A 154-lb adult man performs a moderate level of physical activity and regularly consumes 2700 Calories a day. State whether the weight of the man will most likely decrease, increase, or remain the same. Use information from the data table to explain your answer.

pe = weightxheight = 2000x1000=2,000,000joules

grav force prop 1/r squared 2r all squared is 4rsquared 1/4rsquared quartered

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.
