(a) The magnitude of the charge on sphere is 1.52 x 10⁻⁸ C.

(b) The total electric flux leaving surface of sphere is 1,717.86 Nm²/C.

(c) The electric field at surface of sphere is 91.82 N/C.

<h3>Charge on sphere</h3>

The charge on the sphere is calculated as follows;

Q = Aσ

where;

  • A is area of the sphere

A = 4πr²

A = 4π(1.22)² = 18.7 m²

Q = (18.7) x (8.13 x 10⁻⁶ x 10⁻⁴)

<em>note: 1 cm² = 10⁻⁴ m²</em>

Q = 1.52 x 10⁻⁸ C

<h3>Total electric flux</h3>

Ф = Q/ε₀

Φ = (1.52 x 10⁻⁸) / (8.85 x 10⁻¹²)

Φ  = 1,717.86 Nm²/C

<h3>Electric field at surface of the sphere</h3>

E = Ф/A

E = \frac{Q}{4\pi \varepsilon _0 r^2} \\\\E = \frac{1.52  \times 10^{-8} }{4\pi \times 8.85 \times 10^{-12} \times (1.22)^2} \\\\E = 91.82 \ N/C

KiRa [710]

Answer:

\frac{V_{e}}{V_{h}}=0.428*10^{2}

Explanation:

From conservation of energy states that

K_{i}+v_{i}=v_{f}+K_{f}\\ as\\K_{i}=0\\K_{f}=1/2mv^{2}\\ v_{i}=qv\\v_{f}=0\\So\\qv=1/2mv^{2}\\ v=\sqrt{\frac{2qv}{m} }\\ Velocity_{electron}=\sqrt{\frac{2qv}{m_{e}} }\\Velocity_{hydrogen}=\sqrt{\frac{2qv}{m_{h}} }\\\frac{V_{e}}{V_{h}}=\sqrt{\frac{\frac{2qv}{m_{e}}}{\frac{2qv}{m_{h}}}}\\\frac{V_{e}}{V_{h}}=\sqrt{\frac{m_{h}}{m_{e}} }\\\frac{V_{e}}{V_{h}}=\sqrt{\frac{1.67*10^{-27} }{9.11*10^{-31} } }\\\frac{V_{e}}{V_{h}}=0.428*10^{2}

Three 20.0 ohm resistors are
V125BC [204]

Answer:

6.67 ohm

Explanation:

From the question given above, the following data were obtained:

Resistor 1 (R₁) =20 ohm

Resistor 2 (R₂) = 20 ohm

Resistor 3 (R₃) = 20 ohm

Equivalent Resistance (R) =?

Since the resistors are arranged in parallel connection, the equivalent resistance can be obtained as follow:

1/R = 1/R₁ + 1/R₂ + 1/R₃

1/R = 1/20 + 1/20 + 1/20

1/R = (1 + 1 + 1) / 20

1/R = 3/20

Invert

R = 20/3

R = 6.67 ohm

Therefore, the equivalent resistance is 6.67 ohm.
