Answer:
Explanation:
The light from these little disks is also refracted by Earth's atmosphere, as it travels toward our eyes. That's because, in the direction of any horizon, you're looking through more atmosphere than when you look overhead. If you could see stars and planets from outer space, both would shine steadily.

Answer: F=32.2m</h2>
Explanation:
According Newton's 2nd Law of Motion the force 
is directly proportional to the mass 
and to the acceleration 
of a body:
(1)
When we talk about the force of gravity on an object (the weight) the constant acceleration is due gravity, this means:
(2)
Substituting (2) in (1):
(3)
This means the equation that best represents the force on an object due to gravity according to its mass, among the given options is:
Answer:
Vy = V sin theta = 30 * ,574 = 17.2 m/s
t1 = 17.2 / 9.8 = 1.76 sec to reach max height
Max height = 17.2 * 1.76 - 1/2 * 4.9 * 1.76^2 = 15.1 m
H = V t - 1/2 g t^2 = 1.2 * 9.8 * 1.76^2 = 15.1 m
Time to fall from zero speed to ground = rise time = 1.76 sec
Vx = V cos 35 = 24.6 m / sec horizontal speed
Time in air = 1.76 * 2 = 3.52 sec before returning to ground
S = 24.6 * 3.52 = 86.6 m
Answer:
yes, radio waves and x-rays are type of light.
