The rock was launched in the upward direction with an initial velocity of 8.58 m/s.The speed of the rock 4.5 seconds after launch is  35.52 m/s.

Given:

Time after launch (t) = 2.1 s

Rising rate (v) = 12 m/s

(a) By using the equation of motion v = u + at

where,

v denotes the final velocity, u initial velocity, a is the acceleration, and t is the time.

v = u + at

12= u + (9.8) × 2.1 s

u = 12 - (9.8 m/s² × 2.1 s)

u = 12 - 20.58

u = -8.58 m/s

The negative sign indicates that the rock was launched in the upward direction with an initial velocity of 8.58 m/s.

(b) To calculate the speed 4.5 seconds after launch,

v = u + at

v = -8.58 + (9.8) × 4.5 s

v = 35.52 m/s

The speed of the rock 4.5 seconds after launch is  35.52 m/s.

Answer:

Housed in the same building as Vincent van Gogh’s “The Starry Night” and Andy Warhol’s “Campbell’s Soup Cans” is a simple paper coffee cup sleeve. It can be found not in the café at New York’s Museum of Modern Art (MoMA), but rather in the museum’s collections alongside renowned works of art worth millions. But it would be wrong to consider it out of place; the genius of the coffee cup sleeves makes it a million-dollar object as well.

For many, the morning ritual wouldn’t be complete without standing in line at a nearby coffee shop, placing an order with a frazzled cashier managing the A.M. rush and watching the barista pour the coffee, slap a slid on top of the cup and slip a cardboard sleeve over it. It’s a simple and logical ritual, but without that sleeve, what would have happened to our to-go coffee culture? In 2005, MoMA paid tribute to this ingenious design defining the modern American coffee tradition when it acquired a standard coffee cup sleeve for the exhibit “SAFE: Design Takes on Risk,” which featured products that were created to protect. The sleeve takes pride of place at MoMA, alongside Post-It notes, Bic pens and Band-Aids in a collection called “Humble Masterpieces.”

(a) The maximum tensile stress in the standard weight steel pipe is determined to be 16,000 psi.

(b) Assuming an extra-strong pipe, the maximum tensile stress is calculated to be 20,000 psi.

(a) To calculate the maximum tensile stress in the standard weight steel pipe, we need to consider the internal pressure acting on the pipe. The internal pressure is given as 400 psi. The maximum tensile stress can be determined using the formula:

Maximum Tensile Stress = (Internal Pressure * Outside Diameter) / (2 * Wall Thickness)

Substituting the given values into the formula, we get:

Maximum Tensile Stress = (400 psi * 12.75 in.) / (2 * 0.375 in.) = 16,000 psi

Therefore, the maximum tensile stress in the standard weight steel pipe is 16,000 psi.

(b) Similarly, for the extra-strong pipe, we use the same formula but with the given dimensions for the outside diameter and wall thickness. Substituting the values, we get:

Maximum Tensile Stress = (400 psi * 12.75 in.) / (2 * 0.5 in.) = 20,000 psi

Therefore, for the extra-strong pipe, the maximum tensile stress is 20,000 psi.

The potential energy of the 2-kg mass relative to the ground is approximately 80 J.

A sort of energy known as potential energy is one that an object holds as a result of its location or circumstance. It is the energy that is conserved inside a system and has the capacity to be transformed into different types of energy, such as thermal or kinetic energy. Affected by variables like height, distance, and forces operating on it, an object's potential energy relies on where it is in relation to other objects or reference points.

The correct answer is a) 80 J.

The potential energy of an object is given by the formula PE = mgh, where m is the mass of the object, g is the acceleration due to gravity (9.8 \(m/s^2\)), and h is the height of the object above a reference level (in this case, the ground).

Using the given values, we have:

PE = (2 kg)(\(9.8 m/s^2\))(4 m)
PE = 78.4 J

Answer:

It is renewable.

Explanation:

The gravity of the earth is infinite and so it is renewable energy.

Gravitational potential energy is neither renewable nor non-renewable as it is a form of energy that exists due to the position of an object in a gravitational field. It is a type of potential energy that is associated with an object's position in a gravitational field and its mass. The amount of gravitational potential energy an object has depends on its mass, height above the reference level, and the strength of the gravitational field.

Renewable and non-renewable energy sources refer to the sources of energy that are used to generate electricity or power and are consumed over time. Examples of renewable energy sources include solar, wind, and hydropower, while non-renewable energy sources include fossil fuels such as coal, oil, and natural gas.

Therefore, gravitational potential energy is not considered a renewable or non-renewable energy source as it is not a source of energy that is harvested or consumed. Rather, it is a property of an object that can be converted into other forms of energy such as kinetic energy when the object falls or is released from its position in a gravitational field.

The spring is compressed by 0.017 m or 1.7 cm.

The initial kinetic energy of the canister is given by (1/2)mv^2 = (1/2)(0.4 kg)(0.5 m/s)^2 = 0.05 J.

When the canister is stopped by the spring, all of its kinetic energy is transferred to the spring and stored as elastic potential energy.

Thus, the elastic potential energy stored in the spring is 0.05 J.

