You adjust the temperature so that a sound wave travels more quickly through the air. You increase the temperature from 30 degre
katen-ka-za [31]
To calculate the velocity of the sound wave, we use this formula:
V = 331 + [0.6*T], 
Where V is the velocity and T represents temperature.
When the temperature is 36 degree Celsius, we have 
V = 331 + [0.6 * 36]
V = 331 + 21.6 = 352.6 
Therefore, V = 352.6 m/s.

The height of the Washington Monument is measured to be 170.00 m on a day when the temperature is 35.0°C. What will its height b
N76 [4]

Answer:

169.98 m

Explanation:

\alpha = Thermal coefficient of marble = 2.5\times 10^{-6}/^{\circ}C

L_0 = Initial length = 170 m

\Delta T = Change in temperature = (-10-35)°C

Change in length is given by

\Delta L=\alpha L_0\Delta T\\\Rightarrow \Delta L=2.5\times 10^{-6}\times 170\times (-10-35)\\\Rightarrow \Delta L=-0.019125\ m

The height on the given day will be 170-0.019125=169.98\ m
