En una cubeta hay agua que se encuentra a temperatura ambiente (Ta= 20°C). En ella se deposita un yunque de hierro de 25 kg que se encuentra a 320°C. Luego de un breve momento, el pedazo de metal es extraído de la cubeta, donde se le mide, por medio de un termómetro digital la temperatura nuevamente, resultado marcar 60°C. Considerando que el calor especifico del hierro es de 448 [J/Kg°C] Determine: a) Que material absorbe calor (1p) R/:
b) Que material cede calor (1p)
c) Temperatura de equilibrio térmico (2p)
d) Método de transferencia que predomina (2p)
e) Cantidad de energía que está fluyendo [Q] (6p: 2p identificar, 2p relacionar y 2p resolver

Did the proton move into a region of higher potential or lower potential? did the proton move into a region of higher potential or lower potential? because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of higher potential to a region of lower potential.because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of lower potential to a region of higher potential.because the proton is a positive charge and it slows down as it travels, it must be moving from a region of higher potential to a region of lower potential.because the proton is a positive charge and it slows down as it travels, it must be moving from a region of lower potential to a region of higher potential.request answerpart bwhat was the potential difference that stopped the proton? express your answer with the appropriate units.î”v î” v = nothingnothingrequest answerpart cwhat was the initial kinetic energy of the proton, in electron volts? express your answer in electron volts.ki k i = nothing ev request answerprovide feedback

Aman throws a football straight into the air. as it rises, it slows down. which type of energy is the football gaining?

The star betelgeuse is about 600 light-years away. if it explodes tonight, a. we'll know because debris from the explosion will rain down on us from space.b. we'll know it immediately because it will be brighter than the full moon in the sky.c. we won't know about it until 600 years from now.d. none of the above.
