Aloudspeaker located in air generates sound waves of frequency 1,000 hz. some of these sound waves enter a pool of water, where the speed of sound is 1,400 m/s. what is the wavelength of the sound waves in water?

1.4 m

Explanation:

v = Speed of sound in water = 1400 m/s

f = Frequency of sound = 1000 Hz

= Wavelength

When we multiply the frequency and the wavelength of a wave we get the velocity of sound in that medium

The wavelength of the sound waves in water is 1.4 m

question1

1,000 tons

question2

3: 8

question 3

store d

step-by-step explanation:

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
