Using the “On the Highway” distance time graph, what is the average velocity of the car? (use slope = rise/ run OR v = d/t)

Reading the graph, you get 300 km in 4 hours.

Givens

  • d = 300 km
  • t = 4 hours

Formula

v = d/t

Solution

v = 300/4 = 75 km/hour which is the slope.

Comment

Any point that you can read accurately will give you the same answer. Since the point are not that readable, you can estimate one of them

Try

t = 6 hours

d = 450 km An estimate. It looks to be 1/2 way between 400 and 500 km when t = 6 hours.

v = ??

v = 450/6

v = 75 miles / hour  << Answer

A radio frequency identification application would most likely interface with a (an):_________
Irina-Kira [14]

A radio frequency identification application would most likely interface with an Operational Data Store.

The Operations Data Store (ODS) is a central database that provides the latest data snapshots from multiple transaction systems for operational reporting.

It allows organizations to combine data in its original format from various sources into a single destination to provide business reporting.

ODS contains integrated updates from operational sources and supports business intelligence (BI) tools to facilitate tactical decision making.

For example, an administrator can configure ODS to pull weekly batches of data from a billing application that is rarely updated, importing individual transaction records as they occur in the sales database(thanks to these database triggers), then combine the two into new relational tables.

As a result, querying and reporting on operational data in ODS comes with the assurance that these integrated tables contain the latest and most relevant snapshots of the business.

Three conducting plates, each of area A, are connected as shown.
Shkiper50 [21]
You have effectively got two capacitors in parallel. The effective capacitance is just the sum of the two. 
Cequiv = ε₀A/d₁ + ε₀A/d₂ Take these over a common denominator (d₁d₂) 
Cequiv = ε₀d₂A + ε₀d₁A / (d₁d₂) Cequiv = ε₀A( (d₁ + d₂) / (d₁d₂) ) 
B) It's tempting to just wave your arms and say that when d₁ or d₂ tends to zero C -> ∞, so the minimum will occur in the middle, where d₁ = d₂ 
But I suppose we ought to kick that idea around a bit. 
(d₁ + d₂) is effectively a constant. It's the distance between the two outer plates. Call it D. 
C = ε₀AD / d₁d₂ We can also say: d₂ = D - d₁ C = ε₀AD / d₁(D - d₁) C = ε₀AD / d₁D - d₁² 
Differentiate with respect to d₁ 
dC/dd₁ = -ε₀AD(D - 2d₁) / (d₁D - d₁²)² {d2C/dd₁² is positive so it will give us a minimum} For max or min equate to zero. 
-ε₀AD(D - 2d₁) / (d₁D - d₁²)² = 0 -ε₀AD(D - 2d₁) = 0 ε₀, A, and D are all non-zero, so (D - 2d₁) = 0 d₁ = ½D 
In other words when the middle plate is halfway between the two outer plates, (quelle surprise) so that 
d₁ = d₂ = ½D so 
Cmin = ε₀AD / (½D)² Cmin = 4ε₀A / D Cmin = 4ε₀A / (d₁ + d₂)

Water is traveling through a horizontal pipe with a speed of 1.7 m/s and at a pressure of 205 kPa. This pipe is reduced to a new
Arturiano [62]

Answer:

The velocity is  v_2 =  6.8 \ m/s

The pressure is  P_2 =  204978 Pa

Explanation:

From the question we are told that

 The speed at which water is travelling through is  v = 1.7 \ m/s

  The pressure is  P_1 = 205  k  Pa =  205 *10^{3} \ Pa

   The diameter of the new pipe is d =  \frac{D}{2}

Where D is the diameter of first pipe

   

According to the principal of continuity we have that

       A_1 v_1 =  A_2 v_2    

Now  A_1 is the area of the first pipe which is mathematically represented as

       A_1 = \pi  \frac{D^2}{4}

and  A_2 is the area of the second pipe which is mathematically represented as  

       A_2 = \pi  \frac{d^2}{4}

Recall   d =  \frac{D}{2}

        A_2 = \pi  \frac{[ D^2]}{4 *4}

        A_2 = \frac{A_1}{4}

So    A_1 v_1 =  \frac{A_1}{4}  v_2

substituting value

        1.7 =  \frac{1}{4}  * v_2    

        v_2 =  4 * 1.7    

       v_2 =  6.8 \ m/s

   

According to Bernoulli's equation  we have that

     P_1 + \rho \frac{v_1 ^2}{2} =  P_2 + \rho \frac{v_2 ^2}{2}

substituting values

     205 *10^{3 }+ \frac{1.7 ^2}{2} =  P_2 +  \frac{6.8 ^2}{2}

     P_2 =  204978 Pa
