a space ship is traveling at 0.7c when a laser beam is turned on that is directed in the direction the ship is traveling. what is the speed of the laser light?

The partial pressures of each species of the equilibrium are

Vapour density = 2.219 g / L

Temperature = 350 K

Total pressure = 0.675 atm

Since volume of flask is constant and the mass is conserved,

Initial mass of NOBr = 2.219 g

1 mol NOBr = 109.92 g

Number of moles of NOBr = 2.219 / 109.92 = 0.02019 mol

Total number of moles at equilibrium is,

\(n_{total}\) = ( 0.02019 - x ) + x + 0.5 x

\(n_{total}\) = 0.02019 + 0.5 x

Acording to ideal gas equation.

\(n_{total}\)  = P V / R T

\(n_{total}\) = ( 0.675 * 1 ) / ( 0.08206 * 350 )

\(n_{total}\) = 0.00662

Partial pressure of NOBr,

P = ( 0.02019 - x ) * 0.675 / ( 0.02019 + 0.5 x )

P = 0.39 atm

Partial pressure of NO,

P = x * 0.675 / ( 0.02019 + 0.5 x )

P = 0.19 atm

Partial pressure of Br₂,

P = 0.5 x * 0.675 / ( 0.02019 + 0.5 x )

P = 0.095 atm

Therefore, the partial pressures of

The given question is incomplete. The complete question is:

A certain amount of NOBr(g) is sealed in a flask, and the temperature is raised to 350 K. The following equilibrium is established:

NOBr(g) ↔ NO(g) + ½ Br2(g)

NOBr(g)↔NO(g)+½Br2(g)

The total pressure in the flask when equilibrium is reached at this temperature is 0.675 atm, and the vapor density is 2.219 g L^-1. Calculate the partial pressure of each species.

Changes in the starting powder size and sprayed particle impact velocity affect the residual stress magnitude in a plasma-sprayed coating.

Plasma spraying is an established thermal spray technology that allows for the deposition of coatings of various materials on different substrates. Plasma-sprayed coatings are used for many applications, ranging from aerospace and energy production to biomedical and automotive industries. Residual stresses are one of the essential parameters affecting the properties and performance of plasma-sprayed coatings.In this context, this essay will discuss the changes in the magnitude of residual stress in a plasma-sprayed coating as a function of changes in the size of the starting powder and the sprayed particle impact velocity.

The residual stresses in a plasma-sprayed coating originate from thermal and mechanical processes taking place during the deposition process. The thermal cycle experienced by the substrate and coating depends on various parameters such as the spray process and material properties. As a result, residual stresses are induced within the coating during the deposition process.When starting powder size is altered, it can significantly influence the residual stresses in the coating. The size of the powder particles can directly affect the particle velocity, energy, and temperature when they interact with the plasma jet.

The powder size distribution affects the surface roughness and porosity of the coating, which further affects the residual stress. Hence, a larger starting powder size tends to increase the residual stress magnitude. In contrast, a smaller starting powder size tends to decrease the residual stress magnitude. Moreover, the sprayed particle impact velocity is another crucial factor that influences the residual stress magnitude.

When the velocity of the particle increases, the coating's residual stress magnitude increases due to the higher kinetic energy transferred to the substrate. In summary, changes in the starting powder size and sprayed particle impact velocity affect the residual stress magnitude in a plasma-sprayed coating.

Answer:

1.667 m/s ^2

Explanation:

we use the formula F=ma

F= 12.5 N

m= 7.5 kg

a=?

F=ma

12.5= 7.5 x a

a= 12.5/7.5

a= 1.667 m/s^2

The given information is as follows: Initial pressure and temperature of air, P1 = 3.5 MPa and T1 = 100°C

Pressure after adiabatic expansion, P2 = 500 kPa

Environmental pressure and temperature, P3 = 101.3 kPa and T3 = 25°C

The adiabatic process is a process in which no heat transfer takes place, and no thermal energy enters or leaves the system. For an adiabatic process, PVγ = constant where P is the pressure, V is the volume, γ is the ratio of specific heats and is equal to CP/CV.CP and CV are the specific heats of the gas at constant pressure and constant volume respectively.

Since there is no heat transfer, PVγ = constant can be written as P1V1γ = P2V2γwhere V1 and V2 are the initial and final volumes of the gas respectively.

Now, from the ideal gas equation PV = nRT,

we have V1 = nRT1/P1 and V2 = nRT2/P2

where n is the number of moles of the gas and R is the universal gas constant.

