Answer:
Isaac walked a distance of 5 blocks, and his displacement was 3 blocks north.
Explanation:
Distance is what he covered from the beginning, while displacement was what he covered in a specific direction
When the temperature of a substance is increased, the kinetic energy of the particles of the substance is increased as well.
This can lead to thermal expansion such as an increase in length of the substance or increase in volume of the substance.
This can also lead to change of state of the substance, for example change of state from solid to liquid or from liquid to vapor.

I can only help you with the last two questions from lesson 5.01
-Because light is the fastest thing in our universe you can calculate the distance by how much time light has to take in order to travel that distance which is light years
-Light years, and every measurement you can think of. Except light years are the easiest most efficient way to measure distances
Answer:
The top of the window is 0.5 m below the sill of the upper window
Explanation:
We have the time the pot takes to fall a distance y- yo = 2.0 m and g = 9.8, from this we can calculate the velocity of the pot when it just reached the top of the window in question. Take the positive y direction to be downward
y-yo=vo*t+I/2gt^2
vo=(y-yo-I/2gt^2)/t
vo=3.138 m/s
The flowerpot falls from rest and we have the velocity it gains until it reaches the top of the window below, from this information we can get the distance between the sill and the top of the window below.
v^2=vo^2+2g(y-yo)
y-yo=(v^2-vo^2)/2g
= 0.5 m
The top of the window is 0.5 m below the sill of the upper window
