I think the answer is B but the problem in this part is that the South American plate has moved over time. You see the difference?
Density of Earth: 5.514 g/cm³
Density of Jupiter: <span>1.326 g/cm³
1.326 g/cm³ / 5.514 g/cm³ </span>≈ <span>0,24
0,24 * 100 = 24%
Jupiter has 24% of earth's density.
(Density numbers are from internet, you may calculate with your own ones if u have )</span>
Wave speed = frequency * wavelength
Wave speed = 686 * 2.00
Wave speed = 1,372 (m/s)
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


Answer:
Light
Explanation:
The way a concave mirror works is that since it's concave, the light bounces off of each other. a convex mirror, it curved the opposite, and the mirror has no way to bounce off of itself.
