Well, honey, it's simple. Just engage those muscles like you're trying to impress a date. Tensing them properly helps support your joints and stabilizes your body, reducing the risk of injury. So, don't half-ass it - give those muscles the attention they deserve and keep yourself safe while breaking a sweat.
Ear rumbling is a voluntary control of the tensor tympani muscle in the ear, which can create a low-frequency rumbling sound. This muscle can be activated by focusing or tensing certain muscles in the head and neck, causing the eardrum to vibrate.
Abdominal guarding is a natural response of the abdominal muscles to protect the internal organs from pain or injury. It is characterized by a tensing or tightening of the abdominal muscles, usually in response to palpation or movement that causes discomfort or pain in the abdomen. It can be a sign of underlying issues such as peritonitis, inflammation, or infection in the abdominal cavity.
Reverse kegels are almost the opposite of normal kegels. The idea is to learn to relax the pelvic floor instead of tensing them. So reverse kegels involve isolating the same mucle group and slightly pushing them downwards. Some say it's almost like trying to make yourself go to the toilet faster than usual. You can find detailed instructions on doing them at the related link.

If you have time, tensing your muscles helps.

Vomiting tends to make the body tense up. The hand muscles might contract as a result of this tensing. Also, vomiting can cause dehydration which can make muscles contract.
When muscles are tensed, they can increase blood pressure. Fighter pilots take advantage of this by tensing their gut muscles to avoid blacking out at high-G conditions.
No. Muscle tone is the tension between antagonistic muscle groups. The way to increase it is to strengthen both muscle groups. Just tensing stomach muscles will not make them stronger-anymore than curling a pencil will make your biceps stronger. To get stronger, you must work, in other words, move a certain weight a certain distance in a certain time. That is resistance training-and simply tensing muscles is not using resistance to strengthen them.
Relax. Muscles can only work by contracting (tensing). When an opposite force is desired, an opposite muscle contracts.
Possibly. Our bodies don't like to be cold and muscles may react by tensing up when exposed to draught.
I think it is just a spasmodic movement, the nerves tensing and muscles rippling.
A little. The trick is to relax the muscles when you are getting it as tensing up makes it painful.
