Long Text (essay)

In paragraph of 125 words, explain at least three ways that engineers explore possible solutions in their projects

Answers

Answer:

To do this, engineers often use a technique called "brainstorming." Brainstorming is a team creativity activity that helps you generate a large number of potential solutions to a problem or challenge.

Engineers use the engineering design process when brainstorming solutions to real-life problems; they develop these solutions by testing and redesigning prototypes that work within given constraints.

Engineers will often use reverse-engineering to solve problems. For example, by taking things apart to determine an issue, finding a solution and then putting the object back together again. Engineers know how things work, and so they constantly analyse things and discover how they work.

Answer:

1) Prototyping is the process of experimental testing of samples of design, or model of a product with the possibility of the inclusion of control of parameters in order to determine the workability of a solution.

2) Simulation is the process of creating an imitation of a situation, operation or process which can be used to determine if a particular solution will be able to work as required in the simulated environment of a problem.

3) Calculations are used to find preliminary results of particular situations, their cause and effects based on scientific laws, theories and hypothesis such that the factor of the problem is equated with the available ideas to find the best possible solution.

which of the following best describes the mechanical energy of an object?

Answers

In other words, an object possesses mechanical energy when it has the ability to do work due to its position or motion. Mechanical energy can take the form of either kinetic energy, which is energy due to an object's motion, or potential energy, which is stored energy due to an object's position.

Some examples of mechanical energy are:

Hydro power plantCyclingWrecking balls, etc

What is Mechanical Energy?

This refers to the type of energy that an object or mass possesses based on its motion and can either be potential or kinetic energy.

Therefore, mechanical energy can be represented mathematically as: [tex]E_{mechanical}[/tex] = U + K

Where U= potential energy

K= kinetic energy

How much salt will one teaspoon of water dissolve? Complete this experiment to find out!

Materials:

salt
a small glass jar with a lid
water
measuring spoons
Follow these steps:

Carefully measure out 3 Tablespoons of cold water into the jar.
Now measure out 1/8 teaspoon of salt and put it into the jar with the water. Put the lid on the container and shake it. Keep shaking until the salt is completely dissolved. To determine whether it has completely dissolved, hold the container up to the light and look carefully at the bottom, or open the lid and look into it. If you see little grains of salt there, it is not completely dissolved, so keep shaking until it looks the same each time you look.
If the salt does not dissolve completely after five minutes of vigorous shaking, write this in your notebook and go on to step 4. If the salt dissolves completely, add another 1/8 teaspoon of salt and repeat the process. Repeat over and over, keeping track of how many 1/8 teaspoons you add. Stop when you can’t get the salt to dissolve no matter how hard or long you shake the container.
Record how much salt you were able to dissolve in the 3 Tablespoons of water in the solubility data table.
Repeat steps 1-4, but this time using very warm or hot water. Before you do it, run the jar under hot water to warm it up so the water doesn’t cool off right away. Be sure to use the exact same amounts of water and salt as you did the first time. The only variable should be the temperature of the water.
Record your results, and then compare with your previous results.
Answer the following questions:

Were there any differences in the amount of salt that dissolved in the warm water versus the cold water?

Write a conclusion based on your results, using the terms “temperature” and “solubility.”

Based on your results, answer this question: If the oceans of the earth got warmer from global warming, would the water of the oceans become more or less salty? What do you think the effect of this change in the ocean salinity (saltiness) would be on the plants and animals that live in the ocean?

The final position of a car can be predicted with the following equation: Position = -2.5 (time) + 25 Where is the car’s position at 3.0 seconds? When would the car reach position 0.0 meters?

Answers

Answer:

The car's position at 3.0 seconds is 17.5 meters. The car will reach 0.0 meters at 10 seconds.

Explanation:

You can rewrite the equation as P= -2.5t+25. t=time and P is equal to position; so you will plug in 3.0 seconds into t. The equation will now look like: P = -2.5(3.0)+25

P = -2.5(3.0) + 25

P = -7.5 + 25

P = 17.5 meters

Now, to find when the car reaches 0.0 meters, we will plug that into P since P = position and will solve for t.

P = -2.5t + 25

0.0 = -2.5t + 25

-25                 -25

-25 = -2.5t

-25/-2.5 = -2.5t/-2.5

10 = t

So the car will reach 0.0 meters at 10 seconds.

