Answer:
23 mi
Explanation:
Let us first record all the values we have
acceleration = 4 ft/s
max speed = 90 mi/hr * 1 hr/3600s * 5280 ft/1 mi = 132 ft/s
We can use the equation of linear motion since acceleration is constant
distance covered = distance during acceleration + distance during costant
velocity
distance in miles = 120 978 ft * 1 mi/5280 ft = 22.9125 mi ≈ 23 mi
Answer:
critical angle is the angle of incidence in optically denser medium, for which the angle of reflection in the less denser medium is 90 degree
Explanation:
total internal reflection occurs at one particular angle of incidence where the reflected ray lies on the boundary.
this angle is called the critical angle
