If ball 1 has a higher speed than ball 2, then ball 1 has higher kinetic energy than ball 2, since kinetic energy is the energy of movement.
A scientific claim<span> can be a prediction that something will happen, based on a scientific theory or a hypothesis. A valid scientific claim is when t</span><span>he claim is supported by at least ten scientists in addition to the original researcher. Hope this answers the question. Have a nice day.</span>
Answer:
Explanation:
a ) y = A sin(B) ; here B is the phase of the wave which moves so that it remains constant
ωt - kx = constant
differentiating on both sides
ωdt - kdx =0
ωdt = kdx
dx / dt = ω / k
wave velocity = ω / k
b ) ω = 14.5 rad / s ,
k = 18 rad / m
wave velocity = ω / k
= 14.5 / 18
= .805 m /s
80.5 cm / s
c )
Amplitude = A
= 9.5 m
