Calcular el ángulo de refracción de un rayo luminoso que está en un ambiente de índice 4 y pasa a un ambiente de índice 3 incidiendo con un ángulo de 37°

answeridentity;

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
