To represent in order how the animals
Answer:
The angle of incidence is the angle between this normal and the incident ray; the angle of reflection is the angle between this normal and the reflected ray. According to the law of reflection, the angle of incidence equals the angle of reflection.

The time taken by a person that is walking at 2 meters per second to travel 1200 meters is 600 s
v = d / t
v = Velocity
d = Distance
t = Time
v = 2 m / s
d = 1200 m
t = d / v
t = 1200 / 2
t = 600 s
Velocity is the rate of change of distance with respect to time. It is denoted using V. Its unit is usually m / s.
Therefore, the time taken by thy person is 600 seconds

The gravitational potential energy of an object, measured with respect to the ground, is given by

where m is the object's mass, g is the gravitational acceleration and h is the height of the object measured from the ground.
In our problem, the mass of the plane is m= 5 tons = 5000 kg, while the potential energy is

so we can re-arrange the previous formula and use these data to calculate h, the height of the airplane:
