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

Learning goal: to understand newton's 1st law. newton's principia states this first law of motion: an object subject to no net force maintains its state of motion, either at rest or at constant speed in a right line. this law may be restated as follows: if the sum of all forces acting on an object is zero, then the acceleration of that object is zero. mathematically this is just a special case of the 2nd law of motion, f⃗ =ma⃗ , when f⃗ =0. when studying newtonian mechanics, it is best to remember the 1st law in two ways: if the net force (i. e., sum of all forces) acting on an object is zero, the object will keep moving with constant velocity (which may be zero). if an object is moving with constant velocity, that is, with zero acceleration, then the net force acting on that object must be zero. complete the following sentences to see if you can apply these ideas. part a if a car is moving to the left with constant velocity, one can conclude that
