A charge of 3 nC is uniformly distributed around a ring of radius 10 cm that has its center at the origin and its axis along the
Step2247 [10]

Answer:

W=2.592*10^{-7} J

Explanation:

GIVEN DATA:

Charge 3 nC

Radius of ring is 10 cm

A point charge 1 nC

Distance of point charge is 2.5 m

We know that voltage is calculated as

V(0) =\frac{KQ}{r}

      =\frac{(9*10^{-9})(3*10^{-9})}{0.1}

V = 270 V

At x = 2.5m

r = \sqrt{(0.1^2+2.5^2)}

r = 1.581 m

V(2) = \frac{(9*10^9)(3*10^{-9})}{1.581}

V(2) = 10.801 V

Work done is calculated as

W= q(dV)

W = (1*10^{-9})(270 - 10.80)

W=2.592*10^{-7} J

Un depósito de gran superficie se llena de agua hasta una altura de 0,3 m. En el fondo del depósito hay un orificio de 5 cm2 de
ahrayia [7]

Answer:

a) El caudal de salida del chorro es 1.213\times 10^{-3}\,\frac{m^{3}}{s}.

Explanation:

a) Asúmase que el tanque se encuentra a presión atmósferica y que la sima del tanque tiene una altura de 0 metros. La rapidez de salida del chorro del depósito se determined a partir del Principio de Bernoulli, cuya línea de corriente entre la cima y la sima del tanque queda descrita por la siguiente ecuación:

\Delta z = \frac{v_{out}^{2}}{2\cdot g}

Donde:

\Delta z - Diferencia de altura, medida en metros.

g - Constante gravitacional, medida en metros por segundo al cuadrado.

v_{out} - Rapidez de salida del chorro, medida en metros por segundo.

Se despeja la rapidez de salida del chorro:

v_{out} = \sqrt{2\cdot g \cdot \Delta z}

Si g = 9.807\,\frac{m}{s^{2}} y \Delta z = 0.3\,m, entonces la rapidez de salida del chorro es:

v_{out} = \sqrt{2\cdot \left(9.807\,\frac{m}{s^{2}} \right)\cdot (0.3\,m)}

v_{out} \approx 2.426\,\frac{m}{s}

Ahora, la cantidad de líquido que sale del depósito por unidad de tiempo se obtiene al multiplicar la rapidez de salida del chorro por el área transversal del orificio. Esto es:

\dot V_{out} = v_{out}\cdot A_{t}

Donde:

v_{out} - Rapidez de salida del chorro, medida en metros por segundo.

A_{t} - Área transversal del orificio, medido en metros cuadrados.

\dot V_{out} - Caudal de salida del chorro, medido en metros cúbicos por segundo.

Dado que v_{out} = 2.426\,\frac{m}{s} y A_{t} = 5\,cm^{2}, el caudal de salida del chorro es:

\dot V_{out} = \left(2.426\,\frac{m}{s} \right)\cdot (5\,cm^{2})\cdot \left(\frac{1}{10000}\,\frac{m^{2}}{cm^{2}}  \right)

\dot V_{out} = 1.213\times 10^{-3}\,\frac{m^{3}}{s}

El caudal de salida del chorro es 1.213\times 10^{-3}\,\frac{m^{3}}{s}.

A 300 g bird is flying along at 6.0 m/s and sees a 10 g insect heading straight towards it with a speed of 30 m/s. The bird open
Gelneren [198K]

Answer:

(a): The bird speed after swallowing the insect is V= 4.83 m/s

(b): The impulse on the bird is I= 0.3 kg m/s

(c): The force between the bird and the insect is F= 20 N

Explanation:

ma= 0.3 kg

va= 6 m/s

mb= 0.01kg

vb= 30 m/s

(ma*va - mb*vb) / (ma+mb) = V

V= 4.83 m/s (a)

I= mb * vb

I= 0.3 kg m/s  (b)

F*t= I

F= I/t

F= 20 N (c)

How did the end of the ice age cool the earth
ANEK [815]

In general, it is felt that ice ages are caused by a chain reaction of positive feedbacks triggered by periodic changes in the Earth's orbit around the Sun. The last ice age ended about 12,000 years ago. The next cooling cycle would be expected to start about 30,000 years or more into the future.
