Answer:

B.the speed at which the disturbance propagates

a great example would be sound. In air, the speed of sound is about 343m/s, but in iron, the speed of sound is about 5120 m/s that's about 15 times faster than air. Why is this? Well, it is because in the air the molecules are very spread out and have a long way to travel before they can bump their neighbors. But in iron, the molecules are much much closer and have a shorter distence before they hit their neighbors.

Acceleration = final velocity - initial velocity/time taken
A = Vf-Vi/t
A = 1 m/s - 0 m/s / 4 sec
A = 1 m/s / 4 sec
A = 0.25 m/s2

A rocket near the surface of the earth is accelerating vertically upward at 10 m/s2. The rocket releases an instrument package.

Hoochie [10]

Answer:

b)10 m/s^2 up

Explanation:

Immediately after The release from the rocket the acceleration of the instrument package will be same as of the rocket that is 10m/s^2 upward.

This because of newtons law of inertia. The states that a body in state of rest and state of motion will remain in state of rest or motion until and unless any external force is applied on it. Immediately after being released from the rocket inertia will keep the acceleration same. The effect of gravity come gradually.
