Because sound is a wave, it's possible to make a diffraction grating for sound from a large board of sound-absorbing material wi

th several parallel slits cut for sound to go through. When 9.0 kHz sound waves pass through such a grating, listeners 12 mfrom the grating report "loud spots" 1.3 m on both sides of center.
What is the spacing between the slits?

Use 340 m/s for the speed of sound.

What is the total current in the circuit? (must include unit - A) REWARD = BRAINLEST
Aleksandr-060686 [28]

Answer:6amperes

Explanation:

1/R=1/40 + 1/40

1/R=2/40

Cross multiplying we get

2R=40

Divide both sides by 2

2R/2 =40/2

R=20ohms

Current=voltage ➗ resistance

Current=120 ➗ 20

Current =6amperes
