Chisel edge pencils are used for drawing?

Answer:

\(Bw_1=5.24kHz\)

Explanation:

From the question we are told that:

Induction \(L=8.2uH\)

Resonant Frequencies

 \(F_1=550kHz\\\\\F_2=1050kHz\)

Generally the Bandwidth & Frequency equation  is mathematically given by

 \(\frac{F-1}{Bw_1}=\frac{F_2}{Bw_2}\)

Therefore

 \(Bw_1=\frac{500}{1050}*10\)

 \(Bw_1=5.24kHz\)

Technician A says there is maximum EGR flow only when the vehicle is at a cruising speed with a very light load.

Technician B says instead of an EGR valve many late-model engines use variable valve timing [VVT] to trap some exhaust gases in the combustion chamber.

Who is correct?

Technician A and Technician B have different views regarding EGR (Exhaust Gas Recirculation) flow.

Here,

the discussion will be on EGR's maximum flow and how it works for a vehicle at a cruising speed with a very light load and how it is related to variable valve timing [VVT].

Technician A is partially correct because the maximum EGR flow is not only when the vehicle is at a cruising speed with a very light load.

It is at a vehicle speed of 20-30 mph under light load and mild acceleration conditions that an engine experiences maximum EGR flow.

When the vehicle is at a cruising speed with a very light load, EGR flow may be slightly less, but this is not considered the maximum EGR flow rate.

Technician A is incorrect about the EGR's maximum flow rate.

Technician B is also partially correct.

He claims that late-model engines use variable valve timing [VVT] to trap some exhaust gases in the combustion chamber rather than an EGR valve.

This is because VVT can delay the engine's opening and closing of the exhaust valve to create a vacuum that keeps some exhaust gases in the combustion chamber.

VVT is a system that uses an electronic control module to adjust the valve's lift and timing of the opening and closing to maximize engine performance in various driving conditions.

Technician B is correct that late-model engines use variable valve timing [VVT] to trap some exhaust gases in the combustion chamber.  

Conclusion:

Neither Technician A nor Technician B is completely correct.

Answer:

"192.3 watt" is the right answer.

Explanation:

Given:

Efficient amplifier,

= 65%

or,

= 0.65

Power,

\(P_c=250 \ watt\)

As we know,

⇒ \(P_t=P_c(1+\frac{\mu^2}{2} )\)

By putting the values, we get

        \(=P_c(1+\frac{1}{2} )\)

        \(=1.5 \ P_c\)

Now,

⇒ \(P_i=(P_t-P_c)\)

        \(=1.5 \ P_c-P_c\)

        \(=\frac{P_c}{2}\)

DC input (0.65) will be equal to "\((\frac{P_c}{2} )\)".

hence,

The DC input power will be:

= \(\frac{250}{2}\times \frac{1}{0.65}\)

= \(\frac{125}{0.65}\)

= \(192.3 \ watt\)

In the radio communication system, multipath is the propagation phenomenon that causes diffusion or reflection in multiple different directions of a signal.

Multipath is a propagation mechanism that impacts the propagation of signals in radio communication. Multipath results in the transmission of data to the receiving antenna by two or more paths. Diffusion and reflection are the causes that create multiple paths for the signal to be delivered.

Diffraction occurs when a signal bends around sharp corners; while reflection occurs when a signal impinges on a smooth object. When a signal is received through more than one path because of the diffraction or reflection, it creates phase shifting and interference of the signal.

So, in the question above we are given that the Two Electric field vectors E1 and E2 are perpendicular to each other. Thus, we are going to have the i and the j components for the two Electric Field that is E1 and E2 respectively. That is to say the addition we give us a resultant E which is an arbitrary vector;

E = |E| cos θi + |E| sin θj. -------------------(1).

Therefore, if we make use of the components division rule we will have something like what we have below;

x = |E2|/ |E| cos θ and y = |E1|/|E| sin θ

Explanation:

The program prompts the user to enter the number of elements they want in the array and stores the value in the size variable.

An array arr of integers is dynamically allocated with the size provided by the user. Each element of the array is assigned the value of its subscript.

The showArray function is called with arr and size as arguments to display the values of the array using pointer notation. The function iterates over the elements using a pointer and prints their values.

The reverseArray function is called with arr and size as arguments. It creates a new dynamically allocated array reversedArr and assigns the elements of arr in reverse order.

The showArray function is called again with reversedArr and size to display the values of the reversed array using pointer notation.

Dynamically allocated memory for arr and reversedArr is released using the delete[] operator to avoid memory leaks.

The program first displays the original array using pointer notation and then displays the reversed array.

1) The number of gallons of water lost in a week would be approximately (2.3 m³/s * 604,800 seconds) * (1000 liters/m³) * (0.264172 gallons/liter).

2) The density of the copper sample is approximately 8.32 g/cm³ (347.5 g / 41.8 cm³).

To calculate the number of gallons of water lost in a week, we first need to determine the volume of water that flows through the stream in one week.

Given:

Flow rate of the stream = 2.3 m³/s

To convert the flow rate to the volume of water in one week, we need to convert the time unit from seconds to weeks. There are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day, and 7 days in a week.

1 week = 7 days * 24 hours * 60 minutes * 60 seconds = 604,800 seconds

Volume of water in one week = Flow rate * Time

Volume of water in one week = 2.3 m³/s * 604,800 seconds

Now, let's convert the volume from cubic meters (m³) to gallons.

1 cubic meter = 1000 liters

1 liter = 0.264172 gallons

Volume in gallons = (Volume in cubic meters) * (1000 liters/m³) * (0.264172 gallons/liter)

Finally, we can calculate the number of gallons of water lost in a week.

Volume in gallons = (2.3 m³/s * 604,800 seconds) * (1000 liters/m³) * (0.264172 gallons/liter)

Please note that the flow rate might change due to various factors, but for the given scenario and assumptions, this calculation provides an estimate.

1b) To calculate the density of the copper sample, we'll use the formula:

Density = Mass / Volume

Given:

Mass of the copper sample = 347.5 g

Volume of the copper sample = 41.8 cm³

Density = 347.5 g / 41.8 cm³

=8.32 g/cm³

Explanation:

Answer:

The answer is below

Explanation:

Given:

kg (glass) = 0.78 W/m⋅K, ka (air) = 0.026 W/m⋅K, h1 = 10 W/m2⋅K, h2 = 25 W/m2⋅K, glass length = Lg = 3 mm = 0.003 m, Lo = 3 mm = 0.003 m, La = 12 mm = 0.012 Height = 1.5 m, width = 2.4 m, room temperature = T = 20°C. Therefore:

Total resistance per unit area is given as:

\(R"=\frac{1}{h_1}+\frac{L_g}{k_g}+\frac{L_a}{k_a} +\frac{L_o}{k_g}+\frac{1}{h_2} \\\\R"=\frac{1}{10}+\frac{0.003}{0.78}+\frac{0.012}{0.026} +\frac{0.003}{0.78}+\frac{1}{25} \\\\R"=0.1+0.00385+0.46154+0.00385+0.04\\\\R"=0.60924\ K.m^2/W\)

Area = A = height * width = 1.5 m × 2.4 m = 3.6 m²

The change in temperature = ΔT = 20 °C - (-5 °C) = 25 °C

The rate of heat loss is given as:

\(\dot {Q}=A*\frac{\Delta T}{R"}= 3.6*\frac{25}{0.60924}\\ \\\dot {Q}=147.73\ W\)

The inner surface temperature (Ti) is given as:

\(T_i=T-\frac{\dot {Q}}{A} *\frac{1}{h_1}\\ \\T_i=20-\frac{147.73}{3.6}*\frac{1}{10}=15.9\ ^oC\)

The enthalpy of combustion of methane at 25°C and 1 atm, assuming that the water in the products is in the liquid form, is -802.3 kJ/mol.

The enthalpy of combustion of methane can be calculated using the enthalpy of formation data for methane and water, and the balanced chemical equation for the combustion reaction:

CH4 + 2O2 -> CO2 + 2H2O

The enthalpy change for this reaction can be calculated using Hess's law, which states that the enthalpy change for a reaction is equal to the sum of the enthalpy changes for a series of reactions that add up to the original reaction. In this case, we can use the following reactions:

CH4 + 2O2 -> CO2 + 2H2O (target reaction)

CH4 + 2O2 -> CO2 + 2H2O + 890.3 kJ/mol (enthalpy of formation of CH4)

H2(g) + 1/2O2(g) -> H2O(l) + 285.8 kJ/mol (enthalpy of formation of H2O)

To use Hess's law, we need to reverse the second equation and multiply it by -1, and add it to the first equation to cancel out the H2O on the product side:

CH4 + 2O2 -> CO2 + 2H2O (target reaction)

CH4 + 2O2 -> CO2 + 2H2O + 890.3 kJ/mol (enthalpy of formation of CH4)

H2O(l) -> H2(g) + 1/2O2(g) -285.8 kJ/mol (enthalpy of formation of H2O)

Adding the three equations, we get:

CH4 + 2O2 -> CO2 + 2H2O, ΔH = -802.3 kJ/mol

Therefore, the enthalpy of combustion of methane at 25°C and 1 atm, assuming that the water in the products is in the liquid form, is -802.3 kJ/mol.

