Answer:
Explanation:
Ignore air resistance
The horizontal velocity is
vx =19cos37.2 = 15.134 m/s
The ball travels 30 m in a time of
30 / 15.134 = 1.982 s
In that time, the ball will be at an altitude of
s = vy₀t + ½at²
s = 19sin37.2(1.982) + ½(-9.8)1.982² = 3.5137... m
so the ball clears the bar by
h = 3.5137 - 3.05 = 0.4637... = 0.46 m
Aristotle believed that the Earth was orbited by the sun, moon, and the other planets which he referred to as Celestial Bodys
The simplest answer is that gravity is the field created by a mass distribution in the spacetime around it; gravitational force is the force exterted by the field on a test mass in the field.
The answer would be A because as you get further away from sound the intensity decreases.
When energetic UV rays dissociates molecules of oxygen into seperate atoms. But when they collide into each other it forms OZONE.
