Answer:
Vertical = 21.2 m/s
Horizontal = 21.2 m/s
Explanation:
For the vertical component:
sin (45) = v/30
sin (45) x 30 = v
21.2 m/s = v
For the horizontal component:
cos (45) = h/30
cos (45) x 30 = h
21.2 m/s = h
Answer: The amplitude is 0. (assuming that the amplitude ot both initial waves is the same)
Explanation:
When two monochromatic light waves of the same wavelength and same amplitude undergo destructive interference, means that the peak of one of the waves coincides with the trough of the other, so the waves "cancel" each other in that point in space.
Then if two light waves undergo destructive interference, the amplitude of the resultant wave in that particular point is 0.

Answer: work
Explanation:
Often in physics, work is defined as the use of force to move an object. Technically, work is actually a change in energy caused by a force external to the system. The formula for work is W = F⊥d or W = FdcosΘ. Using this formula, we can see that work is just when a force is applied for a certain displacement. In simpler terms, that's just a force used to move an object a certain distance.
