Speed of sound in cold air < Speed of sound in Warm air < Speed of sound in hot molten lead < Speed of sound in water
Explanation:
Step 1:
Speed of sound in water varies from 1450 to 1498 meters per second
Speed of sound in Hot Molten lead is approximately 1210 meters per second
Speed of sound in warm air is approximately 338.89 meters per second
Speed of sound in cold air is approximately 293.33 meters per second
Step 2:
In warm air sound travels faster than that of sound travelling nature in cold air.
∴ Speed of sound in cold air < Speed of sound in Warm air < Speed of sound in hot molten lead < Speed of sound in water
Speed of sound in cold air the slowest while Speed of sound in water is the fastest mean.

Answer:
the distance between the lawyer's home and her office is 124 miles
Explanation:
given information:
first lets assume that
x-axis (west = positive, east = negative)
y-axis (north = positive, south = negative)
thus,
distance of the house = (-88,18)
distance of the office = (13, -54)
thus, the distance between the lawyer's home and her office
R = √(x₂ - x₁)² + (y₂ - y₁)²
= √(13 - (-88))² + (-54 -18)²
= 124 miles
<h2>
Option 1 is the correct answer.</h2>
Explanation:
Power of heater, P = 1790 W
Time used, t = 24 hours = 24 x 60 x 60 = 24 x 3600 s
We have the equation
![\texttt{Power}=\frac{\texttt{Energy}}{\texttt{Time}}](https://tex.z-dn.net/?f=%5Ctexttt%7BPower%7D%3D%5Cfrac%7B%5Ctexttt%7BEnergy%7D%7D%7B%5Ctexttt%7BTime%7D%7D)
We need to find energy,
Substituting
![\texttt{Power}=\frac{\texttt{Energy}}{\texttt{Time}}\\\\1790=\frac{\texttt{Energy}}{24\times 3600}](https://tex.z-dn.net/?f=%5Ctexttt%7BPower%7D%3D%5Cfrac%7B%5Ctexttt%7BEnergy%7D%7D%7B%5Ctexttt%7BTime%7D%7D%5C%5C%5C%5C1790%3D%5Cfrac%7B%5Ctexttt%7BEnergy%7D%7D%7B24%5Ctimes%203600%7D)
Energy = 1790 x 24 x 3600 J
Option 1 is the correct answer.
