Answer:
The wire length is 32 inches.
Explanation:
According to the question,
The pipe's length = 60 inches
The pipe's circumference = 4 inches
Now,
The wire wraps around the pipe for 8 complete turns.
Now, with 2πr = 4, we find that
r = 2/π
Thus,
The radius, r = 2/π
The wire's length can be calculated as,
Length = Number of turns x Circumference of the pipe
So, length of wire = 8 x 4 = 32 inches.
Consequently, the wire length is 32 inches.
<span>You are presented with a circuit that includes a 6.0-v battery, a 4.0-ohm resistor, a 0.60 microfarad capacitor, an ammeter, and a switch all connected in series. Your task is to determine the current reading once the switch is closed. Ohm's law should be used, which states V = IR where V signifies voltage, I indicates current, and R represents resistance.</span>
V = IR
I = V/R
I = 6 volts / 4 ohms
I = 1.5A
Upon closing the switch, the cathode side plate starts accumulating electrons if it was previously empty. As this process continues, the current diminishes. Eventually, when the capacitor reaches its maximum electron retention, the current will cease. An increased capacitance means a greater capacity for electron storage.
Respuesta:
Se pueden recargar.
Poseen una vida útil mayor.
Son reutilizables.
Explicación:
Las baterías de plomo-ácido y las pilas Leclanché son tipos de células electroquímicas.
Las pilas Leclanché son células primarias. Estas células producen reacciones químicas que generan corriente eléctrica de manera irreversible.
Por su parte, las baterías de plomo-ácido son células secundarias que permiten la reversibilidad de la corriente eléctrica generada.
Esto hace que las baterías de plomo-ácido sean reutilizables, con mayor durabilidad y un tiempo de vida más prolongado.
Response:
The horizontal span of Sosa is 276.526 ft or 84.28 meters.
Explanation:
As illustrated in the diagram, let point O denote Sosa's starting position. She travels 361 ft at a 50-degree angle relative to the horizontal.
sin 50 = 
0.7660 = h / 361
h = 276.526 ft
h = 84.28 meters
The horizontal distance of Sosa is 276.526 ft or 84.28 meters.
Answer:
a. β = 8.23 K
b. β = 28.815 K
Explanation:
The performance of the heat pump can be calculated using the formula
β = TH / (TH - TC)
a.
TH = 15 ° C + 273.15 K = 288.15 K
TC = - 20 ° C + 273.15 K = 253.15 K
β = 288.15 K / (288.15 K - 253.15 K)
β = 8.23 K
b.
TH = 15 ° C + 273.15 K = 288.15 K
TC = 5 ° C + 273.15 K = 278.15 K
β = 288.15 K / (288.15 K - 278.15 K)
β = 28.815 K
