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?
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
[tex]Net\ charge(Q_{net})=Q_1+Q_2=2C+(-2C)=0[/tex]
Hence the net charge on the said dielectric is 0

. What is wrought iron? Discuss in brief its chemical composition, properties and applications.
Answer:
Wrought iron is an iron alloy with very low carbon content with respect to cast iron.
Explanation:
It is soft, ductile, magnetic, and has high elasticity and tensile strength. It can be heated and reheated and worked into various shapes.
Answer:
Wrought iron is an ferrous metal with a very low amount of carbon (less than 0.08%) compared to cast iron (2% or more). It is a semi-molten mass of iron with a fibrous sheath (up to 2% by weight), giving it a "grain" similar to wood grain, visible when bent or bent to the point of fracture. Wrought iron, malleable, easy to draw, corrosion resistant and easy to weld. Explanation:

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 ?
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 bandwidthBandwidth = 2[tex]F_{s}[/tex]

O C. Horsepower; torque; horsepower
O D. Horsepower; torque; torque
Clear my choice
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.

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.
Answer:
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
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?
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.

Find the distance of the line 3x + 4y + 5 = 0 from the point (2,-3).
Explanation:
The point on the line 3x + 4y = 5, which is equidistant from (1, 2) and (3, 4) is. Therefore, the point is (15, -10).
In the figure, particle 1 of mass m1 = 3.1 kg slides rightward along an x axis on a frictionless floor with a speed of 5.0 m/s. When it reaches x = 0, it undergoes a one-dimensional elastic collision with stationary particle 2 of mass m2 = 4.6 kg. When particle 2 then reaches a wall at xw = 79 cm, it bounces from the wall with no loss of speed. At what position on the x-axis does particle 2 then collide with particle 1?
Answer:
We use Eq 9−67 and 9−68 to find the velocities of the particles after their first collision (at x=0 and t=0 )
