Practicing Self-Care. 1  1. Take care of yourself. There are many small steps to this one action. 2  2. Put care into your appearance. You don't have to look like Brad Pitt to start building your self confidence. 3  3. Exercise regularly. Part of taking care of yourself is getting exercise.  4. Sleep well.
Stationary Waves. Stationary or standing waves are formed in a medium when two waves having equal amplitude and frequency moving in opposite directions along the same line, interfere in a confined space. Generally, such waves are formed by the superposition of a forward wave and the reflected wave. Both longitudinal and transverse types of waves can form a stationary wave. When reflection occurs at a free end, there is no reversal of phase. i.e., a crest returns as a crest and a trough as a trough.
A stationary front forms when a cold front or warm front stops moving. This happens when two masses of air are pushing against each other but neither is powerful enough to move the other. Winds blowing parallel to the front instead of perpendicular can help it stay in place. A stationary front may stay put for days. If the wind direction changes the front will start moving again, becoming either a cold or warm front. Or the front may break apart. Because a stationary front marks the boundary between two air masses, there are often differences in air temperature and wind on opposite sides of it. The weather is often cloudy along a stationary front and rain or snow often falls, especially if the front is in an area of low atmospheric pressure. On a weather map, a stationary front is shown as alternating red semicircles and blue triangles like in the map at the left.
