Answer:
<em>radius of the loop = 7.9 mm</em>
<em>number of turns N ≅ 399 turns</em>
Explanation:
length of wire L= 2 m
field strength B = 3 mT = 0.003 T
current I = 12 A
recall that field strength B = μnI
where n is the turn per unit length
vacuum permeability μ = 
= 1.256 x 10^-6 T-m/A
imputing values, we have
0.003 = 1.256 x 10^−6 x n x 12
0.003 = 1.507 x 10^-5 x n
n = 199.07 turns per unit length
for a length of 2 m,
number of loop N = 2 x 199.07 = 398.14 ≅ <em>399 turns</em>
since there are approximately 399 turns formed by the 2 m length of wire, it means that each loop is formed by 2/399 = 0.005 m of the wire.
this length is also equal to the circumference of each loop
the circumference of each loop = 
0.005 = 2 x 3.142 x r
r = 0.005/6.284 = 
= 0.0079 m =<em> 7.9 mm</em>
Hi!
The correct option is B.
<h3>Explanation</h3>
Evolution is a biological phenomena which descries how the heritable characteristics of a species change over successive generations. These characteristics change as a result of a mutation, natural selection or genetic recombination (to list a few).
Darwin's theory of evolution explained how this phenomena occurs with respect to natural selection. The theory goes on to explain how a species diverges from a common ancestor into two or more different species (meaning different species may have common ancestor). This is a slow process as it can take thousands of years.
Hope this helps!
Answer:
(Fuerza de repulsión/Repulsive force)
Explanation:
La fuerza ejercida entre las dos partículas se calcula por la Ley de Coulomb (The force exerted between the two particles is determined by Coulomb's Law):
Donde (Where):
- Constante electrostática, medido en 
(Electrostatic constant, measured in ).
, 
- Magnitudes de las cargas de cada partícula, medidos en Coulombs. (Magnitudes of charges from each particle, measured in Coulombs).
- Distancia entre las partículas, medida en metros.
La fuerza electrostática es (Electrostatic force is):
Dado que las partículas tienen el mismo signo de carga, la fuerza es de repulsión. (Given that both particles have the same charge sign, the force is of repulsive nature)
The answer will be D. Solid
This is due to solids having little movement/vibrations allowing for the particles to be compact. They don't get to have much freedom.
Most to least will
Both NPN and PNP transistors consist of a base composed of an N-type material.
