How much heat is given off when 210.0g of water at 0 degrees freezes into ice?
Sergio [31]

In the freezing physical change, when 210.0 g of water a 0 degrees freezes into ice, it gives off 71.0 kJ of heat.

<h3>What is freezing?</h3>

It is a physical change in which liquids give off heat to form solids.

We have 210.0 g of water at 0°C. We can calculate the amount of heat given off when it freezes into ice using the following expression.

Q = ΔH°fus × m

Q = 0.334 kJ/g × 210.0 g = 70.1 kJ

where,

  • Q is the heat released.
  • ΔH°fus is the latent heat of fusion.
  • m is the mass.

In the freezing physical change, when 210.0 g of water a 0 degrees freezes into ice, it gives off 71.0 kJ of heat.

El radio de un tarro es de 0,07 m. Si la masa de un niño es de 50 kg y la de cada uno de sus zancos es de 1 kg, ¿cuál es la pres
inessss [21]

Answer:

La presión ejercida sobre el suelo mientras el niño está parado en un pie es 33127,874 pascales.

Explanation:

Después de una rápida investigación por internet, concluimos que este enunciado está incompleto. La versión completa se describe a continuación:

<em>En la imagen se observan los pies de tres niños que caminan en zancos hechos de tarros con arena en el interior. El radio del tarro es de 0,07 metros. Si la masa del niño es de 50 kilogramos y la de cada uno de sus zancos es de un kilogramo, ¿cuál es la presión que se ejerce sobre el suelo cuando el niño está parado en un pie? </em>(Nota: No se ha podido encontrar la citada imagen)

El enunciado hace referencia a aquel juego infantil de poner cada uno de los pies sobre un zanco hecho de una lata metálica. Ambos zancos están unidos mediante una cuerda accionada por las manos y brazos. En este caso, uno de los niños mantiene el equilibrio sobre uno de sus pies. La fuerza generadora de la presión ejercida sobre el suelo es el peso conjunto del niño y los zancos.

Asumiendo que la fuerza se distribuye uniformemente sobre la superficie inferior del zanco, el cual tiene forma de cilindro recto, la presión ejercida sobre el suelo (p), en pascales, queda descrita por la siguiente fórmula:

p = \frac{W}{A} (1)

p = \frac{(m_{N}+2\cdot m_{Z})\cdot g}{\pi\cdot r^{2} } (1b)

Donde:

m_{N} - Masa del niño, en kilogramos.

m_{Z} - Masa del zanco, en kilogramos.

g - Aceleración gravitacional, en metros por segundo al cuadrado.

r - Radio del tarro, en metros.

Si sabemos que m_{N} = 50\,kg, m_{Z} = 1\,kg, g = 9,807\,\frac{m}{s^{2}} and r = 0,07\,m, entonces la presión ejercida sobre el suelo mientras el niño está parado en un pie es:

p = \frac{(50\,kg + 2\,kg)\cdot \left(9,807\,\frac{m}{s^{2}} \right)}{\pi \cdot (0,07\,m)^{2}}

p = 33127,874\,Pa

La presión ejercida sobre el suelo mientras el niño está parado en un pie es 33127,874 pascales.

Engineers can determine properties of a structure that is modeled as a damped spring oscillator, such as a bridge, by applying a
Kazeer [188]

The value of spring constant and the oscillator's damping constant is

K= 6605.667008, b= 0.002884387

Explanation:

For Weakly damping spring oscillator

K/m = W_0^2     (at resonance)

K= mW_0^2

=0.206 * ( 2π * 28.5) ^2

=0.206 * (2π)^2 * (28.5)^2

K= 6605.667008

F = - bV

b= -F/V = -F/ -W_0 * m

=F/W_0 * m

= 0.438N / 2π * 28.5 * 0.848

b= 0.002884387

Read through the and calculate the predicted change in kinetic energy of the oblect compared to 50 kg ball traveling at 10 m/s .
Sliva [168]

Answer:

A 50 kg ball traveling at 20 m/s would have 4 times more kinetic energy.

A 50 kg ball traveling at 5 m/s would have 4 times less kinetic energy.

A 50 kg person falling at 10 m/s would have the same kinetic energy.

Explanation:

hope this helps:)

Which describes the electric field at the center of a ring of uniform negative charge?.
Bingel [31]

Answer:

A negatively charged particle -q is placed at the center of a uniformly charged ring, where the ring has a total positive charge Q as shown in the following figure. The particle, confined to move along the x axis, is moved a small distance x along the axis ( where x << a) and released. Show that the particle oscillates in simple harmonic motion with a frequency given by,
