Answer:

YES

Explanation:

If we connect batteries in series then the output voltage is the sum of the individual voltage of each battery i.e if you connect three 12 volts batteries in series then their output voltage will be 12+12+12=36 volts, but the current rating of the batteries in series will be same of the individual battery rating in 'mah'.

But when we connect the batteries in parallel their voltage is not added but their current rating in mah is addition of their individual rating.

So, If you want 24 volts from three 12 volts battery then you can connect two of them in series and the other one in parallel with them this will give 24 volts and the current will be addition of the two series batteries and the third which is in parallel with them. You can use this configuration if current value is not a big factor.

We need to design a logic circuit for interchanging two logic signals. The system has three inputs I1I1, I2I2, and SS as well as

Salsk061 [2.6K]

Explanation:

Inputs and Outputs:

There are 3 inputs = I₁, I₂, and S

There are 2 outputs = O₁ and O₂

The given problem is solved in three major steps:

Step 1: Construct the Truth Table

Step 2: Obtain the logic equations using Karnaugh map

Step 3: Draw the logic circuit

Step 1: Construct the Truth Table

The given logic is

When S = 0 then O₁ = I₁ and O₂ = I₂

When S = 1 then O₁ = I₂ and O₂ = I₁

I₁ | I₂ | S | O₁ | O₂

0 | 0 | 0 | 0 | 0

0 | 0 | 1 | 0 | 0

0 | 1 | 0 | 0 | 1

0 | 1 | 1 | 1 | 0

1 | 0 | 0 | 1 | 0

1 | 0 | 1 | 0 | 1

1 | 1 | 0 | 1 | 1

1 | 1 | 1 | 1 | 1

Step 2: Obtain the logic equations using Karnaugh map

Please refer to the attached diagram where Karnaugh map is set up.

The minimal SOP representation for output O₁

$O_1 = I_1 \bar{S} + I_2 S$

The minimal SOP representation for output O₂

$O_2 = I_2 \bar{S} + I_1 S$

Step 3: Draw the logic circuit

Please refer to the attached diagram where the circuit has been drawn.

For Laminar flow conditions, what size pipe will deliver 90 gpm of medium oil at 40°F (υ = 6.55 * 10^‐5)?

MrRissso [65]

Answer:

1.693 feet

Explanation:

We have given Q = 90 gpm

We know that 1 cubic feet per second = 443.833 gpm

So 90 gpm will be equal to $\frac{90}{443.833}=0.202\frac{ft^3}{sec}$

Let d is the diameter of the pipe then $V_{avg}=\frac{Q}{A}=\frac{0.2}{\frac{\pi }{4}d^2}=\frac{0.255}{d^2}$

We know that for pipe flow critical Reynolds number =2300

So $\frac{V_{avg}d}{\nu }=2300$

Value of $\nu$ is $6.55\times 10^{-5}$ given in question

So $\frac{0.255\times d}{d^2\times 6.5\times 10^{-5}}=2300$

d=1.693 feet

You are an engineer working in a auto crash test lab. Some members of your team have raised objections against the use of cadave

Nikolay [14]

Answer: Application.

Explanation:

The question on wether to contine the use of cadavers in the lab for test is being centered around its application. Cadaver which is same as a corpse or dead body is used in crash site during automobil test in lab, some of this cadavers are been disrespected with their applications in the automobile industries because many didn’t consent to be used in those experiments or test.

Explain with examples:<br> What are the reasons of a successful and unsuccessful software project?

malfutka [58]

Answer: Not Enough Time

Often, the deadline date is decided before the project starts and is non-negotiable. This deadline results in a headlong rush to get started on the assumption, the sooner you begin coding, the sooner you'll finish.

A rush to start coding is almost always the wrong approach. It is important to spend the time to create a good design. Not having a good design leads to continuing changes throughout the development phase. When this happens, time and budget are consumed at a rapid rate.

Solution: Make time to create a good design. Don't be tempted to jump straight in and begin coding. Assign time to this task and the rest of the project will run much better. It will improve your reputation when you deliver something that fulfils the customers' expectations and works the first time correctly.
