Answer:
Refraction
Explanation:
Refraction is the change in direction of waves that occurs when waves travel from one medium to another. Refraction is always accompanied by a wavelength and speed change. Diffraction is the bending of waves around obstacles and openings.
Answer:
Explanation:
Look at the equation for Potential Energy. PE = mass times gravity times the height. Filling in and solving for h:
34.3 = .5(9.8)h so
34.3 = 4.9h so
h = 7 meters
Answer: I'm pretty sure that this one's just an opinion but I guess 3 meters so you have a chance to notice it and move or 1 meter so that it doesn't hit as hard when it lands.
