It would be B. since the scanning shows what the terrain is down there
(I listened)
I think d because the water can make the humidity go down and make the air cool
Answer:
89 m
Explanation:
Applying
v = 2d/t................... Equation 1
Where v = velocity of sound in air, d = distance of the wall from Karen, t = time taken to hear the echo.
make d the subject of equation 1
d = vt/2..................... Equation 2
From the question,
Given: v = 343 m/s, t = 0.519 s
Substitute these values into equation 2
d = (343×0.519)/2
d = 89.01 m.
d ≈ 89 m
The reason why the reaction takes place faster when the
temperature is higher is that the collision of particles of the object
increases. In order to have a faster reaction, you would need the particles of
the object to get excited and increase its collision to other particles. This
can be achieved through increasing the temperature.
-55 C to F is -67.
I hope this helps you!
Brainliest answer is always appreciated!
