Answer:
<h2>50
°</h2>
Explanation:
Angle of rotation of the flat polished surface 
= 15°
angle of incidence i = 20°
Since the polished surface is turned at an angle of 15°, the angle of reflection
r = 2 (Note that the angle of rotation only have effect of the angle of reflection)
r = 2*15 = 30°
The angle between the reflected ray and the incident ray will be equal to the sum of the angle of incidence and the angle of reflection i.e i+r
The angle between the reflected ray and the incident ray = 20°+ 30° = 50°
Answer:
False
Explanation:
The collaborative learning is not a type of learning that focuses on individual learning. This type of learning focuses on joint learning between two or more individuals that act as a team. The collaborative learning is a method that encourages the two or more individuals to work together, to capitalize on each other's skills and resources for the benefit of the whole, for the team. This type of learning has its own supporters and critics, as some consider it as excellent way to develop the team work and closer bonds between the people, while others argue that it is destroying the potential of the individual.

Answer:
Explanation:
Find the final velocity at which it struck the ground by using the kinetic energy formula.
Now use kinematics to solve for the vertical displacement. We were given the initial velocity and acceleration can be assumed to be 9.8
Δy = 13.6 meters
