Si en un balancín la fuerza F es de 50 Newtons y se aplica a 1 metro de distancia del fulcro. ¿Cuántos Newtons tendría que valer la resistencia R para que el balancín esté en equilibrio si ésta (R) se encuentra a 0,5 metros del punto de apoyo?

When a formula is solved for a particular variable, several different equivalent forms may be possible. if we solved a=1/2bh for h, one possible correct answer is h=2a/b . which one of the following is not equivalent to this? a. h= 2(a/b) b. h= 2a(1/b) c. h= a/1/2b d. h= 1/2a/b
