Answer:

Enthalpy, hsteam = 2663.7 kJ/kg

Volume, Vsteam = 0.3598613 m^3 / kg

Density = 2.67 kg/ m^3

Explanation:

Mass of steam, m = 1 kg

Pressure of the steam, P = 0.5 MN/m^2

Dryness fraction, x = 0.96

At P = 0.5 MPa:

Tsat = 151.831°C

Vf = 0.00109255 m^3 / kg

Vg = 0.37481 m^3 / kg

hf = 640.09 kJ/kg

hg = 2748.1 kJ/kg

hfg = 2108 kJ/kg

The enthalpy can be given by the formula:

hsteam = hf + x * hfg

hsteam = 640.09 + ( 0.96 * 2108)

hsteam = 2663.7 kJ/kg

The volume of the steam can be given as:

Vsteam = Vf + x(Vg - Vf)

Vsteam = 0.00109255 + 0.96(0.37481 - 640.09)

Vsteam = 0.3598613 m^3 / kg

From the steam table, the density of the steam at a pressure of 0.5 MPa is 2.67 kg/ m^3

Answer:

ill try to help you :)

Explanation:

Answer:

So we know that: E = h*(frequency)

but for this equation, we need energy in joules

so since 1eV is 1.6 * \(10^{-19}\)

we will multiply the energy in eV to 1.6 * 10^-19

so energy in joules:

20000 * 1.6 * 10^-19

3.2 * \(10^{-15}\) j

Now, finding the frequency:

3.2 * 10^-15 = 6.6 * \(10^{-34}\) * frequency

frequency = (3.2 * \(10^{-15}\)) / (6.6 * \(10^{-34}\))

frequency = 4.8 * \(10^{18}\) Hz

Finally, finding the wavelength:

we will use a different formula here,

frequency * wavelength = speed of light

wavelength = speed of light / frequency

wavelength = 3 * \(10^{8}\) / 4.8 * \(10^{18}\)

wavelength = 3 * \(10^{-10}\) / 4.8

wavelength = 0.625 * \(10^{-10}\)

wavelength = 6.25 * \(10^{-11}\) m

frequency = 4.8 * \(10^{18}\) Hz

C) Caching can be used to ensure reasonable performance of a remote-service mechanism. It helps reduce latency by temporarily storing frequently used data closer to the client, improving response times and reducing the load on the server.

To ensure reasonable performance of a remote-service mechanism, a combination of techniques may be used. One technique is caching, which involves storing frequently accessed data in a local cache to reduce the need for network communication. Another technique is shared memory, which allows multiple processes to access the same memory space, reducing the need for data transfer over the network.

Direct memory access can also be used, allowing data to be transferred directly between memory locations without involving the CPU, reducing overhead and increasing speed. Shared data is also a viable option, allowing multiple processes to access the same data structures, further reducing network communication. Ultimately, the specific combination of techniques used will depend on the specific requirements and constraints of the remote-service mechanism.

Because I said so.

The length of the string is approximately 0.50 m.

To find the length of the string, we can use the formula T = 2π√(L/g), where T is the period of the oscillations, L is the length of the string, and g is the acceleration due to gravity.
First, we need to find the period of one oscillation. The student found that 10 oscillations take 12.0 s, so the period of one oscillation is 1.2 s (12.0 s ÷ 10).
Next, we can use the formula T = 2π√(L/g) and solve for L. Rearranging the formula, we get L = g(T/2π)^2.
We know that g is approximately 9.81 m/s^2 and T is 1.2 s, so plugging in those values we get:
L = 9.81 m/s^2 × (1.2 s/2π)^2
L ≈ 0.50 m

Answer:

Magnitude of the velocity = 16.82 m/s

Angular direction, θ = 52.41°

Explanation:

As given ,

mass of bullet, m₁= 50g = 0.05 kg

speed of bullet , u₁ = 600 m/s

mass of the block , m₂ = 4 kg

speed of the block before collision , u₂ = 12 m/s

direction , θ = 30°

Now,

Assume that the combined velocity of bullet and block after collision = v

and the direction = θ

Now, from the conservation of momentum in x - direction :

m₁ u₁ + m₂ u₂ = ( m₁ + m₂ ) vₓ

where v = final velocity after collision

u₁ = initial velocity of bullet before collision = 0

m₁ = mass of the bullet before collision = 0.05 kg

u₂  = velocity of block before collision = 12 cos(30° )

m₂ = mass of block before collision

m₁ + m₂ = combined mass of bullet and block after collision = 0.05 + 4

∴ we get

0.05 (0) + 4(12 cos(30° ) ) = ( 0.05 + 4 ) vₓ

⇒ 0 + 4(6√3) = 4.05 vₓ

⇒24√3 = 4.05 vₓ

⇒vₓ = 10.26 m/s

Now, from the conservation of momentum in y - direction :

m₁ u₁ + m₂ u₂ = ( m₁ + m₂ ) \(v_{y}\)

where v = final velocity after collision

u₁= initial velocity of bullet before collision = 600

m₁ = mass of the bullet before collision = 0.05 kg

u₂  = velocity of block before collision = 12 sin(30° )

m₂= mass of block before collision

m₁+ m₂= combined mass of bullet and block after collision = 0.05 + 4

∴ we get

0.05 (600) + 4(12 sin(30° ) ) = ( 0.05 + 4 ) \(v_{y}\)

⇒ 30 + 4(6) = 4.05 \(v_{y}\)

⇒30 +24 = 4.05 \(v_{y}\)

⇒54 = 4.05 \(v_{y}\)

⇒\(v_{y}\) = 13.33 m/s

Now, the magnitude of the velocity = √vₓ² + \(v_{y}\)² = √(10.26)² + (13.33)²

                                                           = √105.26 + 177.68

                                                           = √282.95 = 16.82

The angular direction, θ =  \(tan^{-1}\)(\(\frac{v_{y} }{v_{x} }\)) =  \(tan^{-1}\)(\(\frac{13.33}{10.26}\)) = \(tan^{-1}\)(1.299) = 52.41°

The correct answer is To calculate the discrete settling velocity of a grit particle, we can use the following formula:

\(V_s = (2/9) * (ρ_p - ρ_f) * g * r^2 / η\)

V_s = discrete settling velocity

ρ_p = density of particle

ρ_f = density of fluid

g = acceleration due to gravity

r = radius of particle

η = dynamic viscosity of fluid Given that the radius of the grit particle is 0.05mm and its specific gravity is 2.65, we can calculate its density as:

ρ_p = specific gravity * ρ_water

\(= 2.65 * 1000 kg/m^3= 2650 kg/m^3\)

At a water temperature of 20°C, the dynamic viscosity of water is\(1.004 × 10^-6 m^2/s,\)which we are given.

The density of water at 20°C is approximately \(1000 kg/m^3,\) and the acceleration due to gravity is\(9.81 m/s^2.\)

Substituting these values into the formula, we get:

\(V_s = (2/9) * (2650 - 1000) * 9.81 * (0.05 × 10^-3)^2 / (1.004 × 10^-6)= 0.086 m/s\)(rounded to three decimal places)

Therefore, the discrete settling velocity of the grit particle is approximately 0.086 m/s.

Explanation:

False. Fire extinguishing equipment cannot be frozen according to Ref. 213/91.

According to Ref. 213/91, fire extinguishing equipment cannot be frozen. Fire extinguishers are essential safety devices designed to combat fires effectively. They contain pressurized agents that are specifically formulated to extinguish different types of fires. Freezing temperatures can significantly impair the functionality of fire extinguishers and render them ineffective in emergency situations.

When fire extinguishing equipment freezes, several issues can arise. First, the contents of the extinguisher may expand as they freeze, potentially leading to ruptures or leaks in the container. This can cause the extinguisher to malfunction or become hazardous when used. Second, freezing temperatures can affect the performance of the extinguishing agent itself. Certain agents, such as water-based solutions, can solidify or lose their effectiveness when exposed to extreme cold.

It is crucial to store fire extinguishers in suitable environments that are above freezing temperatures. This ensures that the equipment remains in optimal condition and is ready for immediate use during emergencies. Regular inspections and maintenance are also essential to identify any signs of damage or deterioration that may compromise the functionality of fire extinguishers.
