Answer:
I believe its: A wave with a shorter wavelength has higher frequency
The work performed on an object is the force multiplied by the distance it is moved, provided the movement is parallel to the force. Since that is the case here, we can get the work by W=Fd=1900N x 0.23m = 437J. This energy is used to split the wood.

Think about rubbing your hands together- the friciton produces heat
Answer:
The edge length of the empty space between atoms that reside along [100] directions in a BCC crystal of Cs metal is 0.612 nanometers
Explanation:
For Body centered cubic structure (BCC) crystal in direction [100], the edge length of unit cell is calculated with the formula below;
X = 
Where;
X is the edge length of the empty space between atoms
R is the radius of the cesium atom = 0.265 nanometers
X = (4*0.265)/(√3)
X = 0.612 nanometers
Therefore, the edge length of the empty space between atoms that reside along [100] directions in a BCC crystal of Cs metal is 0.612 nanometers
