(a) How long can you rapidly climb stairs (116/min) on the 93.0 kcal of energy in a 10.0-g pat of butter? (b) How many flights is this if each flight has 16 stairs?
GEOL 204 Environmental geology Energy Balances What goes in and what goes out Input = Output Energy input (earth) = energy output (earth) Radiation: provides energy to the earth Electromagnetic waves Wavelength = Frequency = Speed = 3x10^8 m/s Wavelength * Frequency = speed Frequency = Speed / wavelength Photons (Duality) / (Light) Particle Pulse h = Plank Constant = 6.63*10^-34 j/s Energy (E) = h * frequency High Energy Will cause chemical reaction Low Energy Will cause more vibration Flux (F) or (S) – Energy per area per time Area: Watt/cm Time: /s Perpendicular to the surface to calculate Flex 1370 Watts/ m^2 = earth rec
