Answers

Answer 1
Answer:

Answer:

  • Option-(B):Neither Technician A nor Technician B is correct, As the whole process does not follow the Otto cycle.

Explanation:

Engine Operation:

The engine operation occurs in four main stages, as its function of any four-stroke engine requires the crankshaft to rotate twice in the machine covering about 720° degree of rotation while on its position.

While, the four main stages for the engine to operate are as follow:

  1. Intake:The fuel is injected inside the piston.
  2. Compression:As during the compression the volume is decreased and as more energy is released due to this phase of the engine.
  3. Power: During the power stage the expansion of the gases which are compressed before are expanded, providing a power stroke to the engine.
  4. Exhaust: The phase during the engine cycle in which the air is exhausted out from the combustion chamber of the engine.

Answer 2
Answer:

C. Only Technician B is correct.

What does it mean to be a socially responsible consumer? Use an example to support yourexplanation.

Answers

A socially responsible consumer is a consumer who cares about the social impact that the products he buys have on the world around him. Socially responsible consumers avoid products that they think harm society. Instead, they buy goods and services from companies that they believe do a better job of taking care of the world.

An example of such a behaviour would be a person who shops in small stores as opposed to shopping in supermarkets, because he believes that it is important to support local businesses. Another example is that of someone who buys free trade coffee, in order to ensure that his purchase does not have a negative impact on coffee farmers around the world.