The elastic potential energy stored in a spring is given by (1/2)kx^2, where k is the spring constant and x is the displacement of the spring from its equilibrium position.

Substituting the values, we get 0.05 J = (1/2)(750 N/m)(x^2), which gives x = sqrt(0.05 J x 2 / 750 N/m) = 0.017 m or 1.7 cm (rounded to two significant figures). Therefore, the spring is compressed by 0.017 m or 1.7 cm.

a) The microscopic total cross section of water is 25.6 barns.

b) The macroscopic total cross section of steam is \(4.25 cm^-1.\)

c)  The macroscopic total cross section of the steam-water mixture is \(1.7 cm^-1.\)

(a) To find the microscopic total cross section of water, we need to sum up the contributions from hydrogen and oxygen:

σ_total = σ_H + σ_O

σ_total = 21.8 b + 3.8 b

σ_total = 25.6 b

Therefore, the microscopic total cross section of water is 25.6 barns.

(b) To find the macroscopic total cross section of steam, we need to multiply the microscopic total cross section of water by the number density of steam molecules. The number density of steam molecules can be found using the ideal gas law:

PV = nRT

where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature. Rearranging this equation to solve for n/V gives:

n/V = P/RT

Since we know the pressure and density of steam, we can solve for the number density:

n/V = P/RT = (\(0.036 g/cm^3\))/(8.31 J/(mol*K) * 373 K) = 1.66 × \(10^19\)molecules/\(cm^3\)

Now we can find the macroscopic total cross section of steam:

Σ = σ_total * (number density of steam molecules)

Σ = 25.6 b * (1.66 × \(10^19\) molecules/\(cm^3\))

Σ = 4.25 \(cm^-1\)

Therefore, the macroscopic total cross section of steam is \(4.25 cm^-1.\)

(c) To find the macroscopic total cross section of the steam-water mixture, we need to take a weighted average of the macroscopic cross sections of water and steam:

Σ_mix = f_water * Σ_water + f_steam * Σ_steam

where f_water and f_steam are the volume fractions of water and steam, respectively. We are given that 40% of the volume is occupied by steam, so f_steam = 0.4 and f_water = 0.6.

Substituting in the values for Σ_water and Σ_steam that we found in parts (a) and (b), we get:

Σ_mix = 0.6 * \(0 cm^-1\) + 0.4 * 4.25 \(cm^-1\)

Σ_mix = 1.7 \(cm^-1\)

Therefore, the macroscopic total cross section of the steam-water mixture is \(1.7 cm^-1.\)

The current flowing through the wires can be calculated as I = V/R = 7.2 kV / 15 Ω = 480 A.

The generator produces 270 kW of electric power at 7.2 kV, and the current of 37.5 A is transmitted through wires with a total resistance of 15 Ω, resulting in a voltage drop of 562.5 V across the transmission wires.

The power produced by the generator is 270 kW at a voltage of 7.2 kV. The current flowing through the wires can be calculated using Ohm's law, which states that V = IR, where V is the voltage, I is the current, and R is the resistance.

Therefore, the power loss in the wires due to resistance can be calculated using the formula P = I^2R, where P is the power loss.

Substituting the values, we get P = (480 A)^2 x 15 Ω = 34.6 kW.

Hence, the power delivered to the remote village will be the difference between the power generated by the generator and the power loss in the wires, which is 270 kW - 34.6 kW = 235.4 kW.

No, the elastic potential energy stored in the pole of a pole vaulter is not the only type of potential energy involved in pole-vaulting.

In pole-vaulting, there are multiple forms of potential energy involved. While the elastic potential energy stored in the pole plays a crucial role, other forms of potential energy include gravitational potential energy and kinetic energy.

1. Elastic Potential Energy: The pole used in pole-vaulting is typically made of flexible materials, such as fiberglass or carbon fiber, which store elastic potential energy when bent or compressed. This stored energy is then released, propelling the vaulter upwards.

2. Gravitational Potential Energy: As the vaulter reaches the highest point of their vault, they have gained gravitational potential energy due to their increased height above the ground. This potential energy is converted into other forms of energy as the vaulter descends.

3. Kinetic Energy: Throughout the vaulting process, the vaulter's body also possesses kinetic energy, which is the energy of motion. The vaulter's initial speed and subsequent acceleration contribute to their kinetic energy, allowing them to gain momentum and clear the bar.

Therefore, while the elastic potential energy stored in the pole is an important component, there are other forms of potential energy involved in pole-vaulting, namely gravitational potential energy and kinetic energy.

When two sources of waves with the same frequency are active, the path length difference must be equal to some whole multiple of the wavelength plus one half the wavelength for the waves to interfere destructively.

This is because in order for two waves to interfere destructively, they must be exactly out of phase with each other. When waves are out of phase, the crest of one wave lines up with the trough of the other, resulting in a cancellation of the waves. This occurs when the path length difference between the two waves is equal to an odd multiple of half wavelengths. For example, if the distance between the two sources is exactly one wavelength, then the waves will interfere constructively, resulting in a stronger wave. However, if the distance is increased to one and a half wavelengths, then the waves will interfere destructively, resulting in a weaker or canceled wave. This pattern repeats for all odd multiples of half wavelengths.
