¿En que consideras que se diferencian los movimientos de vibracion de dos sólidos a diferente temperatura? ¿Como es el movimientode una particula con energía cinética igual a cero?

Tomando en cuenta la relación que existe entre energía cinética y temperatura ¿podría enfriarse más una sustancia cuyas particulas no poseen energía cinética? ¿Acaso existe una temperatura mínima?​

What is a costume plot? why is it important to a film or theater production?

Beryl states that insulation with the smallest possible thermal conductivity is best to keep a house warm in winter, but worst for keeping a house cool in summer. sapphire insists the reverse is true: low thermal conductivity is good in the summer, but bad in the winter. which one, if either is correct? a. beryl, because low thermal conductivity results in low heat transfer. b. beryl, because low thermal conductivity results in high heat transfer. d. sapphire, because low thermal conductivity results in high heat transfer. e. neither, because low heat transfer is desirable both in summer and in winter.

Asmall 12.00g plastic ball is suspended by a string in a uniform, horizontal electric field with a magnitude of 10^3 n/c. if the ball is in equilibrium when the string makes a 30 ° angle with the vertical, what is the net charge on the ball?