AASHTO assumes a deceleration value in calculating stopping sight distance (SSD) of B. 11.2 ft/s^2. This doesn't take any road defects into account.

Angular velocity is a measure of how quickly an object rotates around a fixed axis, expressed in radians per second or degrees per second. It is the rate of change of angular displacement with respect to time.

To find the angular velocity of gear 5 using first order kinematic coefficients, we first need to understand the concept of gears and their motion. Gears are used to transmit power and motion between two shafts. They consist of toothed wheels that interlock and rotate together.

In this case, the centers of gears 4 and 5 are fixed, which means that they rotate together at the same angular velocity. We can use the following equation to find the angular velocity of gear 5:

ω5 = ω4 (r4/r5)

where ω4 is the angular velocity of gear 4, r4 is the radius of gear 4, and r5 is the radius of gear 5.

Since we are given that the centers of gears 4 and 5 are fixed, we can assume that they are rotating at the same angular velocity. Let's call this angular velocity ω. We can then substitute ω for ω4 in the above equation:

ω5 = ω (r4/r5)

Now we just need to know the values of r4 and r5. Let's assume that the radius of gear 4 is 10 cm and the radius of gear 5 is 5 cm. Substituting these values into the equation, we get:

ω5 = ω (10/5)
ω5 = 2ω

So the angular velocity of gear 5 is twice the angular velocity of gears 4 and 5. This means that if gears 4 and 5 are rotating at a speed of 100 rpm, gear 5 will be rotating at a speed of 200 rpm.

In conclusion, to find the angular velocity of gear 5 using first order kinematic coefficients, we can use the equation ω5 = ω4 (r4/r5) and assume that the centers of gears 4 and 5 are fixed. By substituting the values of r4 and r5, we can find the angular velocity of gear 5.

When are resistors in series? Resistors are in series whenever the flow of charge, called the current, must flow through devices sequentially. For example, if current flows through a person holding a screwdriver and into the Earth, then  

R

 in Figure 1(a) could be the resistance of the screwdriver’s shaft,  

R

2

 the resistance of its handle,  

R

3

 the person’s body resistance, and  

R

 the resistance of her shoes.

Figure 2 shows resistors in series connected to a voltage source. It seems reasonable that the total resistance is the sum of the individual resistances, considering that the current has to pass through each resistor in sequence. (This fact would be an advantage to a person wishing to avoid an electrical shock, who could reduce the current by wearing high-resistance rubber-soled shoes. It could be a disadvantage if one of the resistances were a faulty high-resistance cord to an appliance that would reduce the operating current.)

Two electrical circuits are compared. The first one has three resistors, R sub one, R sub two, and R sub three, connected in series with a voltage source V to form a closed circuit. The first circuit is equivalent to the second circuit, which has a single resistor R sub s connected to a voltage source V. Both circuits carry a current I, which starts from the positive end of the voltage source and moves in a clockwise direction around the circuit.

Figure 2. Three resistors connected in series to a battery (left) and the equivalent single or series resistance (right).

To verify that resistances in series do indeed add, let us consider the loss of electrical power, called a voltage drop, in each resistor in Figure 2.

The maximum rating of the motor branch-circuit short-circuit and ground-fault protective device for a 7 1/2-horsepower, 208-volt, 3-phase squirrel-cage induction motor using time-delay fuses is approximately 45 A.

To determine the maximum rating of the motor branch-circuit short-circuit and ground-fault protective device for a 7 1/2-horsepower, 208-volt, 3-phase squirrel-cage induction motor, we can use the National Electrical Code (NEC) guidelines.

Step 1: Calculate Full Load Current (FLA)

The full load current (FLA) of a motor can be calculated using the formula:

\(\mathrm{FLA = \frac{Horsepower \times 746}{\sqrt{3}\times voltages \times efficiency \times power factor } }\)

Since efficiency and power factor are not given, we will assume typical values of 0.85 for efficiency and 0.85 for power factor.

Given:

Horsepower (HP) = 7.5 HP

Voltage = 208 V

Efficiency = 0.85

Power Factor = 0.85

Substitute these values into the formula:

\(\mathrm{FLA = \frac{7.5 \times 746}{\sqrt{3}\times 208 \times 0.85 \times 0.85 } }\)

Step 2: Determine the Maximum Rating:-

According to NEC guidelines, the maximum rating of the protective device can be calculated by multiplying the FLA by a percentage that corresponds to the type of motor and the type of protective device.

For a squirrel-cage induction motor with time-delay fuses, the percentage is typically around 175%.

Maximum Rating = FLA × 175%

Maximum Rating = 25.76A × 1.75 ≈ 45.12A

Rounded to the nearest standard fuse size, the maximum rating of the protective device is 45 A.
