costs:
Equivalent units of production = 45,000 + (5,000 * 60%) = 48,000 units

b. Calculation of the cost per equivalent unit of production for both direct materials and conversion for the forming department:
Cost per equivalent unit of production = Total cost for the period / Equivalent units of production

Direct materials:
Cost per equivalent unit of production = $202,500 / 47,500 units = $4.26 per unit

Conversion costs:
Cost per equivalent unit of production = $189,000 / 48,000 units = $3.94 per unit

c. Calculation of the cost assigned to the forming department's output using the weighted average method:
Total cost = Cost of units transferred out + Cost of ending work in process inventory
Cost of units transferred out = Number of units transferred out * Cost per equivalent unit of production
Cost of ending work in process inventory = Number of units in ending work in process inventory * Cost per equivalent unit of production

Direct materials:
Cost of units transferred out = 40,000 * $4.26 per unit = $170,400
Cost of ending work in process inventory = 5,000 * $4.26 per unit = $21,300
Total cost = $170,400 + $21,300 = $191,700

Conversion costs:
Cost of units transferred out = 40,000 * $3.94 per unit = $157,600
Cost of ending work in process inventory = 5,000 * $3.94 per unit = $19,700
Total cost = $157,600 + $19,700 = $177,300

The water velocity from the nozzle is approximately 27.33 m/s.

The Bernoulli equation, which connects a fluid's pressure, velocity, and height in a system, must be used to address this issue.

Let's start by converting the hose and nozzle's diameter from inches to meters:

Hose diameter: 5.9999 in = 0.1524 m

Nozzle diameter: 0.73 in = 0.018542 m

Next, let's find the cross-sectional area of the nozzle, which we'll need for calculating the velocity of the water:

Nozzle area: A = πr = π(0.009271 m)² ≈ 0.000269 m²

Now we can use the Bernoulli equation to solve for the velocity of the water:

P + 1/2ρv² + ρgh = constant

where:

P is the absolute pressure of the water at the pump (5 atm² = 506625 Pa)

ρ is the density of the water (1000 kg/m³)

v is the velocity of the water at the nozzle (what we're solving for)

g is the acceleration due to gravity (9.81 m/s²)

h is the height difference between the pump and nozzle (10 m)

At the pump, the water is at rest, so the velocity term is 0. We'll set the constant to the pressure at the nozzle, which is the atmospheric pressure (101325 Pa).

P + 1/2ρv² + ρgh = 101325 Pa

Solving for v:

1/2ρv² = 101325 - P - ρgh

v² = 2(101325 - P - ρgh) / ρ

v = √(2(101325 - P - ρgh) / ρ)

Substituting in the values:

v = √(2(101325 - 506625 - 10009.8110) / 1000)

v ≈ 27.33 m/s

So the water velocity from the nozzle is approximately 27.33 m/s.

The water velocity from the nozzle is approximately 15.3 m/s.

When a fireman climbs a 10 m high ladder carrying a hose with a 5.9999 in diameter and a 0.73 in diameter nozzle, and the pump has an absolute pressure of 5 atm, the water velocity from the nozzle can be calculated. To determine this, we can use the principles of fluid mechanics.

First, we need to convert the given diameters from inches to meters. Since 1 inch is equal to 0.0254 meters, the hose diameter is 0.1524 m, and the nozzle diameter is 0.018542 m.

The velocity of water can be determined using the Bernoulli's equation, which states that the sum of pressure, kinetic energy, and potential energy per unit volume is constant in a steady flow of an incompressible fluid. We can neglect the potential energy change since the ladder's height is relatively small compared to the diameter of the nozzle.

Applying the Bernoulli's equation, we can calculate the velocity using the formula:

(v^2)/2 + P/(ρ*g) = constant

Where:

v is the velocity of the water,

P is the absolute pressure,

ρ is the density of the water, and

g is the acceleration due to gravity.

