THEY WORK TOGETHER TO CREATE A TISSUE OR A WORKING ORGAN
Answer:
I think it's d) down the page
Answer:
t = 1
Explanation:
you dont know the value of the variable
1) sound velocity reported by you : 292.39 m /s
2) time to travel 1620m at that velocity: t = d / v = 1620 m / 292.39 m/s = 5.54 s, since the moment the sound wave started.
3) You might wanted to tell the time since you watched the lightning.
Then you can calculate the time since the lighting was generated,1620 m away from you, until you saw it, using the speed of light:
speed of light = 3*10^8 m/s => t = 1620 m / (3*10^8m/s) =0.0000054 s
Then, this time is completely neglectible, and yet the answer is 5.54 s, as calculated in the step 2.
Answer:
C
Explanation:
When light transitions from the air to the water the light bends due to refraction. The refractive index is related to the speed of light in both air and water. The Wikipedia article on Refraction does and excellent job of explaining this.
