Answer:
It has poor tensile strength despite having high compressive strength
Explanation:
Concrete exhibits high compressive strength when used. However, it has very low compressive strength. This is the reason why concrete is normally combined with steel to make a composite building material called reinforced concrete. The steel reinforces concrete hence increasing the tensile strength in RC buildings. The end composite is durable and fireproof. Generally, the main reason why concrete is not use on its own is due to its poor tensile strength.
Answer:
add resistance to a circuit
Explanation:
It depends on the design in which it is incorporated. A fixed resistor has many uses, including, but not limited to ...
- dropping voltage
- limiting current
- contributing to a time delay
- adjusting frequency response
- eliminating (or creating) signal reflections
- acting as a fuse
- calibrating or trimming a response
- providing protection against electrical shock or ESD
- acting as a reference when measuring variable resistors
Answer: Eye injury
Explanation: small material such as dust, dirt, and metal shards can harm your eyes with potential blindness or infection.
Answer:
And Im still going with B..
Answer:
The industrial systems of the future are seen as complex systems, composed of vast numbers of devices, interacting with each other and with enterprise systems continuously.
summary:
they are related because they ARE a system. well, a type.
hope this helps!! :)
