Asf Institute answered |
- Spinels have a general formula AB2O4 and are classified as either normal or inverse.
- In a normal spinel, A2+ ions occupy the tetrahedral sites, and B3+ ions are in octahedral sites.
- In an inverse spinel, half of the B3+ ions and all A2+ ions occupy octahedral sites, while the remaining ... more
- CoFe2O4 is inverse because Co2+ prefers octahedral sites.
- FeFe2O4 (magnetite) is also inverse with Fe3+ ions distributed as described.

What is the dimension of px cap= h/2πi . Del/ del x?
|
|
Anirban Kapoor answered • Feb 17, 2024 |
Dimension of px cap = h/2πi
Explanation:
• The given expression represents the momentum operator in the x-direction, which is denoted by px.
• The dimension of momentum is [M^1 L^1 T^-1]. In this case, we have an additional factor of h/2πi, where h is Planck's constant and i is the imaginary unit.
• To determine the dimension of px, we need to find the dimension of h/2πi.
• The dimension of h is [M L^2 T^-1], where M stands for mass, L for length, and T for time.
• The dimension of 2π is dimensionless.
• The dimension of i is also dimensionless.
• Therefore, the dimension of px cap = h/2πi is [M^1 L^1 T^-1].
Del/del x
Explanation:
• The symbol del/del x represents the partial derivative with respect to the x-coordinate.
• It is used to calculate how a function changes concerning changes in the x-direction while keeping other variables constant.
• The del/del x operator is commonly used in mathematics and physics, especially in the field of quantum mechanics.
• It helps in determining the rate of change of a function along the x-direction.
• The del/del x operator is essential for understanding the behavior of functions in multi-dimensional spaces and is a fundamental tool in calculus.
