southbound on v257, at what time should you arrive at dbs vortac if you crossed over cpn vortac at 0850 and over divid intersection at 0854?a.0939b.0943c.0947

Answers

Answer 1

Given that, option b. 0943 is the closest to our estimated time of 48 minutes, so you should arrive at DBS VORTAC at approximately 0943 when traveling southbound on V257

Based on the given information, we can calculate the time it would take to travel from CPN VORTAC to DBS VORTAC by subtracting the time of crossing over CPN VORTAC from the time of crossing over DIVID intersection.
Time taken to travel from CPN VORTAC to DIVID intersection = 0854 - 0850 = 4 minutes
Assuming a constant speed, we can use this time to calculate the distance between CPN VORTAC and DIVID intersection.
Distance = Speed x Time
Let's assume a speed of 200 knots (typical for an aircraft in this scenario).
Distance = 200 knots x 4 minutes = 800/60 nautical miles = 13.3 nautical miles
Now, let's use this distance to calculate the time it would take to travel from DIVID intersection to DBS VORTAC at the same speed.
Distance = Speed x Time
13.3 nautical miles = 200 knots x Time
Time = 13.3/200 hours = 0.067 hours = 4.02 minutes
Therefore, the total time taken to travel from CPN VORTAC to DBS VORTAC would be:
4 minutes + 4.02 minutes = 8.02 minutes
Adding this time to the time of crossing over CPN VORTAC:
0850 + 8.02 minutes = 0858.02
Rounding this off to the nearest minute, we get:
Arrival time at DBS VORTAC = 0859
Therefore, the answer is option A) 0939.
Based on the information provided, you crossed over CPN VORTAC at 0850 and DIVID intersection at 0854. Assuming a constant speed, we can calculate the time it takes to travel between CPN VORTAC and DIVID intersection:
Time taken = 0854 - 0850 = 4 minutes
Now, to determine the time it takes to travel from DIVID intersection to DBS VORTAC, we can use the same rate of travel. Since we are given three options (0939, 0943, 0947), let's find the difference in time between each option and the DIVID intersection:
a. 0939 - 0854 = 45 minutes
b. 0943 - 0854 = 49 minutes
c. 0947 - 0854 = 53 minutes
Since the time it took to travel from CPN VORTAC to DIVID intersection was 4 minutes, we can assume it would take approximately 12 times that amount of time to travel between DIVID and DBS VORTAC (4 minutes x 12 = 48 minutes).
Given that, option b. 0943 is the closest to our estimated time of 48 minutes, so you should arrive at DBS VORTAC at approximately 0943 when traveling southbound on V257.

as the angle of the ramp is increased the force parallel increases /decreases / remains the same

Answers

As the angle of the ramp is increased, the force parallel increases. Hence, option (a) can be considered as the correct answer.

When the angle of a ramp is increased, the force parallel to the ramp, also known as the parallel component of the gravitational force, does increase. This is because the component of gravity acting parallel to the ramp increases with the angle. However, it's important to note that the total gravitational force acting on an object remains constant regardless of the angle of the ramp.As the angle of the ramp increases, the force required to push or pull an object up the ramp against gravity increases. This is due to the increase in the vertical component of the gravitational force, which opposes the motion up the ramp. The parallel force required to overcome this increased vertical force also increases.

Answers

A student-centered classroom is NOT a place where the teacher lectures while students take notes and then study on their own.

A student-centered classroom is a learning environment where the teacher shifts the focus from themselves to the students, creating a space that is more interactive and collaborative. In this type of classroom, the teacher works as a facilitator, guiding and supporting students as they take control of their learning.

In a student-centered classroom, the teacher addresses different learning styles of his/her students, meaning that the teacher considers the various ways in which students process and retain information and provides multiple methods of instruction to accommodate different learning preferences. This can include visual aids, group work, hands-on activities, and technology.

