An inclined plane has a ramp length of 4.0 meters and a height of 2.0 meters. what is the ima of the inclined plane? 0.5 2.0 6.0 8.0

Length of the ramp (L) = 4.0 m = Distance traveled by the effort

Height of the inclined plane (h) = 2.0 m = Distance traveled by the resistance

IMA = Ideal mechanical advantage

IMA = 2.0

Hence, the IMA of the inclined plane is 2.0

a=d/t

a="triangle"v/t

explanation:

a = acceleration

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.
