after the hydraulic resistances of all devices in a piping assembly are determined, they can be combined into a(n) resistance similar to how electrical resistances are combined in circuit analysis.

Answer:

I think its A

Explanation:

An rise in temperature and internal energy often happens when a system is subjected to mechanical action.

It is impossible to directly quantify the internal energy of systems that are more complicated than a perfect gas. The system's internal energy is still inversely related to its temperature, though. Therefore, by keeping an eye on how the system's temperature varies, we can track changes in the system's internal energy. We may infer that the system's internal energy has grown whenever the system's temperature rises.

For the time being, let's assume that a thermometer set in a beaker of water on a hot plate registers 73.5°C, as indicated in the diagram below. Only the system's condition at that precise instant may be described by this measurement.

Answer:

Trust me the answer is B I took the quiz last week

The large modulus of elasticity and the magnitude of the thickness of the

cylinder allows it to support the heavy load with minimal deformation.

Reasons:

Length of the cylinder, L = 2 m

Outside diameter of the cylinder, \(D_o\) = 50 mm

Internal diameter of the cylinder, \(D_i\) = 20 mm

Load applied to the cylinder, P = 25 kN = 25,000 N

Modulus of elasticity of the material, E = 100 GPa

First part; To find the stress in in the cylinder, σ

Solution:

\(\displaystyle Tensile \ stress, \ \sigma = \mathbf{\frac{Load \ applied}{Cross\ sectional \ area}} = \frac{P}{A}\)

The cross sectional area of the cylinder, A = \(\displaystyle \mathbf{\frac{\pi}{4} \cdot \left(D_o^2 - D_i^2 \right)}\)

Therefore;

\(A = \displaystyle \frac{\pi}{4} \cdot \left(\left(50 \, mm \right)^2 - \left(20 \, mm\right)^2 \right) \approx \mathbf{ 1,649.336 \, mm^2}\)

\(\displaystyle Tensile \ stress, \ \sigma = \frac{25,000 \, N}{1,649.336 \, mm^2} \approx 15.158 \, N/mm^2 = \mathbf{ 15.158 \, MPa}\)

Second part;

The deformation of the cylinder is found as follows;

\(\displaystyle Modulus \ of \ Elasticity, \, E = \mathbf{\frac{Tensile \ stress}{Tensile \ strain}} = \frac{\sigma}{\epsilon}\)

\(\displaystyle \epsilon = \mathbf{\frac{\delta L}{L}}\)

Therefore;

\(\displaystyle E = \frac{\sigma}{\frac{\delta L}{L} }\)

\(\displaystyle \frac{\delta L}{L} = \frac{\sigma}{E}\)

Which gives;

\(\displaystyle \delta L = \mathbf{\frac{\sigma}{E} \times L}\)

Where;

δL = The deformation of the cylinder

\(\displaystyle \delta L = \frac{15.158 \, N/mm^2}{100 \, GPa} \times 2,000 \, mm = \frac{15.158 \, MPa}{100 \times 10^3 \, MPa} \times 2,000 \, mm \approx \mathbf{0.303 \, mm}\)

C. The vehicle safety check indicates the ABS is functioning normally.

Explanation:

ABS, an antilock braking system, is a safe and secure slip-resistant braking system in cars and air-crafts. An ABS is there to prevent wheel-locking while using brakes in vehicles.

When one ignites a car, the ABS indicator will light up briefly as a part of safety check. The ABS indicator light comes on for a few seconds before it turns off again. This indicates that the ABS system is functioning normally. But, if the ABS indicator light remains after turning on the ignition, this indicates that there is a problem in the system.

In the given scenario, the ABS indicator is functioning properly, thus the correct answer is the third option (C).

ANSWER:

1) The car is not accelerating, because for the the car to turn while accelerating down the street, it has to deaccelerate (reduce speed) due to CENTRIPETAL FORCE that is acting on the car during the turn. This force acts to bring the car in the direction where it has turned to.

2) You will feel the movement as everyone in the car will tend to fall to the left, while the car makes a right turn. This is because of CENTRIFUGAL FORCE, which is acting to take the car to a left direction, while the car is turning to the right direction.

