Check the picture below.
now, for 6 triangles, well, simply 6*6.
It indicates that you should proceed with caution. You should slow down and be prepared to stop to safely navigate this intersection.
Answer:
The refracted light wave is bent at an angle while the reflected light wave is bounced back either at 90° or at angle less than 180°.
The refracted light wave changes its speed when it moves from one medium to another based on the density of the medium.
The reflected light does not change its speed once it contacts another medium. It just bounces back with the same speed.
Explanation:
Answer:
n = 1.76
Explanation:
According to the rule of ( n1 sin theta1 = n2 sin theta2 )
we know both angles so we insert them to the law and apply n1 = 1
so 1/2 = n2 sin 62 and we get the final answer
Answer:
The correct option is propped cantilever beam.
Explanation:
A propped cantilever beam along with all the reactions is shown in the attached figure.
Since we can see that the number of unknowns are 4 but the equations of statics are only 3 thus we conclude that the beam is indeterminate to 1 degree.
For all the other beams the reactions and the equations are 3 each thus making the system determinate.
