Answer:
the speed of the sound in the air is 343.3 m/s
Explanation:
The computation of the speed of the sound in the air is shown below:
As we know that
Speed = Distance ÷ time
So, here speed be 515 m
And, the time is 1.50 seconds
So, the speed of the sound is
= 515 m ÷ 1.50 seconds
= 343.3 m/s
hence, the speed of the sound in the air is 343.3 m/s

Answer: The soil will be
warmer than the water.
Explanation:
The heat (thermal energy) absorbed can be found using the following equation:
Where:
is the heat
is the mass of the element
is the specific heat capacity of the material.
is the variation in temperature
<u>In the case of soil we have:</u>
(1)
Where:


<u>In the case of water we have:</u>
(2)
Where:


Isolating
from both equations:
(3)
(4)
(5)
(6)
Comparing (4) and (6) we can find the soil will be
warmer than the water.
