When designing an engineering solution, certain criteria and constraints must be considered. Criteria are the features of the de
kondor19780726 [428]

Answer:

The criteria listed in order of importance are;

1) To be inflated in the event of a collision in order to protect the occupants of the front of the vehicle

2) To be able to withstand the load of the breaking force of the occupants in the front seat of the vehicle during a collision

3) To be relatively tough so as to resist being torn on impact with a sharp object

The constraints listed in order of importance are;

1) How is the model design able to sense a collision that requires the airbag to be inflated

2) The uncertainty of the load the airbag will withstand upon collision

3) The possible hazard that could be caused by the gas used to inflate the airbag

4) The usage/interaction tendency between the vehicle occupant and the airbag system

Explanation:

In order to produce an effective design, it is important to be able to foresee the possible deficiencies of an idea so as to be able to mitigate the problems before an actual incident happens.

What mass of natural gas (ch4) must you burn to emit 272 kj of heat?
balandron [24]
CH4 + 2 O2 ---> CO2 + 2 H2O Q = 891,6 kJ / mol CH4

1 mol CH4 = 16 g

16 g ---- 891,6 kJ
x g ----- 272 kJ

x = 272 kJ × 16 g / 891,6 kJ = 4,88 g

You must burn 4,88 g of CH4.
