Answer:
378 Hz
Explanation:
When source of sound moves away from stationary listener
f' = f x V / ( V + Vs)
f' = 600 x 340 / ( 340 + 200)
f' = 204000/540
f' = 378 Hz

Answer:
2
Explanation:
Step 1: RxN
4Al + 3O₂ → Al₂O₃
Step 2: Balance RxN
We have 4 Al's and 6 O₂'s on the reactant side.
We need the same number of Al's and O₂'s on the product side.
4Al + 3O₂ → 2Al₂O₃
