If i pushes a box that weighed 100 N across a 5 m distance, how much work did i do on the box.

w= 500 j

Explanation:

w= f*d

w= 100*5

w= 500

You did 500 Nm work on the box.

Explanation:

Work = Force applied x Distance

For an object to tend to move, the force applied must be equal or greater than the weight and coefficient of friction. Considering that the surface is smooth, therefore, the coefficient of friction is negligible.

Force Applied = 100 N

Distance = 5 m

∴ Work = 100 N * 5 m

            = 500 Nm

answer: the correct answer id option(d).

explanation:

snell's law refraction:

the angle of refraction =

the angle of incidence =

refractive index of air = = 1

refractive index of glycerol = 1.47

from the given options, the most closest answer to 63.72° is 65° of option (d).
