the resistance, Ro of a platinum varies with temperature theta °C as measured by a constant-volume gas thermometer according to the equation R theta= Ro(1+ 800 a theta - a theta²) The resistance ,Ro of platinum varies with temperature theta°C as measured by a constant volume gas thermometer according to the equation Rtheta=Ro(1+800atheta-atheta²) where a is a constant. Calculate the temperature on the platinum scale corresponding to 400°C on the gas scale?

from 1609, galileo galilei used the recently invented telescope to observe the sun, moon and planets. he saw the mountains and craters of the moon, and for the first time revealed the planets to be worlds in their own right. galileo also provided strong observational evidence that planets orbited the sun.

his discoveries about the moon, jupiter's moons, venus, and sunspots supported the idea that the sun - not the earth - was the center of the universe, as was commonly believed at the time.galileo turned his gaze toward venus, the brightest celestial object in the sky - other than the sun and the moon.

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !
