Explanation:

One of the major effects of heat transfer is temperature change: heating increases the temperature while cooling decreases it. We assume that there is no phase change and that no work is done on or by the system. Experiments show that the transferred heat depends on three factors—the change in temperature, the mass of the system, and the sub

 molecules and atoms. The motion of atoms create heat or thermal energy. The more motion, the more heat. If it has greater mass, greater thermal energy. Lower mass, low thermal energy.

 More mass = More heat that can be transferred.

Explanation:

Answer:

When air resistance acts, acceleration during a fall will be less than g because air resistance affects the motion of the falling objects by slowing it down. Air resistance depends on two important factors - the speed of the object and its surface area. Increasing the surface area of an object decreases its speed.

According to given statement, the velocity of the second hockey puck after the collision is approximately -23 m/s.

To find the velocity of the second hockey puck after the collision, we can use the principle of conservation of momentum. According to this principle, the total momentum before the collision is equal to the total momentum after the collision.

Before the collision, the first hockey puck has a mass of 0.17 kg and is traveling to the right at 15 m/s. The second hockey puck has a mass of 0.11 kg, and we need to find its velocity after the collision.

The momentum of an object is calculated by multiplying its mass by its velocity. So, the momentum of the first hockey puck before the collision is:

Momentum of first hockey puck before collision = mass of first hockey puck x velocity of first hockey puck
Momentum of first hockey puck before collision = 0.17 kg x 15 m/s
Momentum of first hockey puck before collision = 2.55 kg·m/s

Since the first hockey puck comes to rest after the collision, its final momentum is zero:

Momentum of first hockey puck after collision = 0 kg·m/s

According to the principle of conservation of momentum, the total momentum before the collision (2.55 kg·m/s) is equal to the total momentum after the collision (0 kg·m/s). Therefore, we can set up an equation:

Total momentum before collision = Total momentum after collision

(0.17 kg x15 m/s) + (0.11 kg x velocity of second hockey puck) = 0 kg·m/s

Now we can solve for the velocity of the second hockey puck after the collision:

0.17 kg x 15 m/s + 0.11 kg x velocity of second hockey puck = 0 kg·m/s
2.55 kg·m/s + 0.11 kg x velocity of second hockey puck = 0 kg·m/s

To isolate the velocity of the second hockey puck, we can subtract 2.55 kg·m/s from both sides of the equation:

0.11 kg x velocity of second hockey puck = -2.55 kg·m/s

Then, divide both sides of the equation by 0.11 kg to solve for the velocity:

velocity of second hockey puck = -2.55 kg·m/s / 0.11 kg
velocity of second hockey puck ≈ -23.18 m/s

The velocity of the second hockey puck after the collision is approximately -23 m/s.

In chaos theory , the butterfly effect is the sensetive dependence on initial conditions in which a small change in one state of a deterministic nonlinear can result in large difference in a letter state.

Answer:

In the same way that velocity is the rate of change of displacement, acceleration is the rate of change of velocity. In other words, whenever a car increases its velocity, it is said to be accelerating and whenever it is slowing down, it is said to be decelerating.

Acceleration is a measure of how quickly the velocity of an object changes. So, the acceleration is the change in the velocity, divided by the time. ... The units for acceleration are meters per second squared (m/s2).

The length of the one-dimensional box is approximately 1723 nm.

Based on the information provided, we can determine the length of the one-dimensional box using the electron transition and the emitted photon's wavelength.

When an electron transitions from n=2 to n=1, the energy difference is given by the formula:

ΔE = h*c*(1/λ)

Where ΔE is the energy difference, h is Planck's constant (6.626 x 10⁻³⁴ Js), c is the speed of light (3 x 10⁸m/s), and λ is the wavelength (676.3 nm or 6.763 x 10⁻⁷ m).

For a one-dimensional box, the energy levels are given by: E_n = (n² * h²) / (8 * m * L²)

Where E_n is the energy level, n is the quantum number, m is the electron mass (9.11 x 10⁻³¹ kg), and L is the length of the box.

