Question 19 of 25 Which statement explains how constructive interference supports the wave
model of light rather than the particle model?
A. Two beams of light intersect, canceling each other out and
forming a weaker beam, which is a behavior of waves.
B. Light waves bend around a corner, but particles would not travel in
bent paths.
C. Light strikes a metal surface and knocks electrons loose, which
particles would not do.
D. Two light beams intersect, joining together to form a brighter
beam, which is a behavior of waves.

This problem has been solved! see the answera non-uniform fire escape ladder is 6.0m long whenextended to the icy alley below. it is held at the top by africtionless pivot, and there is neglibible frictional force fromthe icy surface at the bottom. the ladder weighs 250n, and it'scenter of gravity is 2.0m along the ladder from the bottom. amother and child of total weight 750n are on the ladder 1.5m fromthe pivot. the ladder makes an angle θ with the horizontal.find the magnitude and direction ofa) the force exerted by the icy alley on the ladderb) the force exerted by the ladder on the pivotc) do your answers in part a and b depend on the angle?

The image shows the positions of a car on a roller coaster track. arrange the cars in order based on their gravitational potential energy. begin with the lowest potential energy and end with the highest.

Assume this car is driven off a cliff . how many arrows of force need to be drawn in the free body diagram? assume no air resistance -five -one -three -four