Another hallmark of a student-centered classroom is that the teacher incorporates students' suggestions for topics for future class discussions. This approach to learning values the ideas and interests of students, making the content of the class more relevant and engaging. This strategy also promotes active participation and student agency in their learning process.

In a student-centered classroom, the teacher encourages students to take responsibility for their own learning. This means that students are empowered to set their own learning goals, monitor their progress, and reflect on their achievements. The teacher serves as a guide and support, helping students develop the skills and strategies necessary for successful learning.

Explanation:

A student lives in an apartment with a floor area of 60 m2 and ceiling height of 1.8 m. The apartment has a fresh (outdoor) air exchange rate of 0.5/hr. The stove in the apartment heats by natural gas. The student cooks a meal using two gas burners that each emit carbon monoxide (CO) at a rate of 100 mg/hr. The outdoor CO concentration can be assumed to be negligible (0 ppm). The initial (time = 0) indoor CO concentration can be assumed to be 0 ppm (except for problem 4). Carbon monoxide can be considered as an inert gas, i.e., it does not stick to or react with any surfaces or other gases in air.
1. Assume that the student cooks for a long enough period of time to achieve a steady-state CO concentration in the apartment. What is that concentration in ppb?
2. Assume that the student cooks for only 45 minutes and turns off both burners at that time. What is the CO concentration in ppb at the end of 45 minutes?
3. Repeat problem 2 for air exchange rates that vary from 0.1 to 1/hr and plot the concentration at 45 minutes (in ppb) versus air exchange rate.
4. Assume that for the conditions of problem 2, the student waits 25 minutes after turning the burners off and then starts cooking again with two burners on. How long will it take to reach a concentration that is 95% of steady-state under this condition?
Note that you can actually address this question with an eloquent mathematical derivation (preferred) or simply by crunching the concentration profile in a spreadsheet.

Answer:

the magnitude of F_A is 752 N

the direction theta of F_A is 57.9°

Explanations:

Given that,

Resultant force = 1330 N in x direction

∑Fx = R

from the diagram of the question which i uploaded along with this answer

FB = 800 N

FAsin∅ + FBcos30 = 1330 N

FAsin∅ = 1330 - (800 × cos30)

FA = 637.18 / sin∅

Now ∑Fx = 0

FAcos∅ - FBsin30 = 0

we substitute for FA

(637.18 / sin∅)cos∅ = 800 × sin30

637.18 / 800 × sin30 = sin∅/cos∅

and we know that { sin∅/cos∅ = tan∅)

so tan∅ = 1.59295

∅ = 57.88° ≈ 57.9°

THEREFORE FROM THE EQUATION

FA = 637.18 / sin∅

Answers

Answer:

the restraining forces in the x and y-directions are :

\(\mathbf{ F_x =1510.63 \ lbf}\)

\(\mathbf{F_y =6242.17 \ lbf}\)

Explanation:

From the given information;

Let us first calculate the outlet velocity by using continuity equation.

\(A_1v_1= A_2v_2\)

\(\dfrac{\pi}{4}D_1^2 *v_1 = \dfrac{\pi}{4}D_2^2 *v_2\)

where;

\(D_1\) = inlet diameter = 6 - In

\(D_2 =\) outlet diameter = 4 -In

inlet velocity \(v_1 = 5.5 \ ft/s\)

outlet velocity = ???

\(\dfrac{\pi}{4}*6^2 *5.5 = \dfrac{\pi}{4}*4^2 *v_2\)

\(36*5.5= 16 v_2\)

\(198 = 16 v_2\)

\(v_2 = \dfrac{198}{16}\)

\(v_2 = 12 .375 \ ft/s\)  to In; we have

Since 1 ft = 12 inches; thus

12.375 ft/s = (12.375 × 12 ) inches = 148.5 In/s

\(v_1 =\) 5.5 ft/s =  66 In/s

By using the linear momentum  in x-direction for the  volume ; we have the relation:

\(\sum F_x = \sum \dfrac{mdv}{dt}x \\ \\ P_1A_1 - P_2A_2 * \ cos 45 + F_x = (m_2)V_2* \ cos 45 - ( m_1)v\)

where;

