Pressure. Do a Google search on the relation between volcanoes and pressure, or even your question.
That's not actually a question, it's a statement. You don't need to beat around the bush; just ask the question.
The classical Physcis said that waves and particles are two different components. In Quantum Physics , we know that light ( or eletromagnetic waves ) demonstrates wave-particle duality. In this case, the light behaves as a collection of particles called photons. The energy of each photon is given by hv.
I'AM 13 YEARS OLD AND MY IQ IS 150 AND IT MEANS I AM GENIUS....AND ITS MAYBE TRUE BECAUSE AT THIS AGE I HAVE STUDIED ABOUT QUANTUM FEILDS THERMODYNAMICS AND PHYSCIS EQUAL TO A GRADUATE SO ITS GOOD
An (inconvenient) unit for force.>Harking back to james watt, an experiment to define a unit for power(today thats the watt)Using a strong horse he timed how long it took to lift a weight up a mineshaftusing a horse and a pulley wheel.His definition for work done was: force (to overcome load) * distance (travelled)His definition for power was work done / time takenExample data:It took 1 minute to lift 165 pounds 200 feet up the shaftSo >force * distance / time = 33000 (lbs force - feet) / minuteIn SI units that is:733.956 newtons - 60.96 metres in 60 seconds= 745.699 Watts ( 1 imperial horsepower)
