Answer:
T = 5.36 s
Explanation:
given,
depth of the mine shaft = 122.5 m
speed of the sound = 340 m/s
time taken = ?
time taken by the stone to reach at the bottom
using equation of motion
initial speed , u = 0 m/s
t = 5 s
time taken by the sound to travel
d =v x t
t = 0.36 s
total time taken for the sound to reach carol after dropping the stone
T = 5 + 0.36
T = 5.36 s
Answer:
the velocity of the water flow is 7.92 m/s
Explanation:
The computation of the velocity of the water flow is as follows
Here we use the Bernouli equation
As we know that
= 7.92 m/s
Hence, the velocity of the water flow is 7.92 m/s
We simply applied the above formula so that the correct value could come
And, the same is to be considered
Answer:
lowest level contains more energy
Explanation:
<span>The
answer is X-rays.<span> </span>Chandra observes the universe
in X-ray vision. The observatory has helped astronomers discover black holes,
dark matter, quasars, and supernovas and see beyond regions in the universe past
that have high temperatures and very high
luminosity. It has allowed us to see the
universe beyond our visual capacity (visible light of the electromagnetic spectrum).