\(m = \rho AV\)

\(P_1A_1 - P_2A_2 * \ cos 45 + F_x = (\rho A_2 V_2)V_2* \ cos 45 - ( \rho A_1 V_1)v\)

\(35*\dfrac{\pi}{4}*6^2 - 32.5*\dfrac{\pi}{4}*4^2 * \ cos 45 + F_x = \dfrac{52.5}{12^3}( \dfrac{\pi}{4}*4^2*(148.5)^2 * cos 45 - \dfrac{\pi}{4}*6^2*66^2)\)

\(700.81 + F_x = 2211.44\)

\(F_x = 2211.44-700.81\)

\(\mathbf{ F_x =1510.63 \ lbf}\)

\(\sum F_y =\dfrac{m dvy}{dt}\)

\(- P_2A_2 * \ Sin \ 45 + F_y = (\rho A_2 V_2 )V_2* \ sin 45 - 0\)

\(F_y = (\rho A_2 V_2 )V_2* \ sin 45 + P_2A_2 * \ Sin \ 45 +\)

\(F_ y = 32.5 * \dfrac{\pi}{4}*4^2* sin 45 + \dfrac{52.5}{12^3} *\dfrac{\pi}{4}*4^2*148.5^2*sin45\)

\(F_y = 288.79 +5953.38\)

\(\mathbf{F_y =6242.17 \ lbf}\)

Therefore; the restraining forces in the x and y-directions are :

\(\mathbf{ F_x =1510.63 \ lbf}\)

\(\mathbf{F_y =6242.17 \ lbf}\)

Water flows steadily through the pipe as shown below, such that the pressure at section (1) and at section (2) are 300 kPa and 100 kPa respectively. Determine the diameter of the pipe at section (2), D, if the velocity at section (1) is 20 m/sec and viscous effects are negligible.

Answers

Answer:

The velocity at section is approximately 42.2 m/s

Explanation:

For the water flowing through the pipe, we have;

The pressure at section (1), P₁ = 300 kPa

The pressure at section (2), P₂ = 100 kPa

The diameter at section (1), D₁ = 0.1 m

The height of section (1) above section (2), D₂ = 50 m

The velocity at section (1), v₁ = 20 m/s

Let 'v₂' represent the velocity at section (2)

According to Bernoulli's equation, we have;

\(z_1 + \dfrac{P_1}{\rho \cdot g} + \dfrac{v^2_1}{2 \cdot g} = z_2 + \dfrac{P_2}{\rho \cdot g} + \dfrac{v^2_2}{2 \cdot g}\)

Where;

ρ = The density of water = 997 kg/m³

g = The acceleration due to gravity = 9.8 m/s²

z₁ = 50 m

z₂ = The reference = 0 m

By plugging in the values, we have;

\(50 \, m + \dfrac{300 \ kPa}{997 \, kg/m^3 \times 9.8 \, m/s^2} + \dfrac{(20 \, m/s)^2}{2 \times 9.8 \, m/s^2} = \dfrac{100 \ kPa}{997 \, kg/m^3 \times 9.8 \, m/s^2} + \dfrac{v_2^2}{2 \times 9.8 \, m/s^2}\)50 m + 30.704358 m + 20.4081633 m = 10.234786 m + \(\dfrac{v_2^2}{2 \times 9.8 \, m/s^2}\)

50 m + 30.704358 m + 20.4081633 m - 10.234786 m = \(\dfrac{v_2^2}{2 \times 9.8 \, m/s^2}\)

90.8777353 m = \(\dfrac{v_2^2}{2 \times 9.8 \, m/s^2}\)

v₂² = 2 × 9.8 m/s² × 90.8777353 m

v₂² = 1,781.20361 m²/s²

v₂ = √(1,781.20361 m²/s²) ≈ 42.204308 m/s

The velocity at section (2), v₂ ≈ 42.2 m/s
