For each route from Boston to Detroit, there are 6 possible routes to Los Angeles.
Therefore if there are 4 routes from Boston to Detroit, the number of routes from Boston to Los Angeles is
4*6 = 24
The diagram shown below illustrates the possible routes.
Answer: 24
Net force can help slow down or stop the motion of an object.
Answer:
ni sin theta i = nr sin theta r where theta i is the angle of incidence and theta r the angle of refraction
For nr greater than ni (air to water) theta r must be smaller and the image would be bent towards the normal
the answer to this question is B
