Normal body temperature for healthy babies is in the range of 96.8Â°F to 98.6Â°F, or 36Â°C to 37Â°C. If the baby's body temperature rises above 100.4Â°F to 101.3Â°F, then it is considered as indication of fever. If it falls below 96.8Â°F then the child has low temperature and needs immediate warming up.
Tornadoes usually lasts only a few minutes, but they are very intense. Their wind speeds range from 18 to 140 m/s. The damage path of a tornado is usually less than 500 meters wide and it travels at less than 16 m/s. Each year, the United States ranks number one in tornado incidence with Australia coming in second. Very often, the most devastating ones occur in Bangladesh.
A tornado is a column of strongly rotating winds that may be shaped like a funnel or a pillar. The column reaches down from a cloud to touch the ground. It then moves along the ground at about 28 miles (45 kilometers) an hour, but the speed of a tornadoâs winds may be 300 miles (500 kilometers) an hour.
