The red end of the visible spectrum has the longer wavelength while the blue end of the visible spectrum has the higher frequency.
Answer:
w= p∆v 50000 ( 0.55-0.40) and calculate and you get it
The ears are superior and posterior to the shoulders and lateral to the nose.
At its maximum height, the ball will have zero vertical velocity, so the ball's velocity at this point is exactly equal to its horizontal velocity.
At any time <em>t</em>, the horizontal component of its velocity is
<em>v</em> = (15 m/s) cos(40°) ≈ 11.49 m/s
so at the highest point of its trajectory, the ball has a velocity of about 11.49 m/s pointed in the positive horizontal direction.
