An isometric contraction is the kind of contraction that leads to development of tension but no increase in length.
An isometric contraction occurs as the muscle produces tension without changing the angle of a skeletal joint. Isometric contraction is a static muscle action that helps to maintain the posture. For example, the antigravity muscles. It occurs in the biceps when the arms may be holding a weight. In such a posture, the biceps enlarge due to holding of weight and produces tension but do no increase in length. It stops the flexion of elbow. In such contraction, no work is done, and lesser amount of heat energy is released in comparison to isotonic contractions.

The answer to the question about why would nationalism lead to intolerance and persecution of other ethnic or national groups is explained below.
Explanation:
When a nation promotes its own interests, over the interests of other nations, it is called as nationalism. Nationalism creates a feeling of inferiority within the minorities of a country, which may lead to intolerance among them.
Countries usually contain diverse group of people, who are from different backgrounds, ethnicity, etc. Large group of people in a country or region creates pride among them of their sharing of common heritage, history, backgrounds, ethnicity, etc. This thing may leave many minorities alone and make them feel inferior in the same region or country, which would no doubt lead to intolerance among them.
