Well if that’s the case and it wasn’t obvious you were using the power you could say things like being unseen while your doing it like a silent killer or maybe not having to rush in with your fists.a disadvantage would be that you could accidentally use your power and hurt an innocent person
Answer:
The magnetic flux density is 3 x 10⁵ Wb/m²
Explanation:
Given;
magnetic flux of each line of force, Ф = 30 Wb
area of the bar magnet, A = 1 cm² = 1 x 10⁻⁴ m²
The flux density of the magnet is the measure of the concentration of the magnetic flux per unit area. The unit is Wb/m² or Tesla.
B = Ф / A
B = 30 / (1 x 10⁻⁴ )
B = 3 x 10⁵ Wb/m²
Therefore, the magnetic flux density is 3 x 10⁵ Wb/m²
Answer:
kinetic energy does not change
Explanation:
you can use the formula for the kinetic energy of the electron and for the radius of the trajectory of an electron in a uniform magnetic field:
me: mass of the electron
B: magnetic field
q: charge of the electron
r: radius
By doing v the subject of the formula and replace it in the expression for the kinetic energy you obtain:
as youcan see, all parameters r, q, B and me are constant.
hence, the kinetic energy does not change
8 electron are needed for bonding
