AlekseyPX

Answer:

The next step is prototype testing

Explanation:

The stages of the design process are;

1) Situation analysis

Paper based research is conducted on the situation to obtain the situation parameters

2) Brief writing

With the situation analysis developed above, the brief of the current situation is put down on paper

3) Problem research

The problem is researched and experimented on with the development of a paper based proof of the possible concept

4) Specification writing

The specifications of the problem are outlined

5) List the possible solutions

The possible solutions are brainstormed and listed

6) Preferred solution selection

The preferred solution is selected based on the constraints in the situation

7) Create working drawing/plan

The working design drawing of the selected solution or concept is completed and evaluated for applicability

8) Building of a prototype

The design is converted into a prototype which is a model of the actual solution

9) Testing of the prototype

The prototype is tested for functionality, for ability to work in the intended situation and/or in the intended system

10) Report writing

A report is made on the outcome of the tests for review before production

Therefore, after the prototype is created, stage 8, the next step is the testing of the prototype stage 9.

Determine the mass of an object that has a volume of 88.6 ml and a density of 9.77 g/ml.
Nostrana [21]
Given:
The volume is V = 88 mL
Density, d = 9.77 g/mL

Because mass = volume *  density, therefore the mass of the object is
m = (88.6 \, mL)*(9.77 \,  \frac{g}{mL} )=865.62 \, g

Answer: The mass is 865.2 g  or  0.865 kg

A sample of ethanol (C2H6O) has a mass of 0.2301 g. Complete combustion of this sample causes the temperature of a bomb calorime
Keith_Richards [23]

Answer:  4.994\times 10^{-3}  moles

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to molecular mass , occupies 22.4 L at STP and contains avogadro's number 6.023\times 10^{23} of particles.

To calculate the moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}

Given mass of ethanol = 0.2301

Molar mass of ethanol = 46.07 g/mol

\text{Number of moles of ethanol}=\frac{0.2301g}{46.07g/mol}=4.994\times 10^{-3}

Thus there are 4.994\times 10^{-3}  moles of ethanol are present in the sample.

Elza [17]

Answer:

The Cape Horn was one of the most important routes for maritime trade, leading to sailing vessels.

the difficulty of all this is that it presents great iceberg and climatic factors that do not help the boats. nowadays other commercial routes were created that made this channel only be transited by larger ships, or oil tankers.

Explanation:

Sailing in its waters is still considered one of the greatest nautical challenges, so there are various sporting and tourist events that use this route, some as part of the circumnavigation of the globe, among which are important yacht regattas, such as the Vendée Globe.
