A(n)<u> Solid</u> coupling is used when it is necessary to extend the length of a shaft or to provide a means of disconnecting a shaft.
The basic function of all couplings is to transmit power, accommodate misalignment and compensate for axial movement (end movement of shafts). Sometimes, a coupling is asked to absorb shock or vibration. A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power.
Types of Couplings:
- Rigid coupling.
- Flexible coupling.
- Sleeve or muff coupling.
- Split muff coupling.
- Flange coupling.
- Gear coupling.
- Universal joint (Hooke's joint)

Answer:
Parasympathetic nervous system
Explanation:
The autonomic nervous system has 3 divisions. One of them is the parasympathetic nervous system. The function of this system is to conserve energy by slowing down the heart rate, it also increases intestinal and gland activity and relaxes sphincter muscles. parasympathetic system conserves energy as it slows the heart rate, increases intestinal and gland activity, and relaxes sphincter muscles in the gastrointestinal tract.
While the sympathetic system prepares the body for high-energy activity, the parasympathetic nervous system relaxes the body and inhibits many high energy functions.
In this example, Paul was awakened frightened but he realized it was only the cat. The subdivision of the nervous system that helped him calm down and restore his function's back to normal would've been the parasympathetic system since it's the one in charge of relaxing the body.
Consequence
B can be considered a reinforcer if Behavior A brings about a desirable
Consequence B, and Behavior A reoccurs. A reinforcer is a consequence that will
increase a behavior, while a punisher is a consequence that may decrease a
behavior.
Discrimination is treating people unequally because of prejudice or partiality. Martin Luther King, Jr., gave his "I Have a Dream" speech at the Lincoln Memorial. President Lyndon Johnson signed the Civil Rights Act of 1964 into law. An ethnic group is a group of people that share a common ancestry, nationality, or culture.
