Best answer will be 60

13) v=c/n for c, round to 300,000 km/sec

the speed of light in a material is calculated by dividing the speed of light in a vacuum by the index of refraction in the material.

calculate the speed of light in water which has a refraction rate of 1.33. showing your work is not necessary.

14) v=c/n for c, round to 300,000 km/sec

the speed of light in a material is calculated by dividing the speed of light in a vacuum by the index of refraction in the material.

calculate the speed of light in glass which has a refraction rate of 1.50

showing your work is not necessary.

the answer is d. 4

hope this

also the more points you give the faster your questions get answered

i dont think you are wrong for wanting to get even with someone who did you wrong.

(i'm an eye for an eye kind of person) but if this person hurt you in a sexual way, i dont suggest doing anything to him. he should be taken to the proper authorities, you could go to jail depending on what you do. if it was something small like your sibling took your spot on the couch, than yea, i would get even with him by taking one of his favorite snacks lol. but i dont suggest you doing anything illegal.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
