Un trozo de metal de 12 gr, tiene una densidad de 4 /^3 y esta sumergido por medio de una cuerda en una pileta de aceite de densidad 1,5 /^3, como muestra la figura . ¿Cuánto vale la tensión de esa cuerda?

Which of the following changes to a pipe would increase the conductance by a factor of 12? 1.quadrupling the length and tripling the radius.2.reducing the length by a factor of and doubling the radius.3.tripling the length and reducing the radius by a factor of .4.reducing the length but a factor of and doubling the radius.

Pls pls pls pls ! describe, in your own words, how you found the epicenter of the earthquake.

Consider the growth of a 20-nm-diameter silicon nanowire onto a silicon wafer. the temperature of the wafer surface is maintained at 2400 k. assume the thermal conductivity of the silicon nanowire is 20 wm-1k-1 and all its surfaces including the tip are subjected to convection heat transfer with the coefficient h = 1×105 wm-2k-1 and t∞ = 8000 k. when the nanowire grows to l = 300 nm, what is the temperature of the nanowire tip (t (x =
