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.
The wind caused by a tornado is its primary source of damage and destruction. Tornadoes are measured based on the Enhanced Fujita Scale. The weakest tornadoes, with wind speeds 65 to 85 mph, can rip branches off trees, uproot small trees and tear shingles off of houses. An EF 1 tornado has wind speeds ranging from 86 to 110 mph. These winds can tear up mobile homes and rooftops and cause exterior damage to houses. An EF 2 tornado's winds range from 111 to 135 mph. Winds of this consistency uproot mobile homes, tear roofs completely off houses and cause foundation damage to homes. A tornado with winds in the 136 to 165 range is classified as an EF3 tornado.
