The larger these peaks and valleys are, the harder it is to slide the object. You can learn more about friction in How Brakes Work. A clutch works because of friction between a clutch plate and a flywheel. We'll look at how these parts work together in the next section.
You should take children older than 3 months to the emergency room (ER) for a fever if the fever is more than 104 degrees for a long period of time. Ice them down first and then bring them to the ER.
1 In newborns (younger than 28 days), any body temperature above 38.3 degrees Celsius/101 degrees Farenheit should be treated as a medical emergency. 2  Even up to the age of 3 months, any body temperature above 38 degrees Celsius should be monitored very closely and if possible, immediate medical attention should be sought. A core body temperature (rectal) above 38 degrees Celsius/100.4 degrees Farenheit is considered as a fever in a child. 2  In most cases this is just considered as a mild fever and may be managed in the home environment until medical attention can be sought by the next day.
