The collision of the two waves would bring force and that would make the new wave smaller
Answer:
The axial force is 
Explanation:
From the question we are told that
The diameter of the shaft steel is 
The length of the cylindrical bushing 
The outer diameter of the cylindrical bushing is 
The diametral interference is 
The coefficient of friction is 
The Young modulus of steel is 
The diametral interference is mathematically represented as

Where
is the pressure (stress) on the two object held together
So making
the subject

Substituting values


Now he axial force required is

Where A is the area which is mathematically evaluated as

So 
Substituting values


A student uses a meter to measure 120 coulombs flowing through a circuit in 60 seconds. The electric current in this circuit will be 2 A
Current is a flow of electrical charge carriers, usually electrons or electron-deficient atoms. The common symbol for current is the uppercase letter I. The standard unit is the ampere, symbolized by A.
current = charge / time
given
time = 60 seconds
charge = 120 Coulombs
current = Q / T = 120 / 60 = 2 A

Answer: Solid
Explanation: There are 3 major state of matter - solid, liquid and gas.
Among the 3 state, solid has a fixed volume while liquid takes the volume of its container. When gas is compressed, it takes the volume of its container likewise.
