Al deslizar un bloque de madera de 50 kg sobre una superficie horizontal aparece una fuerza de fricción entre las superficies de 98.1 N. ¿Hallar el valor del coeficiente de fricción? *

The california mussel (mytilus californianus) attaches itself to a rock or other solid surface with a bundle of filaments known as the byssus. imagine that 15.0 j of work is done to stretch the distal end of the byssus. it releases 10.8 j of thermal energy as it relaxes. what is the resilience of the distal end of the byssus?

Which best describes the difference between internal and thermal energy?
