PLEASE HELP ME WITH THIS ONE QUESTION A tuning fork of 500 Hz is struck in a room with a speed of sound of 340 m/s. What is the distance between a point of rarefaction and the next compression point, in the resulting sound?

Wavelength = 0.68 meters.

Explanation:

Wavelength gives the distance between a point of rarefaction and the next compression point, in the resulting sound.

Given the following data;

Frequency = 500 Hz

Speed of sound = 340 m/s

To find the wavelength;

Wavelength = speed/frequency

Wavelength = 340/500

Wavelength = 0.68 meters

hey , the answer is c

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.
