A physical change involves a change in physical properties. Examples of physical properties include melting, transition to a gas, change of strength, change of durability, changes to crystal form, textural change, shape, size, color, volume and density.
Distance and displacement are hardly ever equal.
Remember that 'displacement' is the straight-line distance between
the start-point and the end-point, regardless of what path you followed
on the way.
So they're equal ONLY when the trip from start to finish was completely
in a straight line.

Answer:
The net force on the scooter is 95 N to the left.
Explanation:
Lizzie is pushing with 75 N of force to the left, so the force is a vector with 75N of magnitude and to the left.
Alex is helping with 20 N to the left, so the force is a vector with 20 N magnitude and to the left.
When we add vectors, vectors that point in the same direction add up and vectors that point in opposite directions are subtracted.
Hence, the net force is equal to:
F=75 N + 20 N=95 N
As both forces point to the left, the net force is also to the left.
Answer:
B)
Explanation:
Because like charges stick because they have sort of an interest in each other