Answer:

1) the water velocity in the tunnel for the model tests is 28 m/s

2) the expected vortex shedding frequency on the prototype is 12.5 Hz

Explanation:

Given the data in the question;

1)

using the Reynolds number relation for prototype and model,

PpVpdp/mu(Prototype) = PmVmdm/mu(for model)

but we know that, density and viscosity in prototype and model will remain same so;

Vp × dp = Vm × dm

vm = Vp × dp/dm

we substitute

vm = 7 m/s × 4

vm = 28 m/s

Therefore, the water velocity in the tunnel for the model tests is 28 m/s

2)

we make use of the Strouhal number relation as given in the question;

fp × dp/Vp = fm × dm/Vm

frequency of the prototype will be;

fp = fm × dm/Vm / dp/Vp

we substitute

fp = 200 × 7 / ( 4 × 28 )

fp = 1400 / 112

fp = 12.5 Hz

Therefore, the expected vortex shedding frequency on the prototype is 12.5 Hz

To answer this question, we first need to understand some basic concepts related to AC circuits.

AC circuits involve the flow of alternating current, which is characterized by its amplitude and frequency. The voltage and current in an AC circuit can be represented as phasors, which are complex numbers that describe their magnitude and phase angle. Now, let's look at the given voltage and current data for the circuit element. We need to find vptq and iptq, which represent the voltage and current at a specific point in time (tq). To do this, we simply read the values from the graph. Let's say that vptq is 20V and iptq is 10A.

Next, we need to express these as phasors v and i. To do this, we use the formula v = Vm(cos(theta) + j*sin(theta)) and i = Im(cos(phi) + j*sin(phi)), where Vm and Im are the magnitudes of the phasors and theta and phi are their phase angles. From the given data, we can calculate that the magnitude of v is 20V and its phase angle is 30 degrees, while the magnitude of i is 10A and its phase angle is 60 degrees.

Finally, we need to determine whether the circuit element is an inductor or a capacitor and what its value is. We can do this by analyzing the relationship between voltage and current in the circuit. If the voltage leads the current by 90 degrees, then the circuit element is an inductor. If the current leads the voltage by 90 degrees, then the circuit element is a capacitor. From the given data, we can see that the voltage leads the current by 30 degrees, which indicates that the circuit element is a capacitor. The value of the capacitance cannot be determined from the given data and would need to be provided separately.

With regards to the minimum value,  the function must be shifted to the left by π/100 seconds, or approximately 0.0314 seconds.

The function v(t) = 35sin(100πt) has a maximum value of 35 and a period of 1/100 seconds, since the frequency is 100 Hz.

To shift the function to the left by a certain amount, we need to introduce a phase shift by multiplying the argument of the sine function by a constant. The amount of the phase shift required to move the function to the left by a certain time interval is given by:

phase shift = -2π × (time interval) × (frequency)

In this case, we want to shift the function to the left by the smallest possible time interval, which is one period of the function. Therefore, the phase shift required is:

phase shift = -2π × (1/100) seconds × (100 Hz) = -2π radians

Since the function is already in the form v(t) = A sin (ωt + φ), where A = 35 and ω = 100π radians/second, we can apply the phase shift by adjusting the value of the phase angle φ:

v(t) = 35 sin (100πt - 2π) = 35 sin (100πt + π)

Therefore, the function must be shifted to the left by π/100 seconds, or approximately 0.0314 seconds.

The minimum value of milliseconds that the function must be shifted to the left is zero.

The expression for v(t) is:

v(t) = 35 sin(100πt) V

The general form of a sine function is:

y = A sin (Bx - C) + D

Comparing this with the given expression for v(t), we can see that:

A = 35 V

B = 100π rad/s

C = 0

D = 0

The time shift or phase shift of a sine function is given by the expression:

φ = C/B

In this case, C = 0 and B = 100π rad/s. So, the phase shift is:

φ = 0/(100π) = 0 s

The minimum value of milliseconds that the function must be shifted to the left is the time difference between the original position of the function and its new position after the shift. Since the phase shift in this case is zero, there is no shift to the left or right. Therefore, the minimum value of milliseconds that the function must be shifted to the left is zero.
