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
Explanation:
Answer:
Density dependent factors include disease, competition, and predation. Density dependant factors can have either a positive or a negative correlation to population size
Explanation:
hope this helps ;)
Answer: It is a molecular compound. (2) It contains a metal. (3) It can conduct electricity as a solid.
Answer:
30gtts/min
Explanation:
To solve this problem we need to divide the volume(mL) and time(min) then multiply by the drop factor. Note that 1hr = 60min.
120/60 * 15 = 30gtts/min
Best of Luck!
