Explanation:
Explanation is given in the attached document.
Answer:
1 ) Warm air
2) Cold air
3) Cold water
4) Steel
5) Hot molten
Explanation:
In order to solve this problem, we have to warn that the sound propagates more easily in denser media, in this way we have to identify the densities of the different materials.
Density cold air = 1.2 [kg/m^3]
Density warm air = 1.01 [kg/m^3]
Density cold water = 1000 [kg/m^3]
Density steel = 7500 [kg/m^3]
Density hot molten = 14100 [kg/m^3]
Therefore in order from the slowest to the fastest:
1 ) Warm air
2) Cold air
3) Cold water
4) Steel
5) Hot molten
Meerkat is incorrect but correct the answer is 15 and yes this can be explaned by Newton’s third law of motion for every action there is an equal or opposite reaction
Your welcome and have a great day. :p
Answer:
-88 °C
Explanation:
Charles' law is derived from the ideal gas law. The ideal gas law says:
PV = nRT
If n and P are constant, then we get Charles' law:
V₁ / T₁ = V₂ / T₂
Plugging in values and solving:
(125 L) / (35 + 273 K) = (75 L) / T
T = 185 K
T = -88 °C
