Reflection

Explanation:

The specific behavior of light that will be essential to ensure the success of your design is "Reflection". This is because light maze makes use of a mirror and it's the light that is reflected that we see with our eyes. Also, the manner in which light is reflected off objects will affect the colors that are reflected as well.

Therefore, the relative speed at the time of collision is 17.8816 mps

We will use the equation of motion:

v^2 = u^2 + 2as

s = (v^2 - u^2) / 2a

s = (0 - (25)^2) / (2a)

s = 312.5 / a

The distance the Car B travels during the 1.30 seconds when its driver is distracted and does not apply the brakes is gotten as

S = ut + (1/2)at^2

s = (17.8816 mps)(1.30 sec) + (1/2)(-5.4864 m/sec^2)(1.30 sec)^2

s = 11.645 m

The relative speed at the time of collision is:

(40 mph - 0 mph) * 1.60934 kmph * 1000 m/km / 3600 sec/hour = 17.8816 mps

Car B will only travels at 11.645 m   before hitting Car A which is clear indication that Car B will not be able to stop in time and a collision will occur.

Static Friction and Kinetic Friction

Recall from the previous chapter that friction is a force that opposes motion, and is around us all the time. Friction allows us to move, which you have discovered if you have ever tried to walk on ice.

There are different types of friction—kinetic and static. Kinetic friction acts on an object in motion, while static friction acts on an object or system at rest. The maximum static friction is usually greater than the kinetic friction between the objects.

Imagine, for example, trying to slide a heavy crate across a concrete floor. You may push harder and harder on the crate and not move it at all. This means that the static friction responds to what you do—it increases to be equal to and in the opposite direction of your push. But if you finally push hard enough, the crate seems to slip suddenly and starts to move. Once in motion, it is easier to keep it in motion than it was to get it started because the kinetic friction force is less than the static friction force. If you were to add mass to the crate, (for example, by placing a box on top of it) you would need to push even harder to get it started and also to keep it moving. If, on the other hand, you oiled the concrete you would find it easier to get the crate started and keep it going.

Figure 5.33 shows how friction occurs at the interface between two objects. Magnifying these surfaces shows that they are rough on the microscopic level. So when you push to get an object moving (in this case, a crate), you must raise the object until it can skip along with just the tips of the surface hitting, break off the points, or do both. The harder the surfaces are pushed together (such as if another box is placed on the crate), the more force is needed to move them.

1. We can see here that three phase refers to a type of electrical power transmission that uses three alternating current (AC) waveforms that are 120 degrees out of phase with each other. This is different from single-phase power transmission, which uses only one AC waveform.

Voltage, also known as electric potential difference, is a measure of the electrical potential energy per unit of charge in an electrical circuit. It is defined as the amount of work required to move a unit of electric charge between two points in a circuit, typically measured in volts (V).

Three-phase power is needed because it allows for more power to be transmitted over a given amount of wire or cable. With three-phase power, the power is delivered in a more consistent manner, which means that there is less voltage drop over long distances.

2. In order for a three-phase system to be balanced, the three phases must have the same amplitude and be 120 degrees out of phase with each other. The voltage equation of a balanced three-phase voltage source is given by:

Vph = Vline / √3

where Vph is the phase voltage and Vline is the line voltage. The phasor diagram for a balanced three-phase system shows three sinusoidal waveforms that are displaced by 120 degrees from each other.

as this is a vague term that does not specify the make or model of a vehicle.

However, in general, vented disc brakes provide better heat dissipation and are more effective at reducing brake fade compared to solid disc brakes. The vented design allows air to flow through the rotor, which helps to dissipate heat generated during braking. This is especially important in high-performance vehicles or in situations where heavy braking is required, such as during prolonged downhill driving or in emergency stopping scenarios. Vented disc brakes can also be lighter than solid disc brakes, which can improve overall vehicle performance.

Auteurist theory asserts that films are a medium of personal expression, and filmmakers leave a recognizable stylistic signature on their work. According to this theory, the director is considered the primary author or "auteur" of a film, shaping its artistic vision and imbuing it with their unique creative sensibilities. Auteurs have distinct thematic, visual, and narrative characteristics that are consistent across their body of work, allowing audiences and critics to identify their films based on these signatures.

Given the Z-transform of impulse response of a stable LTI system is:

\(h(z) = 2z / (z-1)\)

we have to decompose the above rational Z-transform to partial fractions. This is done by applying the partial fraction decomposition techniques.

