Water in the atmosphere and within the clouds themselves cause light waves to refract and reflect, creating an assortment of colors. The patterns occur when light is absorbed by water droplets within the clouds. The amount of absorption that occurs depends on the temperature of the air. The patterns occur when light is reflected from water droplets within the clouds. The amount of reflection that occurs depends on the wavelength of the light, and shorter wavelengths are reflected at a greater angle than longer ones.
Hope this helps!!
22.5 m/s
This is because the puck will not slow down, and maintain a constant velocity.
Answer:
Explanation:
hence making time the subject then
Substituting 50 cm which is equivalent to 0.5 m for distance and velocity as given as we obtain
From kinematic equation
and taking g as 9.81 then
Answer:
Height of ramp = 17.49 m
Explanation:
We have equation of motion , , s is the displacement, u is the initial velocity, a is the acceleration and t is the time.
Considering horizontal motion of skier
Initial velocity = 33 m/s, Displacement = 63 m, acceleration = 0 and we need to find time taken to reach ground by the skier.
The vertical distance traveled in 1.909 seconds is the height of ramp
Initial velocity = 0 m/s, acceleration = acceleration due to gravity = 9.8 , time = 1.909 s and we need to find displacement.
So height of ramp = 17.49 m
The total distance is 60*2-15=105 kilometers, and the total displacement is 15 kilometers east.
