The given triangular waveform with 50 Hz frequency and 1 V peak is to be converted into a TTL-compatible pulse waveform with fundamental frequency 50 Hz. TTL-compatible pulse waveform has high and low voltage levels of 5 V and 0 V respectively.

The basic idea of conversion is to compare the input triangular waveform with a reference voltage level of 2.5 V (halfway between 5 V and 0 V) and create a pulse waveform such that output is high (5 V) when the input waveform is above 2.5 V and low (0 V) when the input waveform is below 2.5 V.

Here, we can use a simple NAND gate.The logic gate will produce a high output (5 V) only when both its inputs are low (0 V). Therefore, we can connect the comparator output to one input of the NAND gate and a 5 V source to the other input of the NAND gate. This will give a high output when the input waveform is below 2.5 V and low output when the input waveform is above 2.5 V. Thus, we will get a TTL-compatible pulse waveform.The circuit diagram is as shown below:And the input-output waveforms are shown below:

Therefore, we have successfully designed a circuit that can convert a 50 Hz triangular wave with 1V peak into a TTL-compatible pulse wave with a fundamental frequency of 50Hz.

The specific impulse of this turbojet engine is 3273 seconds.

The specific impulse of a turbojet engine can be found using the equation:

Specific Impulse = 1 / (TSFC x g)

Where TSFC is the Thrust Specific Fuel Consumption and g is the acceleration due to gravity (9.81 m/s^2).

Given that the TSFC for this turbojet engine is 1.1 h^-1, we can plug this value into the equation and solve for the specific impulse:

Specific Impulse = 1 / (1.1 h⁻¹ x 9.81 m/s²)

Specific Impulse = 1 / (10.791 h⁻¹ m/s²)

Specific Impulse = 0.0926 h m/s²

Answer:

The distance from rest to takeoff is 6116 meters, and the time from rest to takeoff is 138.9 seconds.

Explanation:

To calculate the distance and time from rest to takeoff for a jet transport with a constant acceleration of 0.4g, we can use the equations of motion for constant acceleration. The equations for distance and time are:

Distance: s = v0t + 0.5at^2

Time: t = (v - v0)/a

Where s is the distance, v0 is the initial velocity, t is the time, a is the acceleration, and v is the final velocity. In this case, we are given that the initial velocity is 0 (since the aircraft is at rest), the acceleration is 0.4g, and the final velocity is 200 km/h.

To convert the final velocity to meters per second, we need to first convert the velocity from kilometers per hour to meters per second. One kilometer is equal to 1000 meters, and one hour is equal to 3600 seconds, so 200 km/h is equal to 200 * 1000 / 3600 = 55.56 m/s.

We can then plug these values into the equations of motion to calculate the distance and time from rest to takeoff:

Distance: s = 0 * t + 0.5 * 0.4g * t^2

s = 0.2g * t^2

Time: t = (v - v0)/a

t = (55.56 - 0) / 0.4g

t = 138.9 seconds

Therefore, the distance from rest to takeoff is 0.2g * 138.9^2 = 6116 meters, and the time from rest to takeoff is 138.9 seconds.

The question asks for the lowest possible elevation of the bottom of the overpass to ensure sufficient stopping sight distance at 60 mi/hr. Stopping sight distance is the distance required for a driver to bring their vehicle to a complete stop in an emergency.
To determine the stopping sight distance, we can use the following formula:

Stopping Sight Distance = Perception Distance + Reaction Distance + Braking Distance

Perception distance can be calculated as follows:

Perception Distance = 1.47 (t + 1.5V)

where t is the perception-reaction time (1.5 seconds) and V is the design speed (60 mi/hr).

Perception Distance = 1.47 (1.5 + 1.5 x 60) = 220.5 ft

Reaction distance can be calculated as follows:

Reaction Distance = V x t

Reaction Distance = 60 x 1.5 = 90 ft

Braking distance can be calculated as follows:

Braking Distance = (V² / 30f) + (V/2g)(a + f)

where f is the coefficient of friction between the tires and the road surface, g is the acceleration due to gravity (32.2 ft/s²), and a is the grade.

Since the initial grade is -3.0%, we can assume that the entire vertical curve has a grade of -3.0%. Therefore, a = -3.0%.

The coefficient of friction depends on several factors such as the condition of the road surface, the weather conditions, and the type of tires. A typical value for the coefficient of friction for dry pavement is 0.7.

