What way would the balls fall? Top<br> Left<br> Right<br> Bottom
stira [4]
Each ball, when released, will fall toward the center of the big ball that everybody is standing on.

Another way to describe it:  Each ball, when released, will fall in the direction parallel to a line from the boy's head to his feet.

-- The ball held by the boy on top will fall toward the bottom of the picture.

-- The ball held by the boy on the right will fall toward the left side of the picture.

-- The ball held by the boy on the bottom will fall toward the top of the picture.

-- The ball held by the boy on the left will fall toward the right side of the picture.

In each case, the direction toward the center of the big ball that they're all standing on is the direction that each person calls "down".

An eagle flying at 31 m/s emits a cry whose frequency is 440 Hz. A blackbird is moving in the same direction as the eagle at 16
ankoles [38]

(a) The frequency the blackbird hears is 461.15 Hz.

(b) The frequency the blackbird hears after the eagle passes the blackbird is 422.35 Hz.

Given that, velocity of the eagle v₁ = 31 m/s

Frequency of the eagle F₁ = 440 Hz

Velocity of the blackbird v₂ = 16 m/s

Speed of sound v = 343 m/s

(a) The equation for frequency is given as F = f₀ (v-v₂)/(v-v₁)

F = 440 * (343-16)/(343-31) = 440 * 327/312 = 461.15 Hz

(b) The equation for frequency is given as F = f₀ (v+v₂)/(v+v₁)

F = 440 * (343+16)/(343+31) = 440 *359/374 = 422.35 Hz
