Answer: When you cannot stop safely at a yellow traffic light before entering an intersection, enter the intersection carefully and continue across.
Explanation: To find the correct answer, we need to know more about the traffic signal rules.
<h3>What is the traffic signal rules?</h3>
- Red light- Indicator for the motorists to stop.
- Green-Signal for safety and word GO.
- Yellow- This signal let you know that the red signal is about to be displayed.
- when it's turned on, you can start slowing down to come to a stop in anticipation of red light.
- when we cannot stop safely at a yellow traffic light before entering an intersection, enter the intersection carefully and continue across.
Thus, we can conclude that, the option C is correct.

Since both cars move together after the collision, then this is an example of an inelastic collision. The formula for an inelastic collision is as follows:
m1u1 + m2u2 = (m1 + m2)v
Where:
m1 = mass of the first object
m2 = mass of the second object
u1 = initial velocity of the first object
u2 = initial velocity of the second object
v = final velocity
Substituting the given values to solve for v:
900*22 + 900*15 = (900 + 900)v
v = 18.5 m/s
Answer: The order is 2,1,5,4,3

The image to the left (with the disks on it)
Explanation:
Interference in any type of wave can be gotten in two forms, constructive interference, and destructive interference.
The constructive interference is between two waves with the same phase, that is, each crest and trough correspond with the crest and trough of the another getting as result a wave with twice the amplitude of the original one.
The destructive interference is between two waves out of phase, in which the crest of one cancels with the trough of another.
If light passes for a slit it will get a diffraction pattern in a screen, at which each bright pattern corresponds to a crest and a dark pattern to a trough, as a consequence of constructive interference and destructive interference in different points of its propagation to the screen.
The circular shape of the disks can be a representation of the wavefront and how the overlaps make constructive and destructive interference in order to get the diffraction pattern.
