Answer:
C. remix
Explanation:
A is wrong because the prefix ir- means not
B is wrong because the prefix un means not
C is correct because re means again
D is wrong because over means too much
Answer:
The correct option is: Nonmetal
Explanation:
Non-metals are the chemical elements that are generally present in the gaseous state at room temperature and have low electrical and thermal conductivity. These elements are non-magnetic and tend to have low density, boiling point and melting point. Non-metals have high electronegativity and ionization energy and react by sharing or gaining electrons from the other elements.
<u>Therefore, the given material is most likely a non-metal.</u>
Answer:
l3/l = 2
Explanation:
Suppose B1 is the magnetic field due to cable 1 and B2 is the field due to cable 2. Therefore, the magnitude of the field at a distance from the cable is equal to:
B = (uo*I)/(2*pi*r)
B1-2 = (B1^2 + B2^2)^1/2 = ((((uo*I)/(2*pi*r)^2 + (uo*I)/(2*pi*r)^2))))))^1/2 = (2^1/2)*(uo*l)/(2*pi*r)
From this equation we can say that the direction of the field will be from the corner that is empty and cable 3:
B3 = B1-2
(uo*l3)/(2*pi*(2^1/2)*r = (2^1/2)*(uo*l)/(2*pi*r)
From here we have that the relationship between both currents will be equal to:
l3/l = 2
