Answer:
Step-by-step explanation:
Given
Required
Determine the acceleration
This question will be answered using the first equation of motion.
Substitute values for v, u and t
Subtract 20 from both sides
Divide both sides by 4
<em>Hence, the acceleration is 10m/s/s</em>
Y = 8 and X is 5 that’s the answer to your question
Your answer for air is correct. Glass has a higher refractive index compared to water.
So the answers should go in this order: Water, Glass, Air
Explanation:
Light moves slower in glass, so glass has a higher refractive index than water. This means that light is refracted at a greater angle
8352. Multiply 20880 by 2 then divide by 5.
