I'm pretty your it's magnetism though. Like magnets
Responder:
- Volumen del bloque = 60cm³
- Densidad = 5g / cm³
Explicación:
Dada la dimensión del bloque
AB = 4 cm, BC = 2.5 cm y BF = 6 cm
Volumen del bloque = Largo × Ancho × Alto
Volumen del bloque = AB × BC × BF
Volumen del bloque = 4 × 2.5 × 6
Volumen del bloque = 60cm³
Dada la masa del bloque = 300 gramos
Densidad = Masa / Volumen
Densidad = 300g / 60cm³
Densidad = 5g / cm³
Algunos materiales que tienen una densidad de 5g / cm³ o cercanos son radio, germanio y europio con densidades de 5g / cm³, 5.3g / cm³ y 5.24g / cm³ respectivamente.
Answer:
Check Explanation
Explanation:
Ampere's Law gives the expression for the magnetic field produced by current in a current carrying material.
Mathematically, it is explained that the product of permeability and current is equal to the sum of the dot product of the magnetic field in the direction of the length elements and the length elements.
μ₀I = ∫ B.dl (note that this integral is around the entire loop of current carrying material)
This law is valid for infinite current carrying wires because the magnetic field around such infinite current carrying wire is symmetrical.
The magnetic field around a finite length of wire is non-symmetrical and the current isn't continuous.
For Ampere's Law to work, the magnetic field around the wire must be symmetric, for straightforward computation and the current in the wire needs to be continuous, not cut short at the edges which makes the field around the wire non-symmetrical.
So, this condition is interlinked.
Hence, it is evident that only option A is absolutely correct.
Options C and D on their own aren't totally correct, but in conjunction with option E, they are correct.
Hope this Helps!!!
