You are driving down the highway late one night at 20 m/swhen a deer steps onto the road 35m in front of you. your reaction time before stepping on the brakes is 0.50s, and the maximum deceleration of your car is 10m/s2. how much distance is between you and the deer when you come to a stop? you found the distance that you will cover while braking. you can use the expected amount of time for braking to check your answer for distance. using the information given in the introduction and the value for distance that you found above, determine the time required for you to stop once you press the brakes. note that the time for braking is just the time interval t3? t2.

a. is the answer because they are not shared

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

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.
