Answer: Resonance in sound is when one object is vibrating at the same frequency to the second object of forces to the second frequency.
Explanation:
"Acoustic resonance is a phenomenon in which an acoustic system amplifies sound waves whose frequency matches one of its own natural frequencies of vibration (its resonance frequencies)." wikipedia I hope this helps you!
The distance the bird flies is (17,000 + 600 + 14,400) = 32,000 km.
His average speed is (32,000 km)/(122 days) = 262.3 km/day.
The bird ends up (17,000 - 600 + 14,400) = 30,800 km north
from where he started.
His average velocity is (30,800 km)/(122 days) = 252.5 km/day north .
Answer:
D. He did not multiply the chlorine and oxygen atoms by the coefficient 4.
Explanation:
Answer:
Ionic compound
Explanation:
Barium Chloride is an ionic compound of barium and chlorine.
Barium is a metal with two valence electrons while chlorine is a non metal with seven valence electrons.
Barium will require two atoms of chlorine to form Barium chloride.
The reaction can be demonsated in the equation below.
Ba2+ + Cl- -----------> BaCl2
In this type of bond, Barium uses its 2 valence electrons to form an ionic bond with 7 valence electrons of chlorine. Chlorine will require its own two atoms to form this type of bond with Barium.
Cl -Ba-Cl = BaCl2
