 t = t₀ / 2

Explanation:

In this exercise we must use Newton's second law

         F = m a

         a = F / m

now we can use kinematics

 as in object part of rest (v₀ = 0)

       v =a t₀

       t₀ = v / a

these results are with the first experiment

now repeat the experiment, but F = 2F₀

          a = 2F₀ / m = 2 a₀

         v = 2 a₀ t

         t = v / 2a₀

         t = t₀ / 2

Large birds like pheasants often walk short distances. Small birds like chickadees never walk. They either hop or fly. Why might
nevsk [136]

Answer:

Large birds can't fly due to higher weight and weak wings.

Large birds like pheasants often walk short distances whereas small birds like chickadees never walk but fly because the large birds have more weight which can't support by the wings to fly in the sky so they walk on the land instead of flying.

While on the other hand, small birds have lower weight and easily fly in the sky so they don't need to walk on the ground so we can conclude that large birds can't fly due to higher weight and weak wings.