Braking Distance = (60² / (30 x 0.7)) + (60/2 x 32.2)(-0.03 + 0.7)

Braking Distance = 410.96 + 180.18 = 591.14 ft

Therefore, the stopping sight distance is:

Stopping Sight Distance = Perception Distance + Reaction Distance + Braking Distance

Stopping Sight Distance = 220.5 + 90 + 591.14 = 901.64 ft

To ensure sufficient stopping sight distance, the driver must be able to see at least 901.64 ft ahead of their vehicle. This means that the lowest possible elevation of the bottom of the overpass should be such that the vertical distance from the driver's eye height (5 ft) to the overpass is greater than or equal to 901.64 ft.

Let h be the height of the overpass above the PVI. Then the vertical distance from the driver's eye height to the overpass is h - 5 ft.

h - 5 ft ≥ 901.64 ft

h ≥ 906.64 ft

Therefore, the lowest possible elevation of the bottom of the overpass should be 906.64 ft above the PVI.

It is proved from the below that the temperature of the egg varies from the shell to the center of the egg.

Using the 2-dimensional finite element method, we will need to find the Biot number of the system by using the formula:

\(\mathbf{Bi = \dfrac{h_c r_o}{k} }\)

According to the Heisler chart, the curves in the graph represent a range of values for the inverse of the Biot number,

where;

\(\mathbf{Bi = \dfrac{h_c r_o}{k} }\)

here;

By developing nodes based on assumptions;

\(\mathbf{Bi = \dfrac{1700 \times 0.025}{0.682} }\)

Bi = 62.32

The inverse of Biot number is:

\(\mathbf{=\dfrac{1}{Bi}}\)

\(\mathbf{=\dfrac{1}{62.32}}\)

= 0.016

Similarly, the Fourier number \(\mathbf{F_o}}\) is calculated by using the expression;

\(\mathbf{F_o = \dfrac{\alpha t }{r_o^2} }\)

\(\mathbf{F_o = \dfrac{k t }{\rho c_pr_o^2} }\)

where;

\(\mathbf{F_o = \dfrac{0.682 \times 15 \times 60 }{958.4 \times 4211 \times 0.025^2} }\)

\(\mathbf{F_o = 0.243}\)

Using the 2-dimensional finite element method, the temperature ratio is:

\(\mathbf{\dfrac{T(0,t) -T_{\infty}}{T_o -T_{\infty}} = 0.1 }\)

T(0,t) = 100 + 0.1(4-100)

T(0,t) = 100 + 0.1(-96)

T(0,t) = 100 - 9.6

T(0, t) = 90.4° C

In hybrid vehicles, the high-voltage (HV) battery pack is typically located in the rear of the vehicle or under the rear seats.

Explanation: The HV battery pack in hybrid vehicles is a key component that stores electrical energy used to power the electric motor or assist the internal combustion engine. Its location in the vehicle is strategically chosen to optimize weight distribution, maximize interior space, and ensure safety.

In many hybrid models, the HV battery pack is positioned in the rear of the vehicle. Placing it in the rear helps to balance the weight distribution between the front and rear axles, improving stability and handling. This location also allows for better utilization of the available space, as the rear of the vehicle is often less occupied compared to the engine compartment or passenger cabin.

In some hybrid vehicles, the HV battery pack may be located under the rear seats. This placement provides additional benefits such as minimizing intrusion into the cargo area, maintaining a low center of gravity for improved stability, and allowing for easy access for maintenance or replacement.

Overall, the specific placement of the HV battery pack may vary depending on the vehicle model and manufacturer's design choices. However, the rear of the vehicle or under the rear seats are common locations chosen for the HV battery pack in hybrid vehicles.

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,\(L^-1 { 2z / (z-1)^2 } = 2n u(n)\)

The frequency (in Hz) of the radiation released by the transition of an electron in a hydrogen atom from the n = 5 level to the n = 3 level is 7.68 x 10¹⁴ Hz

The frequency (in Hz) of the radiation released by the transition of an electron in a hydrogen atom can be calculated using the Rydberg formula:

1/λ = R (1/n1² - 1/n2²)

where λ is the wavelength of the radiation,

R is the Rydberg constant (3.29 x 10¹⁵ Hz), and

n1 and n2 are the initial and final energy levels of the electron in the hydrogen atom, respectively.

For the transition from n=5 to n=3, we have:

1/λ = R (1/3² - 1/5²)

1/λ = R (1/9 - 1/25)

1/λ = R (16/225)

λ = 225/16R

λ = 225/(16 x 3.29 x 10¹⁵)

λ ≈ 390.6 nm

The frequency of the radiation can be obtained by using the speed of light (c) and the wavelength (λ):

c = fλ

f = c/λ

f = (2.998 x 10⁸ m/s)/(390.6 x 10⁻⁹ m)
