2 Answers 2. The gate-source threshold voltage is the voltage that is required to conduct (usually) 100 uA of current into the drain. Different MOSFETs have different definitions and some devices define the threshold voltage at up to 1 mA drain current.
The Earthâs Centre is 1000 Degrees Hotter than Previously Thought. Scientists have determined the temperature near the Earthâs centre to be 6000 degrees Celsius, 1000 degrees hotter than in a previous experiment run 20 years ago.he layers of the Earth and their temperatures: crust, upper and lower mantle, outer core and solid iron core. Credit ESRF. The Earthâs core consists mainly of a sphere of liquid iron at temperatures above 4000 degrees and pressures of more than 1.3 million atmospheres.
Temperature Extremes. Earth's surface temperature depends on how much energy it receives from the sun. The equator, which is in direct sunlight all year, tends to be the hottest place, but the highest air temperature ever recorded was at Death Valley, California, in 1913.It was 56.7 degrees Celsius (134 degree Fahrenheit).ts average surface temperature is following a warming trend. In 2013, Earth's average temperature was 14.6 degrees Celsius (58.3 degrees Fahrenheit), according to NASA.
