nasty-shy [4]2 years ago
6 0

Answer:Report writing consists of the history and facts of a project or of any kind of event. It is useful to record past history and an overall summary of decisions. Report writing helps to solve problems as a path. Writing a report will guide you in a way that will modernize details of the improvements and upcoming plans.

There is evidence that liquid water existed on Mars at some time in the past. What is the evidence found indicating the presence
Norma-Jean [14]
There mag be water on Mars but it’s not very easy to spot, but that is besides the point,

Mars is a smaller planet then Earth, thus it has less gravity, meaning when water evaporates into the atmosphere of the planet the water slowly escapes into space, so there is less and less water on the planet.

Hope this helps!

A cylindrical resistor element on a circuit board dissipates 0.6 W of power. The resistor is 1.5 cm long, and has a diameter of
Burka [1]

Answer:

a. 51.84Kj

b. 2808.99 W/m^2

c. 11.75%

Explanation:

Amount of heat this resistor dissipates during a 24-hour period

= amount of power dissipated * time

= 0.6 * 24 = 14.4 Watt hour

(Note 3.6Watt hour = 1Kj )

=14.4*3.6 = 51.84Kj

Heat flux = amount of power dissipated/ surface area

surface area = area of the two circular end  + area of the curve surface

=2*\frac{\pi D^{2} }{4} + \pi DL\\=2*\frac{\pi *(\frac{0.4}{100} )^{2} }{4} + \pi *\frac{0.4}{100} *\frac{1.5}{100}

= 2.136 *10^-4 m^{2}

Heat flux =\frac{0.6}{2.136 * 10^{-4} } = 2808.99 W/m^{2}

fraction of heat dissipated from the top and bottom surface

=\frac{\frac{2*\pi D^{2} }{4} }{\frac{2*\pi D^{2}}{4} + \pi DL } \\\\=\\\frac{\frac{2*\pi *(\frac{0.4}{100} )^{2} }{4} }{\frac{2*\pi *(\frac{0.4}{100}  )^{2} }{4} +\pi *\frac{0.4}{100} *\frac{1.5}{100} } \\\\=\frac{2.51*10^{-5} }{2.136*10^{-4} } \\\\\= 0.1175

=11.75%

Pam Jones worked for 41 years at the same company and had positive performance ratings and personnel records. She needed a calcu
UNO [17]

Answer:

a) The key issues are the sue for libel and the evidence.

b) I would make a deal with her and implement a security program in the company.

Explanation:

The main issue in this case is that Pam Jones sued the company for libel, and the company remains in a position in which it has to prove that the internal investigation followed the right steps and indeed, the proves reflected that she was guilty and the fact that she got fired was correct.

The important here is exactly that the theft can be proved.

As an HR Director, I would give the correct proves in order to win the case, and if that is impossible, because of the tools and evidence, I would make a deal with her where both parts can be adequate to the problem.

She can´t be working again in the company but she can get financed according to her working years; also I would use this case as a growing opportunity by implementing new security methods that give more confidence between the company and its employees.

An important concept to aid understanding of electromagnetics is electrical length. Electrical _________ is a unitless measure t
kondor19780726 [428]

Answer: Electrical length is a unitless measure that refers to the length of a wire or device at a certain frquency. It is defined as the ratio of the physical length of the device to the wavelength of the signal frequency.

Explanation:

In nature, the maximum speed achievable for any interaction or perturbation along a medium (like a wire) can't be higher than the speed of light, otherwise it would be violating Einstein's Relativity Theory.

So, in a given circuit, the voltage and current aren't set up instantaneously, and a finite time exists since a battery is connected to a circuit till a stable current  traverses a load resistor connected to it.

Now, the electrical length, defines how important in is this delay, in the calculation of the voltage through the resistor, for instance.

We can write the electrical length (L.E.) as follows:

L.E. = L / (v/f) = L / λ

As we can see, the effect depends not only on the circuit dimensions, but the frequency of the signal as well.

If L.E. is much smaller than λ, this means that we can neglect the effects of the delay, and we can use the circuit theory, namely KVL, KCL and Ohm's law to analyze the circuit, assuming that the current establishes instantaneously.

Otherwise, the current and voltage concepts are not valid anymore, as we need to think in terms of propagation of electromagnetic waves, like in transmission lines and antennas.

Roughly, if L.E. ≤ 20 λ, we say that we are still in the realm of the circuit theory.
