Un bloque con una masa de 2.6 kg está unida a un resorte horizontal con constante elástica k = 6.7x102 N/m. Si el bloque se jala hasta 41.2 cm y se suelta, ¿cuál es la variación de energía potencial elástica? Despreciar la fricción entre la superficie y el bloque

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length (in m) of a column of water 1.45 km high for a temperature increase of 1.12°c. assume the column is not free to expand sideways. as a model of the ocean, that is a reasonable approximation, as only parts of the ocean very close to
