Aship travels with velocity given by 12, with current flowing in the direction given by 11 with respect to some co-ordinate axes.
what is the velocity of the ship in the direction of the current?

Explanation:

Velocity of the ship is given as

the direction of the velocity of the ship is making an angle of 11 degree with the current

so we will have two components of the velocity

1) along the direction of the current

2) perpendicular to the direction of the current

so here we know that the component of the ship velocity along the direction of the current is given as

answer: the correct answer id option(d).

explanation:

snell's law refraction:

the angle of refraction =

the angle of incidence =

refractive index of air = = 1

refractive index of glycerol = 1.47

from the given options, the most closest answer to 63.72° is 65° of option (d).

i do.
