The final temperature is 34.91°C
<u>Explanation:</u>
<u></u>
Initial volume, V1 = 362m³
Final volume, V2 = 632m³
Initial temperature, T1 = 20°C
Final temperature, T2 = ?
We know,
V1/T1 = V2/T2
362/20 = 632/T2
T2 = 34.91°C
Therefore, the final temperature is 34.91°C
Answer:
decreases
Explanation:
The angular frequency of the mass is given by
where, k is the spring constant and m be the mass of the body which is doing oscillations.
if the mass of the body increases, so the value of angular frequency decreases, as the angular frequency is inversely proportional to the square root of the mass of the body.
Answer:
i) 2
ii) No
Explanation:
i) The man will hear two sounds: one through the rail, and one in the air.
ii) The sounds will not reach the man at the same time. Sound travels faster through solids than through gases, so he will hear the sound through the rail before he hears the sound in the air.
Gravity? Gravity should create a centrifugal force.
