Una cuerda se enreda alrededor de un poste telefónico, formando sus dos extremos un ángulo de 120° (como se ve en la figura). Si de uno de los extremos se tira con una fuerza de 85 Kg y
del otro con una fuerza de 30 Kg. ¿Cuál es el valor de la fuerza resultante sobre el poste y su
dirección (ángulo) respecto a la fuerza de 85 Kg?

The pressure increases by 1.0 x 104 n/m^2 for every meter of depth beneath the surface of the ocean. at what depth does the volume of a pyrex (bulk modulus 2.6 x 1010n/m^2) glass cube, 9.8 x 10^−2m on an edge at the ocean's surface, decrease by 7.5 x 10−10m^3? explain the formula beyond this point: p=1.0x10^4, b=2.6x10^10, l=9.8x10^−2, delta v=7.5x10^−10. at some point l needs to be cubed. why p is divided by delta v?

When electrons are added to the outermost shell of a carbon atom, it forms--an anion that has a larger anion that has a smaller cation that has a larger cation that has a smaller radius.