Since we are interested in the energy difference, we can write: ΔE = E₂ - E₁

Now, we can set the energy difference equal to the photon energy:

E₂ - E₁ = h*c*(1/λ)

Substituting the energy levels formula for E₂ and E₁:

(4*h² / (8*m*L²)) - (h² / (8*m*L²)) = h*c*(1/λ)

Solving for L, we get: L = √((3*h²) / (8*m*λ*c))

Plugging in the known values, we calculate: L ≈ 1.723 x 10⁻⁹ m

Converting to nanometers:

L ≈ 1723 nm

The substance will be reduced to 1/16 of A present, that is 1 lb, in 95 hours.

Let the initial amount of A present be X lb. The rate of decomposition of A is proportional to the amount of A present. Therefore, the rate of decomposition = k * X where k is the proportionality constant. We know that 1 lb of A will reduce to 4 lb in 38 hours. So, the rate of decomposition = X/38.

Also, the rate of decomposition = k * X. Comparing both the equations, k = 1/38. Therefore, the rate of decomposition = X/38A substance will reduce to 1/16 of A present i.e., X/16. Using the equation for the rate of decomposition, we get, X/16 = (1/38)*X*(t). Simplifying, we get t = 95 hrs. Hence, the substance will be reduced to 1/16 of A present, that is 1 lb, in 95 hours.

Passenger car requires 21.23 horsepower to travel at a speed of 50-mi/h on an upgrade of 5% with a smooth pavement, given its weight of 4,500-lb and cross-sectional area of 50 square-feet.

The horsepower developed by the passenger car, we need to calculate the force required to overcome the resistance of the car on the upgrade, and then use that force to calculate the power required in horsepower.

\(Force = Weight * Grade + Drag\)

First, we calculate the force required to overcome the resistance of the car on the upgrade:

where:

Weight = 4,500 lb

Grade = 5% = 0.05

Drag = 0.5 * Air Density * Velocity^2 * Coefficient of Drag * Cross-Sectional Area

\(Drag = 0.5 * Air Density * Velocity^2 * Coefficient of Drag * Cross-Sectional Area\)

\(Air Density =\)\(0.075 lb/ft^3\)

\(Velocity = 50 mph\)

\(Coefficient of Drag = 0.35\)

\(Drag =\)\(0.5 * 0.075 * (50/3600)^2 * 0.35 * 50 = 8.53 lb\)

\(Force = 4,500 * 0.05 + 8.53 = 233.53 lb\)

Next, we calculate the power required in horsepower:

\(Power (HP) = Force * Velocity / 550\)

\(Velocity = 50 mph\)

\(Power (HP) = 233.53 * 50 / 550 = 21.23 HP\)

For a given compression ratio, the thermal efficiency of the Otto cycle will be highest when the working fluid has the highest ratio of specific heats. In this case, argon has the highest ratio of specific heats and therefore it will give the highest thermal efficiency.

The thermal efficiency of an Otto cycle is given by:

η = 1 - (1/r)^(γ-1)

where r is the compression ratio and γ is the ratio of specific heats.

The thermal efficiency depends only on the compression ratio and the ratio of specific heats of the working fluid. Therefore, the working fluid itself does not affect the thermal efficiency. However, the ratio of specific heats is different for each of the three fluids:

For air, γ = 1.4

For argon, γ = 1.67

For ethane, γ = 1.25

The thermal efficiency will be highest for ethane as the working fluid.

The thermal efficiency of the ideal Otto cycle is given by:

η = 1 - (1/r)^(γ-1)

where r is the compression ratio and γ is the ratio of specific heats for the working fluid.

For a given compression ratio, the thermal efficiency of the Otto cycle depends on the value of γ, which is different for different working fluids.

For air, γ = 1.4

For argon, γ = 1.67

For ethane, γ = 1.22

Using these values, we can calculate the thermal efficiency for each case and compare them.

Assuming the same compression ratio for all cases, the thermal efficiencies are:

η_air = \(1 - (1/r)^(0.4)\)

η_argon =\(1 - (1/r)^{(0.67)\)

η_ethane = \(1 - (1/r)^{(0.22)\)

To determine which working fluid will give the highest thermal efficiency, we need to compare these values.

