Answer:
A) Speed
Explanation:
The medium of transmission(air) does not change before and after reflection. The sound still travels in air after the reflection. i.e the medium of transmission of sound is constant.
Since the medium of transmission remains constant, speed also remains constant. Speed only changes when the medium of transmission changes.

From the deepest ocean trench to the tallest mountain, plate tectonics explains the features and movement of Earth's continents/ surface in the present and the past. Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle called convection, the rocky inner layer above the core which has a high density.

Answer:
Using the grid, graph, and given data, estimate the distance traveled by the walker during the two hour interval from t= 0 t = 0 to t= 2. t = 2. You should use time intervals of width Δt= 0.5.
