Friction pushes her hands!!
KE = half of mass times squared speed
18 = 0.5 * mass * (3m/s)^2
18 = 4.5 mass
mass = 18 / 4.5 = 4 kg
The circuit component the symbol represents is: C) Battery
Answer: The light bends because light travels fast but it slows down in a denser medium. For example light refracts in water or it bends after passing through air. When light passes through air ( a less dense medium ) then through water ( a more dense medium ) the beam of light bends because light travels more slowly in a denser medium then it picks up its pace again once it passes. The density of the substance determines how much the light is refracted. I hope this makes sense and I hope this answered your question!! :)
