Answer:
Temperature when sound wave with wavelength 0.47m has frequency 741 hz is 188 degrees Centigrade.
Step-by-Step Explanation:
Given:
Speed of sound at 0 degrees centigrade = 235 ms
frequency = f = 741 hz
wavelength = w = 0.47m
speed of sound wave = wavelength * frequency = 741 * 0.47 = 348.27 m/s
Using the formula for speed of sound at a specific temperature:
Speed of sound at T degrees Centigrade = Speed of sound at 0 degrees + 0.6 * T
When speed of sound is 348 m/s, the temperature is given by:
348 = 235 + 0.6(T)
T = (348-235)/0.6
T = 188 degrees Centigrade
The watts determine the brightness. Watt is the unit of Power. And Power is equal to Voltage x Amps (current). So both the current and voltage determine the brightness.
4 significant figures (the 0’s are considered significant because they follow a non-zero number)