The main cables of the Golden Gate Bridge are made of numerous smaller cables because by combining several thousand in number of smaller cables, each having a diameter which is approximately the diameter of a pencil, into the required cable diameter dimensions, the flexibility, strength, resistance to cracking, rotation resistance, crushing resistance and fatigue resistance of the main cables are increased, and failure of a few strands in a multi-stranded cable is more likely to be detected before catastrophic failure takes place than in a single cable

The radiator can be described as a heat exchanger used to eliminate heat from the coolant in the cooling system to prevent the vehicle’s engine from overheating. The hot coolant is routed via the radiator, where the coolant exchange heat with the passing air.

The AC Compressor pumps coolant throughout the system and starts the process of the cooling car. The battery saves energy in chemical form so it is released as electricity to run the vehicle’s electrical components.

The front and rear axles are supporting a vehicle where the wheel hubs are attached. Axles are part of the suspension system and are responsible for delivering power to the wheels from the engine via the transmission and differential.

A car’s brakes can be used to stop or slow a vehicle or prevent it from moving when parked or stopped.

Can someone teach me how to find all valid minterms of any given truth table?

Answers

Explanation:

A minterm is a product of variables, in which each variable appears exactly once, either complemented or not. When a truth table is represented in a sum of products form, there is one minterm for each line in the table for which the output is True (1).

Suppose I have a truth table as follows, with inputs A, B and output Z.

  AB Z

  00 1

  01 0

  10 1

  11 0

When I write the minterms, I use a complemented variable where the input is 0, and an uncomplemented variable where the input is 1. The minterm is expressed as a product of those variables.

Here, there are 2 lines in the table with outputs Z=1. The input conditions AB for those outputs are 00 and 10, so the corresponding minterms are A'B' and AB', where the apostrophe indicates the variable is complemented.

This table is then represented by the sum of products ...

  Z = A'B' + AB'

You have all of the valid minterms when you have one for each line of the table where the output is 1.

__

Comment on truth table representation

Truth tables can be represented a number of ways. A nice representation for the purpose of identifying minterms is a list of the output for every possible combination of inputs. We have used that form above.

Sometimes, you may see minterms listed as decimal numbers in the range of 0 to 2^n -1 when there are n input variables. Then, the minterms are developed from the binary equivalents of those decimal numbers.

Example:

Logic with 4 input variables has minterms 7, 8, and 15. The binary equivalents of these numbers are 0111, 1000, 1111. The corresponding minterms (for inputs a, b, c, d) are a'bcd + ab'c'd' + abcd = z. Three numbers are listed, so we know we have all of the valid minterms when we have three corresponding minterms.

__

Additional comment

In some cases, outputs will be listed as "don't care." Another set of minterms can be generated for the don't cares. These can be used in the logic minimization process.

Explanation:

In the early 1900s, aircraft carrier was developed and used that opened the door for naval use of aircraft.

What is aircraft carrier?

A vessel that acts as a seagoing airbase and has a full-length flight deck as well as spaces for storing, preparing for deployment, and bringing back aircraft is known as an aircraft carrier.

Since then, the number of routes has continuously decreased. Throughout the 1990s, it remained at 12 carriers, and after 9/11, it dropped to 11 in 2007.

Congress authorised a minimum force of 11 carriers in 2011 because of concern that the number of aircraft will decline much further. Ten aircraft carriers from the Nimitz class are active in the US Navy.

A battleship that only serves as a seagoing airbase, equipped with a full-length flight deck with areas for deploying and retrieving aircraft, is called an aircraft carrier.

Thus, the answer is aircraft carrier.

The ________________ attraction between the Earth and the moon is ______________ on the side of the Earth that happens to be ____________ the moon, simply because it is ________. This attraction causes the water on this “_________” of Earth to be pulled ___________ the moon.

Answers

Answer:

Gravitational; strongest; facing; closer; near side; toward.

Explanation:

The gravitational attraction between the Earth and the moon is strongest on the side of the Earth that happens to be facing the moon, simply because it is closer. This attraction causes the water on this “near side” of Earth to be pulled toward the moon. These forces of attraction and inertia tends to keep the water in place and consequently, leads to a bulge of water on the near side with respect to the moon.

Also, you should note that what is responsible for the moon being in orbit around the Earth is the gravitational force of attraction between the two planetary bodies (Earth and Moon).
