En el arreglo mostrado el radio de la polea es R, su momento de inercia alrededor del eje de rotación es I y el resorte tiene una constante elástica k. Asumiendo que la masa de la cuerda y del resorte son despreciables y no hay fricción en el eje de la polea, determina una expresión para la frecuencia angular de oscilaciones pequeñas. (En función de R, I ,m y k)

if the thermos has a vacuum innner, then heat through conv currents and conduction are reduced = vacuum flask

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.

the given statement is true.

sensory memory lasts for a fraction of seconds before the information is lost. it is the shortest -term memory and can be called as an element of memory. example: when we look at something and remember what it looks like, is just a second of observation. it degrades very quickly. it can also be considered as the process of perception rather than considering it as a memory.

if i am correct, your answer choices are:

a. the temperature remains constant

b. the temperature increases at a constant rate

c. heat flows at a constant rate into the system

d. heat flows at a constant rate out of the system

e. no heat flows into or out of the system

if so, then the answer is e. no heat flows into or out of the system.