\(h(z) = 2z / (z-1) = A / (z-1) + Bz\)

After the multiplication of (z-1) on both sides, we get

\(2z = A + Bz(z = 1) => A = 2z = 2\)

\(B = 2 / (z-1)\) Now, h(z)

\(h(z) = 2 / (z-1) + 2z / (z-1)^2\)

Now, we know the Z-transform of unit impulse function δ(n), which is:

\(Z{δ(n)} = 1\)

the Z-transform of h(n) can be expressed as:\(H(z) = Z{h(n)} = 2 / (z-1) + 2z / (z-1)^2\)Now, applying the inverse Z-transform on H(z), we get the h(n), as follows:

\(h(n) = L^-1 {H(z)} = L^-1 { 2 / (z-1) } + L^-1 { 2z / (z-1)^2 }\)

\(h(n) = 2δ(n) + 2n u(n)\) Where,\(L^-1 { 2 / (z-1) } = 2δ\)(n)and,\(L^-1 { 2z / (z-1)^2 } = 2n u(n)\)

Therefore, the impulse response h(n) for the given Z-transform is 2δ(n) + 2n u(n).

Answer:

Part 1

1) 0.252 kg/s

2) 457.06 K

3) 63.45%

4) 17.96 kJ

5) 44.85%

Part 2

1) 65.92 kJ

2) 57.62 kJ/kg

Explanation:

1) The mass flow rate

The flow velocity is given by the Bernoulli relation;

\(U =\sqrt{ \dfrac{\Delta P}{\rho } }\)

Where:

ΔP = The difference in pressure = 50 - (-2) = 52 kPa

ρ = Density of air = 1.225 kg/m³

\(U =\sqrt{ \dfrac{52,000}{1.225 } } = 206.03 m/s\)

The volume flow rate, V = U × A

Where:

A = Cross sectional area of the of the inlet = 10 cm² = 0.001 m²

Therefore, V = 0.001 × 206.03 = 0.206 m³/s

The mass flow rate = ρ × V = 1.225 × 0.206 = 0.252 kg/s

2) The minimum outlet temperature

P₁v₁/T₁ = P₂v₂/T₂

v₁ = v₂

∴ P₁/T₁ = P₂/T₂

T₂ = P₂T₁/P₁ = 151.325*300/99.325 = 457.06 K

3) The isentropic efficiency no heat loss

h₁ = 300.4 kJ/kg

\(h_{(out \ actual)}\) = 401.3 kJ/kg

\(h_{(out \ isentropic)}\) = 441.9 + (457.06 - 440)/(460 - 440)*(462.3 - 441.9) = 459.30 kJ/kg

The isentropic efficiency, \(\eta _{S}\), is given by the expression;

\(\eta _{S} = \dfrac{h_{in} - h_{(out \ actual)}}{h_{in} -h_{(out \ isentropic)} } = \dfrac{300.4 - 401.3}{300.4 - 459.3} = 0.6345\)

Therefore, the isentropic efficiency, \(\eta _{S}\) in percentage = 63.45%

4) Where there is an heat loss of 30 kJ/kg, we have;

\(h_{(out \ actual \ new)}\)  = \(h_{(out \ actual)}\) - Heat loss = 401.3- 30 = 371.3 kJ/kg

The work done = (371.3 - 300.04)*0.252= 17.96 kJ/s

The new isentropic efficiency is given by the relation;

\(\eta _{S, new} =\dfrac{300.4 - 371.3}{300.4 - 459.3} = 0.4485\)

Therefore, the isentropic efficiency, \(\eta _{S, new}\), in percentage = 44.85%

Part 2

1) Turbine mass flow rate = 0.252 kg/s

From

T₂ = P₂T₁/P₁ = 101.325*800/151.325= 535.67 K

h₁ = 822.2 kJ/kg

\(h_{(out \ actual)}\) = 503.3 kJ/kg

\(h_{(out \ isentropic)}\) = 544.7 + (535.67 - 520)/(540 - 520)*(544.7 - 524.0) = 560.92 kJ/kg

The maximum work, \(W_{max}\), is given by the expression;

\(W_{max}\) = Mass flow rate×(h₁ - \(h_{(out \ actual)}\))

\(W_{max}\) = (822 - 503.3)*0.252 = 65.92 kJ/s

2) The heat lost, \(h_{loss}\), is given by the relation;

\(h_{loss}\) = \(h_{(out \ isentropic)}\)  - \(h_{(out \ actual)}\) = 560.92  - 503.3 = 57.62 kJ/kg.

A symmetrical fault in a power system is a type of fault that results in a short circuit involving all three phases. This could be a three phase short circuit or a three phase to ground fault.

When a fault is symmetrical, fault currents in the phases are symmetrical in that their magnitudes are equal and they are equally spaced by a 120° angle. So, a symmetrical fault with a high value of current in phases may be taken for granted as the norm.
