Answer:
1) Superposition results in adding the two waves together. Constructive interference is when two waves superimpose and the resulting wave has a higher amplitude than the previous waves. Destructive interference is when two waves superimpose and cancel each other out, leading to a lower amplitude.
I'm sorry thats all I can help with
Away from all people? It’s safest
-I could be wrong but I am pretty sure since you wouldn’t point something dangerous towards others :/
1) Resultant force:
The two forces have same magnitude (4 N) but opposite verse, so their resultant is zero:
2) Couple
The two forces have opposite direction and they are applied at a distance d=0.2 m from the center of the square, so they generate a couple equal to the sum of the torques generated by each force:
Answer:
1.4 billion light years away
Explanation:
v = Recessional velocity = 30000 km/s[/tex]
= Hubble constant =
D = Distance to the galaxy
According to Hubble's law
The galaxy is 1.4 billion light years away
Explanation:
Acceleration is change in velocity over time.
a = Δv / Δt
a = (18.0 m/s − 0 m/s) / (6.00 s)
a = 3.00 m/s²
Momentum is mass time velocity.
p = mv
p = (8000 kg) (18.0 m/s)
p = 144,000 kg m/s