Substituting the values, P1V1γ = P2V2γ gives T2 = T1(P2/P1)^(γ-1)

Using the values of T1, T3, P1, P3, and γ = 1.4, the temperature change across the valve can be calculated as follows:

T2 = T1(P2/P1)^(γ-1)

= 373.15 K (500/3500)^(1.4-1)

= 260.7 K

The specific irreversibility of the process can be calculated using the following formula:

σ = T0/SΔS

where T0 is the environmental temperature, ΔS is the change in entropy of the system, and S is the total entropy generated during the process.

Since the process is adiabatic, there is no heat transfer, and hence, ΔS = 0.So,

σ = T0/SΔS

= T0/S(0)

= undefined (since division by zero is not possible)Therefore, the specific irreversibility of the process is undefined.

The average speed of the car is 35.6m/s

The average speed is the total distance traveled by the object in a particular time interval. The average speed is a scalar quantity. It is represented by the magnitude and does not have direction. It is measured in meter per second

Therefore average speed = total distance / total time taken

The total distance here is 500+ 500= 1000km = 1×10⁶m

the time taken for the first journey = 500×1000/35= 14285.71 seconds

the time taken for traveling back = 500000/43= 11627.91 seconds

total time taken = 14285.71 + 11627.91 = 25913.62seconds

Answer:

the work done by the worker in pulling the crate is 500 J, and the kinetic energy of the crate at the end of the 10 m distance is 292.13 J.

Explanation:

To solve the problem, we need to first resolve the applied force and the frictional force into their horizontal and vertical components. The horizontal component of the applied force is:

F_h = Fcos(30°) = 50cos(30°) = 43.3 N

The vertical component of the applied force is:

F_v = Fsin(30°) = 50sin(30°) = 25 N

The frictional force is acting in the opposite direction to the applied force, so its horizontal component is:

f_h = -F_f = -20 N

Since the crate is initially at rest, the net force on the crate is equal to the applied force minus the frictional force:

F_net = F_h + f_h = 43.3 - 20 = 23.3 N

The acceleration of the crate is given by Newton's second law:

F_net = ma

where a is the acceleration of the crate. Rearranging this equation, we get:

a = F_net/m = 23.3/30 = 0.78 m/s²

The work done by the worker in pulling the crate a distance of 10 m is given by:

W = Fdcos(θ)

where d is the distance pulled, and θ is the angle between the applied force and the displacement. In this case, θ = 0° since the force is applied horizontally. Therefore, the work done is:

W = Fd = 5010 = 500 J

The kinetic energy of the crate at the end of the 10 m distance is:

K = (1/2)mv²

where v is the final velocity of the crate. We can find v using the equation of motion:

v² = u² + 2as

where u is the initial velocity (zero), s is the displacement (10 m), and a is the acceleration (0.78 m/s²). Therefore:

v² = 0 + 20.7810 = 15.6

v = sqrt(15.6) = 3.95 m/s

Substituting this value of v into the equation for kinetic energy, we get:

K = (1/2)mv² = (1/2)30(3.95)² = 292.13 J

Therefore, the work done by the worker in pulling the crate is 500 J, and the kinetic energy of the crate at the end of the 10 m distance is 292.13 J.

The atomic weight

Explanation:

The property of isotopes that must be different is the atomic weight.

Isotopes are generally referred to as atoms of the same element with the same atomic number (proton number) but different neutron numbers.

Since the atomic weight of an atom is the sum of proton and neutron, atomsof the same element with different number of neutrons will definitely have different atomic weight.

By definition, Weight is a measure of the force of gravity pulling down on an object. it is measured in newtons (N), the common unit for measuring force.

Weight is called the action exerted by the force of gravity on the body.

The mass (amount of matter that a body contains) of an object will always be the same, no matter where it is located. Instead, the weight of the object will vary according to the force of gravity acting on it.

The formula that allows you to calculate the weight of any body is:

P = m×g

where:

Then, the weight of an object is the force of gravity on the object, that is, the weight will vary according to the force of gravity that acts on it. So the correct answer is:

Weight is a measure of the force of gravity pulling down on an object. it is measured in newtons (N), the common unit for measuring force.

To calculate the time required for a person to radiate away the energy gained by eating an ice cream cone, we need to use the Stefan-Boltzmann law, which states that the rate of heat transfer from an object is proportional to the fourth power of its temperature and its surface area.

The formula is given as: Q/t = εσA(\(T^{4}\) - \(T0^{4}\))

where Q is the heat energy gained by eating the ice cream, t is the time taken to radiate it away, ε is the emissivity of the skin, σ is the Stefan-Boltzmann constant, A is the surface area of the skin, T is the skin temperature, and T0 is the temperature of the surroundings.
