When light is passing from a denser medium to a lighter medium ( for example: from water to air)
<span> When the angle of refraction is greater than the critical angle( angle of incidence when the angle of refraction is perpendicular to the normal) of the denser medium.</span>
Answer:
3 up 1 across is the answer
Explanation:
Step one: find the Y intercept( Where the line cuts the y-axis)
X = 0
Y = 3(0) (p.s cross out the (o)
y = 2
Step 2: find the gradient (slope of the line)
rise = 3

The delta indicates a difference or change. such as delta y is the change in y position
Answer:
0.71121 km/s
Explanation:
= Velocity of planet initially = 54 km/s
= Distance from star = 0.54 AU
= Final velocity of planet
= Final distance from star = 41 AU
As the angular momentum of the system is conserved
When the exoplanet is at its farthest distance from the star the speed is 0.71121 km/s.
