I’m pretty sure it just wants you to list the property’s meaning the material and density
The one at the base would be much older due to the law of super position, and the rock at the top would be much newer,again, due to the law of super position.
The average speed is 42.7 m/s
Explanation:
The speed of an object in uniform motion (=moving at constant speed) is given by the equation:
where
v is the speed
d is the distance
t is the time
For the car in this problem, we have:
d = 2560 m (distance)
t = 60 s (time)
Solving the equation, we find the average speed:

You didn't actually include the speed of sound. But it doesn't matter for this question. If the trumpeter and the listener are on the same moving sidewalk then the distance between them is not changing. The Doppler shift only happens when the distance between the source and the Observer is changing. So the Listener hears the same 290 Hertz that the trumpeter is generating.
