Answer:
38 m/s
Step-by-step explanation:
We are given that
D represent Rachel's remaining distance( in meters ) as a function of time is given by
We have to find the Rachel's speed.
We know that
Substitute the values then we get
Hence, the Rachel's speed is given by =38 m/s
To the right is postive so negive numbers with be on the left and 7 will be above 0 so locate 3 backwards from 0 and go up 7
Answer:
8 sandwiches
Step-by-step explanation:
When light moves from one medium to another, it is refracted. If it moves from a medium with refractive index n1 to one with refractive index n2, with an incidence angle to the surface normal of θ1, the refraction angle θ2 can be calculated from Snell's law.
The Snell's law states that the ratio of the sines of the angles of incidence and refraction of a wave (in this case beam/light) are constant when it passes between two given media.
Given that a <span>laser travels from glass to water at an angle of 35° with the normal, </span>
<span>. If water has an index of refraction of 1.33 and glass has an index of refraction of 1.52, then we have:
