Answer:
R=0.0438 Ω
Explicación:
1) Hallar el área o sección del conductor de cobre, usando esta fórmula:
A=π.r² (Pi x radio al cuadrado)
Debido a que conocemos el diámetro (1.5mm) su radio es la mitad de esto es decir 0.75mm, y lo sustituimos en la fórmula:
A=π.(0.75mm)²
A=π(0.5625mm²)
A=1.7671mm²
2) La resistividad del cobre es: rho = 0,0172 y la incluimos en la fórmula siguiente:
R=p
R=0,0172Ω x
Simplificamos:
R=
El resultado es:
R=0.0438 Ω

Answer:
coefficient green : 2.4865
exponent (yellow) : 16
Explanation:
Answer:
is missing
Explanation:
In a nuclear reaction, the total mass and total atomic number remains the same.
For the given reaction:

To calculate A:
Total mass on reactant side = total mass on product side
4 + 9 = 12 + A
A = 1
To calculate Z:
Total atomic number on reactant side = total atomic number on product side
2 + 4 = 6 + Z
Z = 0

Hence, missing is
