Correct answer is option E. No dimensions

As we know formula Pressure (P) is \frac{F}{A}

also,

  • Dimensional formula of <em>Pressure is </em>M^{1}L^{-1}T^{-2}
  • Dimensional formula of <em>length is L </em>
  • Dimensional formula of <em>mass is M</em>
  • Dimensional formula  of <em>velocity is </em>L^{1} T^{-1}

So, as given W=\frac{P*L^{3} }{M*V^{2} }

Dimensional formula of W =\frac{M^{1}L^{-1}T^{-2}  L^{3}  }{M^{1} L^{2}T^{-2}   }

since all terms get cancelled

Work is dimensionless i.e no dimensions

Describe at least one way you take advantage or could take advantage of each of the different forms of energy
Scorpion4ik [409]

Answer:

Kinetic energy can be used to develop electric energy which can be used as electricity.

Explanation:

The kinetic energy can be harnessed; much like some hydro power technologies harness water movement. A way to convert this kinetic energy into electric energy is through piezoelectric. By applying a mechanical stress to a piezoelectric crystal or material an electric current will be created and can be harvested.

Kinetic energy is also generated by the human body when it is in motion. Studies have also been done using kinetic energy and then converting it to other types of energy, which is then used to power everything from flashlights to radios and more.

I wish to have a computer whose machine-level instructions are all 32 bits each. If I want to have all instructions of the form
melisa1 [442]

Answer:

Maximum number that can be represented by 13 bits  is 8192 Instructions

Explanation:

number of instructions = 1000

number of bits = log(1000) x number of register

                          = 6 bits

Since the complete instruction must have 32 bits, then

remaining number of bits = 32 - 6 = 236

number of registers in instruction = 2

number of bits per register = 26/2 = 13

Maximum number that can be represented by 13 bits = 2^{n}

                       = 2¹³ = 8192

In the case, the software engineers present at the meeting would concern themselves with ________-level strategy
jekas [21]

The level of strategy which the software engineers would concern themselves with would be highly dependent on the nature of the case or situation.

<h3>What is a strategy?</h3>

A strategy can be defined as a set of guiding principles, procedures, actions, and decisions that a business organization or an individual combines, in order to achieve its aim, objectives and goals.

Basically, developing a strategy is essential because it helps to attract new customers and gives a competitive advantage over rivals in the industry.

<h3>The types of strategy.</h3>

In Software engineering, there are different types of strategy used by software engineers and these include:

  • Tactical strategy
  • Product management strategy
  • Lifecycle process strategy
  • Technology strategy
  • Support strategy
  • Customer strategy

Furthermore, there are three (3) main <u>levels</u> of strategy in software engineering and these are:

  1. Business-level strategy
  2. Functional-level strategy
  3. Corporate-level strategy

In this scenario, the level of strategy which the software engineers present at the meeting would concern themselves with would be highly dependent on the nature of the case or situation.
