Answer:

  A.  15 cm²

  B.  15 cm²

Explanation:

A. Original Formula

The diagram shows the values of a, b, h. Put these in the original formula to find the area.

  A = 0.5(a+b)h

  A = 0.5(3 +7 cm)(3 cm) = 0.5(10 cm)(3 cm) = 15 cm²

__

B. Splitting Method

The base of each triangle is half the difference between the two base lengths.

  triangle base = (7 -3)/2 = 2 . . . cm

The area of a triangle is given by the formula ...

  A = 0.5bh

  A = 0.5(2 cm)(3 cm) = 3 cm²

The area of the central rectangle is given by ...

  A = bh

  A = (3 cm)(3 cm) = 9 cm²

Then the area of the trapezium is ...

  A(triangle) +A(triangle) +A(rectangle) = A(trapezium)

  (3 cm²) +(3 cm²) +(9 cm²) = A(trapezium) = 15 cm²

Engineer It A water heater is a tank in which cold water is heated. Cold water flows into the tank to keep it full. A heating element warms the water inside the tank. The heated water can then be sent to hot water faucets in a building. Assume that a water heater design requires the hottest water possible to be sent to hot water faucets in a building. Where would be the best place for the hot water outlet pipe to be attached to the tank: the top, the middle, or the bottom of the tank? Explain your answer.

Explanation:

I think it would be the top, the hotter the water the more pressure and sense pressure builds at the top of water heater tanks you would want the outlet pipe at the top.

What is Heater?

The process of transforming electrical current into heat energy is known as electric heating. An electrical resistor serves as the heating element in an electric heater, and heat is generated there when an electric current flows through it.

This procedure is frequently utilized in a wide range of domestic applications. from using an electric burner to prepare food, a kettle to boil water, and of course, house heating.

With one significant exception—they don't rely on a boiler and a system of pipes to produce the heat—electric heaters and radiators function exactly like your central heating radiators that are plumbed in.

Therefore, I think it would be the top, the hotter the water the more pressure and sense pressure builds at the top of water heater tanks you would want the outlet pipe at the top.

Which of the following is a Dashboard Scoreboard for alignment of the business where information is constantly flowing through the Tiers so immediate actions can be taken?

Answers

Answer:

What is a dashboard?

A dashboard is an information management tool used to track KPIs, metrics, and key data points that are relevant to your business, department, or a specific process. Dashboards aggregate and visualize data from multiple sources, such as databases, locally hosted files, and web services. Dashboards allow you to monitor your business performance by displaying historical trends, actionable data, and real-time information.

Dashboards actually take their name from automobile dashboards and they are used in much the same way. For the sake of an analogy, let’s look at a car. There may be hundreds of processes that impact the performance of your vehicle if you look under the hood. Your car’s dashboard summarizes this using visualizations so you can focus on what matters most: safely driving your vehicle.

For businesses, there are hundreds of processes that impact your performance if you look ‘under the hood’, so to speak. And with a wealth of data made available these days, managing and extracting value from it can be difficult. Simplifying data analysis and distribution through tools like dashboards is a way to help businesses rev their engines and make smarter, better, faster data-driven decisions.

And a well designed dashboard levels up your approach to information management. Everyone in the business, regardless of role, has questions about your company performance, whether it be campaign performance, new wins, or churn rate. Dashboards bring everyone (and your metrics) together in one place to answer these questions.

Answer:

C

Explanation:

As horsepower is the rate  at which that force torque  is a twisting or turning force, horsepower is produced. Hence option  C is correct.

What is horsepower?

Horsepower is defined as a unit used to describe the pace at which labor is done or to quantify power, frequently in relation to the output of engines or motors. Standardization and types of horsepower vary widely. A car's engine power is measured in horsepower (hp); the greater the number, the more power is transferred to the wheels and, in theory, the faster it will travel.

To put it simply, horsepower is your overall speed and power, whereas torque allows you to feel the sensation of acceleration when you put your foot down. When you realize that horsepower is derived from torque, this makes sense. Torque is a unit of rotational or twisting force. The power an engine produces is referred to as horsepower.

Thus, as horsepower is the rate  at which that force torque  is a twisting or turning force, horsepower is produced. Hence option  C is correct.

Assume that you have a wireless application you would like to design,build and sell as a commercial product.You have selected a target frequency in the UHF range.How would you decide what frequency to use and how would you get permission to use it ?

Answers

The frequency to use depends on the range and distance of signal transmission. There is government communication agency in charge of issuing license in order to get carrier frequency in which the application can work with.

UHF means Ultra - high frequencies which is mostly used in television broadcasting and mobile phone. Frequency range of the UHF is between 300MHz to 3GHz.

Assuming that you have a wireless application you would like to design, build and sell as a commercial product. And you have selected a target frequency in the UHF range.

Most wireless applications make use of radio wave and microwave depending on the range of distance in which the signal will travel.

The first thing to do is to determine the distance. Whether is short or long distance.Then get a license from the right  government communication agency so that a carrier wave frequency will be allocated for you.  Determine the side bands frequencies and Calculate the bandwidth

Bandwidth = 2[tex]F_{s}[/tex]

Where [tex]F_{s}[/tex] = sidebands frequency

Purchase all the necessary devices and gadgets like transmitter, oscillator, antenna e.t.c

Answers

Damien can study how the material behaves when immersed by using a; Stress - Strain Curve

To determine the elasticity of a material, we need to find the elastic modulus because the elastic modulus is what quantifies the elasticity of the material.

Now, formula for elastic modulus is;

E = stress/strain

Now, to study the effect on a material's elasticity after it is submerged in water for varying durations, since elasticity is based on the stress and strain on the material, we need to draw a graph of stress vs strain which is also called a stress - strain curve.

The stress strain curve is a graphical tool that helps us know to know the amount of load a material can take before it will stretch and break.

A positively charged electric has a charge of 2 Coulombs. If 12.5x10^18 free electrons are added to it, what will be the net charge on the said dielectric?

Answers

The net charge on the said dielectric is 0

1C = 6.25 * 10¹⁸ electrons; hence:

-12.5x10¹⁸ free electrons = (-12.5x10¹⁸ free electrons * (1C/ 6.25 * 10¹⁸ electrons))

-12.5x10¹⁸ free electrons = -2 C

A positively charged electric has a charge of 2 Coulombs, hence:

Q₁ = 2C

12.5x10¹⁸ free electrons are added to it, hence:

Q₂ = -2C
