Answer:
Refractive index of unknown liquid = 1.56
Explanation:
Using Snell's law as:
Where,
is the angle of incidence ( 65.0° )
is the angle of refraction ( 53.0° )
is the refractive index of the refraction medium (unknown liquid, n=?)
is the refractive index of the incidence medium (oil, n=1.38)
Hence,
Solving for
,
Refractive index of unknown liquid = 1.56
I associate "Tone" with sound frequencies. Tonic solfa being a music example which is basically, I think, using a certain musical key signature such as C major. In a major scale the sequence of "musical intervals" (ie frequency steps) is key note TONE TONE SEMITONE ... TONE TONE SEMITONE.octave higher than keynote.
So, I'd go for a here.
Answer:
i believe he threw the ball up at about 18 mph
Explanation:
Answer:
power will three times decrease (one-third)
Explanation:
P = W / t
thus when work is constant, power is inversely proportional to time
so, when time is tripled, power is decreased to one-third
