A locomotive with two carriages drives out of the station. The locomotive has a mass of 3.0 tonnes, and each of the two wagons h

as a mass of 2.0 tonnes. The force that accelerates the locomotive is 17.5 kN. We assume that there is no friction.
a) Calculate the acceleration of the train
b) Draw the forces acting on the middle carriage as the train accelerates
c) Calculate the magnitude of the forces acting on the middle carriage during acceleration

If the index of refraction for a certain glass is 1.5, and the angle of refraction is 15 degrees for a ray of light
LiRa [457]

Answer:

\theta_i = 23^o

Explanation:

The refractive index of a medium is given by the following formula:

\eta = \frac{Sin\theta_i}{Sin\theta_r}

where,

η = refractive index = 1.5

\theta_i = angle of incidence = ?

\theta_r = angle of refraction = 15°

Therefore,

1.5 = \frac{Sin\theta_i}{Sin15^o}\\\\Sin\theta_i=(1.5)Sin15^o\\\\\theta_i = Sin^{-1}(0.388)\\\\

\theta_i = 23^o