Given that the absolute pressure is 5 atm, which is equivalent to 506625 Pa, and the density of water is 1000 kg/m^3, we can substitute these values into the equation:

(v^2)/2 + 506625/(1000*9.8) = constant

Simplifying the equation, we find:

(v^2)/2 + 5173.45 = constant

Since we are interested in the velocity of the water, we can solve for v:

(v^2)/2 = constant - 5173.45

(v^2)/2 = constant - 5173.45

v^2 = (constant - 5173.45) * 2

v = sqrt((constant - 5173.45) * 2)

Now, we can calculate the constant using the initial conditions where the fireman is at the top of the ladder:

(0^2)/2 + 506625/(1000*9.8) = constant

0 + 5173.45 = constant

Therefore, the constant is 5173.45. Substituting this value back into the equation, we have:

v = sqrt((5173.45 - 5173.45) * 2)

v = sqrt(0 * 2)

v = sqrt(0)

v = 0 m/s

This means that when the fireman reaches the top of the ladder, there is no water velocity from the nozzle since the water is not flowing yet.

In conclusion, the water velocity from the nozzle is approximately 15.3 m/s, but when the fireman reaches the top of the ladder, there is no water velocity initially. The velocity gradually increases as the water starts to flow.

The amount of energy required to heat 600 g of iron from 25°C to 60°C can be calculated using the formula:

Q = mcΔT

where Q is the amount of energy (in joules), m is the mass of the iron (in grams), c is the specific heat of iron (in J/g°C), and ΔT is the change in temperature (in °C).

Substituting the given values, we get:

Q = (600 g)(0.41 J/g°C)(60°C - 25°C)

Q = (600 g)(0.41 J/g°C)(35°C)

Q = 8610 J or 8.61 kJ (to three significant figures)

v = final Velocity = 0 (at maximum height)

u = Initial Velocity = 4

a = g downward acceleration = - 10

0 = 4^2 + 2(-10)(S)

0 = 16 - 20S

20S = 16

S = 16 / 20

S = 0.8m

Maximum Height attained = 0.8m

The law of conservation of energy tells us that the total energy of a system remains constant. Therefore, the potential energy at the top of the pendulum's swing (20 J) must be equal to the kinetic energy at the bottom of its swing.

We can use the formula for kinetic energy:
Kinetic energy = 1/2 * mass * velocity^2

Since the pendulum's mass is given as 0.8 kg, we just need to solve for the velocity at the bottom of its swing.
20 J = 1/2 * 0.8 kg * v^2

Solving for v, we get:

v = √(40/0.8)
v ≈ 8.94 m/s

Now that we know the velocity at the bottom of the pendulum's swing, we can calculate its kinetic energy:

Kinetic energy = 1/2 * 0.8 kg * (8.94 m/s)^2
Kinetic energy ≈ 32 J

Therefore, the kinetic energy at the bottom of the pendulum's swing is approximately 32 joules.

The acceleration due to gravity on the moon is 1/6 that on Earth. A 55 kg astronaut would weigh 91.7 N on Earth and 15.3 N on the moon.

The weight of an object is determined by its mass and the acceleration due to gravity. On Earth, the acceleration due to gravity is approximately 9.8 m/s^2, while on the moon it is 1/6 of that, or approximately 1.6 m/s^2. To find the weight of the astronaut on the moon, we can use the formula weight = mass x acceleration due to gravity. Thus, on Earth, the astronaut would weigh 55 kg x 9.8 m/s^2 = 539 N.

On the moon, the astronaut would weigh 55 kg x 1.6 m/s^2 = 88 N. However, weight is usually measured in newtons (N), not kilograms (kg). To convert the weight in kilograms to newtons, we can multiply the weight in kg by 9.8 m/s^2 (on Earth) or 1.6 m/s^2 (on the moon). Therefore, the astronaut would weigh 91.7 N on Earth and 15.3 N on the moon.
