From the front door to his current position, Aaron's Distance is 4m. and his Displacement is 4m.
Distance is a measure of how far apart two objects or locations are using numbers. The distance can refer to a physical length in physics or to an estimate based on other factors in common usage. Sometimes, the symbol |AB| is used to represent the distance between two points.
A displacement is a vector in geometry and mechanics that have a length equal to the shortest distance between a point P's initial and final positions.
Given,
Length of path = 4m
Distance =?
Displacement =?
Distance is the length of the path and it has magnitude but no direction. The distance covered is 4m Displacement is the length of the path and it has magnitude and direction. Displacement is 4m towards the mailbox.

To solve this problem we will apply the concept of frequency in a string from the nodes, the tension, the linear density and the length of the string, that is,

Here
n = Number of node
T = Tension
= Linear density
L = Length
Replacing the values in the frequency and value of n is one for fundamental overtone



Similarly plug in 2 for n for first overtone and determine the value of frequency



Similarly plug in 3 for n for first overtone and determine the value of frequency



The energy an object has due to its motion is called kinetic energy.
Answer:
All atoms of an element are identical. The atoms of different elements vary in size and mass. Compounds are produced through different whole-number combinations of atoms. A chemical reaction results in the rearrangement of atoms in the reactant and product compounds.
HOPE THIS HELPED!!!!!!!!!!!!!!!!!!! XDDDDDDDDDDD
