<u>Answer:</u>

<em><u>a. slow down</u></em>

<u>Explanation:</u>

To properly answer this question, you must understand what hydroplaning is. Hydroplaning is essentially when a car begins to slide on a wet road and the driver cannot control the vehicle. This happens because of an overflow in water on the road which causes the tires to begin to skim on the surface of the water. Having a proper amount of tire tread, typically 5/23 inches deep or above, will reduce chances of a car hydroplaning on a wet surface.

<em>* note:</em>

<em>if you would like a better understanding of what hydroplaning looks like, there are videos on the internet you could watch that show real life footage of what it looks like when cars hydroplane. I recommend searching up 'car hydroplaning.'</em>

<em />

Now that we fully understand the question, let's examine each option individually and determine what is the best thing to do to prevent hydroplaning.

<em><u>option a</u></em>

<em><u>slow down</u></em>

<em><u /></em>

When a persons car begins to hydroplane, it may be going so fast that it becomes difficult to control. Therefore, slowing down to reduce the speed of the car would be your best bet to try and regain control.

<u><em>option b</em></u>

<u><em>speed up</em></u>

<u><em /></u>

Stepping on the accelerator will increase the speed of the car which will cause it continue to skim on the surface of the water. This may cause the driver to lose even more control of the vehicle.

<u><em>option c</em></u>

<u><em>deflate your tires</em></u>

<u><em /></u>

Deflating your tires would not be a very reliable option, as it can make you lose control even more. It is also not a guarantee that you would even be able to deflate your tires.

<u><em>option d</em></u>

<u><em>use cruise control</em></u>

<u><em /></u>

If you put your car on cruise control it can punctually cause you to lose more control and cause your car to increase more speed.

Now that we have gone through each option individually, we can determine that option a 'slow down' is the best thing to do to prevent hydroplaning.

Volgvan

Answer:

Answer is c Heisenberg's uncertainty principle

Explanation:

According to Heisenberg's uncertainty principle there is always an inherent uncertainty in measuring the position and momentum of a particle simultaneously.

Mathematically

\Delta x\times \Delta \overrightarrow{p}\geq \frac{h}{4\pi }

here 'h' is planck's constant

What effect does air have on the acceleration of aircraft during flight?
scoundrel [369]
The effect would be the altitude of the air, the higher you go up the closer you are to space we’re there’s no oxygen and everything moves slow so when your trying to fly across the world it could feel like your moving slower

In contouring, it is necessary to measure position and not velocity for feedback.
EastWind [94]

Answer:

(1). False, (2). True, (3). False, (4). False, (5). True.

Explanation:

The term ''contouring'' in this question does not have to do with makeup but it has to deal with the measurement of all surfaces in planes. It is a measurement in which the rough and the contours are being measured. So, let us check each questions again.

(1). In contouring, it is necessary to measure position and not velocity for feedback.

ANSWER : b =>False. IT IS NECESSARY TO MEASURE BOTH FOR FEEDBACK.

(2). In contouring during 2-axis NC machining, the two axes are moved at the same speed to achieve the desired contour.

ANSWER: a=> True.

(3). Job shop is another term for process layout.

ANSWER: b => False

JOB SHOP IS A FLEXIBLE PROCESS THAT IS BEING USED during manufacturing process and are meant for job Production. PROCESS LAYOUT is used in increasing Efficiency.

(4). Airplanes are normally produced using group technology or cellular layout.

ANSWER: b => False.

(5). In manufacturing, value-creating time is greater than takt time.

ANSWER: a => True.

An escalator handles a steady load of 26 people per minute in elevating them from the first to the second floor through a vertic
photoshop1234 [79]

Answer:

\eta = 70.711\,\%

Explanation:

The power needed to make the escalator working is obtained by means of the Work-Energy Theorem:

\dot W  = \dot U_{g}

\dot W = \dot n \cdot m_{p}\cdot g \cdot \Delta y

\dot W = \left(26\,\frac{persons}{min}\right)\cdot (124\,lbm)\cdot \left(32.174\,\frac{ft}{s^{2}}\right)\cdot \left(\frac{1\,lbf}{32.174\,\frac{lbm\cdot ft}{s^{2}} } \right)\cdot (27.5\,ft)

\dot W = 88660\,\frac{lbf\cdot ft}{min}\,\left(2.687\,hp\right)

The mechanical efficiency of the escalator is:

\eta = \frac{2.687\,hp}{3.8\,hp}\times 100\,\%

\eta = 70.711\,\%
