An alert driver can apply the brakes fully in about 0.5 seconds. How far would the car travel if it

Physics
1 answer:
dybincka [34]3 years ago
8 0

Answer:

The car would travel after applying brakes is, d = 14.53 m

Explanation:

Given that,

The time taken to apply brakes fully is, t = 0.5 s

The velocity of the car, v = 29.06 m/s

The distance traveled by the car in 0.5 s, d = ?

The relation between the velocity, displacement, and time is given by the formula                

                                d = v x t    m

Substituting the values in the above equation,

                                  d = 29.06 m/s x 0.5 s

                                     = 14.53 m

Therefore, the car would travel after applying brakes is, d = 14.53 m

Light propagates faster through a medium “A” than medium “b”
Serhud [2]

Answer:

1) The medium b has higher optical density.

2) If the optical densities of both A and B are same.

Explanation:

  1. The refractive index of a material determines the number of times the velocity of light in that material is slower than the velocity of light in a vacuum.
  2. The higher refractive index means slower propagation of the light in that medium.
  3. The refractive index of the medium determines the optical density of the medium.
  4. If the material has a higher refractive index, then its optical density is high.
  5. If the material has a low refractive index, then its optical density is low.
  6. The light bends towards the normal while refracting through the medium from a lower optical density medium to the higher optical density medium.
  7. If both the mediums has the same optical density, the direction of propagation doesn't change.

Help me please <br>only if you really know​
emmasim [6.3K]

Assume <em>R</em> is measured in meters (m) and <em>M</em> in kilograms (kg). Then

<em>R</em> ² / (<em>GM</em>) = [m]² / ([N•m²/kg²] [kg]) = m•kg / N = m•kg / (kg•m/s²) = s²

so <em>t</em> ² is indeed proportional to <em>R</em> ²/(<em>GM</em>).
