Answer:
Since the hockey puck is moving at constant velocity
So here we will have
where we have
a = acceleration of the object
m = mass of object
so here since we know that acceleration is defined as rate of change in velocity
so here we will say that
so we have
so we will say that hockey puck is in equilibrium as there is no net force of it
Answer:
Cp = 0.142 [cal/g*°C].
Explanation:
In order to solve this problem, we must use the following equation of thermal energy.
where:
Q = heat energy = 60 [cal]
Cp = specific heat [cal/g*°C]
T_final = final temperature = 10[°C]
T_initial = initial temperature =40[°C]
m = mass of the substance = 14 [g]
Now replacing:
Answer:
La ecuación que expresa la conservación de energía es: KEi + PEi = KEf + PEf. Si conoce la energía potencial solo para algunas de las fuerzas, entonces se debe utilizar la ley de conservación de la energía en su forma más general: KEi + PEi + Wnc + OEi = KEf + PEf + OEf, donde OE significa todas las demás energías.
Answer:
