Explain : I've got a lot of help from this website :D
Answer:
All machines have three fundamental hazards: moving parts, point of operation, and the power transmission.
Explanation:
The unit that supplies power to the machine is a critical hazard due to high energy sources being potential fatal if proper protocols are not followed. This is why lockout tagout (LOTO) measures are put in place in order to protect people while they work on equipment.
Answer:

Explanation:
The mass inside the rigid tank before the high pressure stream enters is:



The final mass inside the rigid tank is:



The supplied air mass is:



Diode logic gates are not suitable for cascading operation because the pull-down or pull-up resistance within makes them a high output resistance device.
<h3>What is a
cascading operation?</h3>
A cascading operation can be defined as a process which involves the use of a circuit breaker's current-limiting capacity in order to enable an installation of lower-rated and lower-cost circuit breakers.
According to the National Electrical Code (NEC), diode logic gates are not suitable for cascading operation because the pull-down or pull-up resistance within makes them a high output resistance device.