Since the exponent in the expression for thermal efficiency is smaller for ethane, it means that it has a higher thermal efficiency than air and argon for the same compression ratio.

The strong nuclear force, leptons do not interact with this force and include particles like electrons and muons.

Fundamental particles are the building blocks of matter and can be grouped into two categories based on their intrinsic properties and interactions with other particles: fermions and bosons. Fermions are the particles that make up matter and are divided into two subcategories: quarks and leptons. Leptons are fundamental particles that do not participate in the strong nuclear force, while quarks are particles that do participate in the strong nuclear force and are always found within hadrons, which are particles made up of quarks.

Hadrons are subdivided into two categories: baryons and mesons. Baryons are hadrons made up of three quarks, while mesons are hadrons made up of one quark and one antiquark. Some examples of baryons include the proton and the neutron, which are both made up of up and down quarks. Mesons include particles like the pion, kaon, and eta meson.

Leptons, on the other hand, are particles that do not interact with the strong nuclear force and include electrons, muons, and taus, as well as their corresponding neutrinos. Electrons are negatively charged particles that orbit the nucleus of atoms, while muons are similar in many ways to electrons, but are about 200 times more massive. Taus are even more massive than muons.

Overall, the categorization of fundamental particles into hadrons and leptons is based on their interactions with other particles, particularly with respect to the strong nuclear force. While hadrons are made up of quarks and are subject to the strong nuclear force, leptons do not interact with this force and include particles like electrons and muons.

Carbon atoms give organic molecules their overall shape; functional group atoms determine the overall chemical behavior of organic molecules.

Carbon atoms are the building blocks of organic molecules, which are molecules that contain carbon atoms bonded to hydrogen atoms. Carbon atoms have four valence electrons, which allows them to form four covalent bonds with other atoms, such as hydrogen, oxygen, nitrogen, and other carbon atoms. This ability to form multiple bonds allows carbon atoms to connect to each other in a variety of ways, creating an almost endless variety of organic molecules with different shapes and properties. Carbon atoms can form single, double or triple bonds with each other and other atoms, which gives rise to different chemical properties and structures of organic molecules. For example, single bonds are relatively weak and allow for rotation around the bond, whereas double and triple bonds are stronger and do not allow for rotation. This difference in bond strength and rotational freedom is the basis for the different types of isomers, compounds with the same chemical formula but different structures and properties. Furthermore, Carbon atoms can also form cyclic structures such as cyclohexane, cyclopentane and aromatic compounds such as benzene and its derivatives. These cyclic structures are planar and have special properties like stability, reactivity and electronic distribution.

Potential energy of the item is given by 2H= mg₂H (h=2H) mg(H/2)/ mg₂H = 1/4, resulting in a ratio of 1:4.

The energy that an item has as a result of being in a gravitational field is known as gravitational potential energy. It is a type of potential energy as it is the energy that an item would release if it moved in response to gravity.

For example, when an object is lifted to a certain height above the ground, it gains gravitational potential energy because it is now further away from the center of the Earth and has the potential to fall back down and release that energy. The amount of gravitational potential energy gained by the object is proportional to its mass, the acceleration due to gravity, and the height above the ground.

As the distance between charged tape and charged rod decreases, the force of interaction between them increases.

The force of interaction between the charged tape and charged rod is governed by Coulomb's Law.

This law states that the force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

So, as the distance between the charged tape and charged rod decreases, the force of interaction increases.

This is because the charges on the objects are now closer to each other, allowing for a stronger attraction or repulsion, depending on the nature of the charges (like charges repel, opposite charges attract).

A mechanical wave is a wave in physics that involves the oscillation of matter and transmits energy across a medium. While waves can travel great distances, the transmission medium—the material—can only move so far.

The oscillating material stays close to its initial equilibrium position as a result. Only medium with elasticity and inertia can form mechanical waves. Transverse, longitudinal, and surface waves are the three different forms of mechanical waves. Water, sound, and seismic waves are a few of the most prevalent types of mechanical waves.
