They are related because waves affect matter. Reflection, refraction, and diffraction. Reflection occurs when wave bounces back from a surface that they cannot pass through. Refraction occurs when waves bend as they enter a new medium at an angle and start traveling at a different speed.
Answer:
The final velocity of the vehicles will be -75km per hour (leftwards).
Explanation:
Let us call
,
mass and velocity of the truck ,
mass and velocity of the car, and
the final velocity of the vehicles.
The law of conservation of momentum states that

solving for
we get:

putting in numerical values


(<em>the negative sign indicates that the vehicles are moving in the leftward direction)</em>
or -75.8 km per hour.<em> </em>
Using the formula
for momentum your answer would come out to be:

Answer:
A) Have more coils of wire
F) Use a more powerful battery
Vf^2 = Vi^2 + 2ad
a= 34 m/s^2
Vi = 0 m/s
d = 3400m
Vf = 480.83 m/s
a=v/t
t=v/a
t=480.83/34
t=14.142 s
