Explanation:
Estrictamente hablando, las leyes de movimiento de Newton son válidas solo en un sistema de coordenadas en reposo con respecto a las estrellas "fijas". ... Un sistema de coordenadas unido a la Tierra no es un marco de referencia inercial porque la Tierra gira y se acelera con respecto al Sol.
Answer:
to turn red litmus blue and react with acid to form salt
Answer:
Explanation:
Let the critical angle be C .
sinC = 1 / μ where μ is index of refraction .
sinC = 1 /1.2
= .833
C = 56°
Then angle of refraction r = 90 - 56 = 34 ( see the image in attached file )
sin i / sinr = 1.2 , i is angle of incidence
sini = 1.2 x sinr = 1.2 x sin 34 = .67
i = 42°.
The tendency of a material to oppose the flow of charge is called: B) resistance
