Answer:
The temperature is 419,1 K
Explanation:
We use the formula PV=nRT T=PV/nR
T=1,5 atm x 12,6 L/0,55 mol x 0,082 l atm/K mol
T= 419,0687361 K
Answer:
57.8kg
Explanation:
Potential energy is given by:
Where U is potential energy, m is mass, g is acceleration due to gravity, and h is height. Using this equation:
The answer is A. The vibration caused by the waves through the air eventually weaken, which is why sound diminishes easily over distance.
Since plants turn sunlight into glucose (sugar) that humans and animals eat... the energy we get from our food comes indirectly from the sunlight.
