A block is attached to the end of a horizontal ideal spring and rests on a frictionless surface. The block is pulled so that the spring stretches relative to its unstrained length. In each of the following three cases, the spring is stretched initially by the same amount. Rank the amplitudes of the resulting simple harmonic motion in decreasing order (largest first). (a) The block is released from rest. (b) The block is given an initial speed . (c) The block is given an initial speed .

Answers

Answer 1

Answer:

The answer is "a, c and b"

Explanation:

Its total block power is equal to the amount of potential energy and kinetic energy.Because the original block expansion in all situations will be the same, its potential power in all cases is the same.Because the block in the first case has no initial speed, the block has zero film energy.For both the second example, it also has the [tex]v_o[/tex] velocity, but the kinetic energy is higher among the three because its potential and kinetic energy are higher.While over the last case the kinetic speed is greater and lower than in the first case, the total energy is also higher than the first lower than that of the second.The greater the amplitude was its greater the total energy, therefore lower the second, during the first case the higher the amplitude.

4. Un móvil viaja en línea recta con una velocidad media de 1200 cm/s durante 9 s, y luego con velocidad media de 480 cm/s durante 7 s, siendo ambas velocidades del mismo sentido: a) ¿cuál es el desplazamiento total en el viaje de 16 s? B) ¿cuál es la velocidad media del viaje completo?

Answers

Answer:

A) El desplazamiento total del viaje es 14160 centímetros.

B) La velocidad media del viaje completo es 885 centímetros por segundo.

Explanation:

A) El desplazamiento es el producto de la velocidad media por el tiempo. El desplazamiento total es la suma de desplazamientos asociados a cada velocidad media, entonces:

[tex]x = \left(1200\,\frac{cm}{s}\right)\cdot (9\,s)+ \left(480\,\frac{cm}{s} \right)\cdot (7\,s)[/tex]

[tex]x = 14160\,cm[/tex]

El desplazamiento total del viaje es 14160 centímetros.

B) La velocidad media del viaje es el desplazamiento total dividido por el tiempo total, es decir:

[tex]\bar v = \frac{14160\,cm }{16\,s}[/tex]

[tex]\bar v = 885\,\frac{cm}{s}[/tex]

La velocidad media del viaje completo es 885 centímetros por segundo.

the distance between a boy and a hill is 250 meters. if the boy shouts after how long will the echo be heard numerical problem​

Answers

Answer:

1.47 s

Explanation:

From the question,

s = 2d/t................... Equation 1

s = speed of sound in air, d = distance between the boy and the hill, t = time to hear the echo.

make t the subject of the equation

t = 2d/s............... Equation 2

Given: d = 250 meters

Constant: s = 340 m/s

Substitute these values into equation 2

t = (2×250)/340

t = 500/340

t = 1.47 s

Una botella vacía tiene una masa de 24.25g y de 86.55g completamente llena de agua, se vacia el agua y se llena nuevamente con 123.95g de solvente tetracloruro de carbono, ¿cual es la densidad del solvente?

Answers

Answer:

La densidad del tetracloruro de carbono es 1.990 gramos por centímetro cúbico.

Explanation:

La masa de agua contenida dentro de la botella es igual a la diferencia entre la masa pesada totalmente llena y la masa pesada totalmente vacía, es decir:

[tex]m_{w} = 86.55\,g-24.25\,g[/tex]

[tex]m_{w} = 62.3\,g[/tex]

Ahora, de acuerdo con la definición de densidad, la masa es directamente proporcional a la densidad, entonces, podemos calcular la densidad del solvente mediante la siguiente relación:

[tex]\frac{m_{x}}{m_{w}} = \frac{\rho_{x}}{\rho_{w}}[/tex] (1)

Donde:

[tex]m_{x}[/tex] - Masa del tetracloruro de carbono, en gramos.

[tex]m_{w}[/tex] - Masa del agua, en gramos.

[tex]\rho_{x}[/tex] - Densidad del tetracloruro de carbono, en gramos por centímetro cúbico.

[tex]\rho_{w}[/tex] - Densidad del agua, en gramos por centímetro cúbico.

Si sabemos que [tex]m_{x} = 123.95\,g[/tex], [tex]m_{w} = 62.3\,g[/tex] y [tex]\rho_{w} = 1\,\frac{g}{cm^{3}}[/tex], entonces la densidad del tetracloruro de carbono es:

[tex]\rho_{x} = \left(\frac{m_{x}}{m_{w}} \right)\cdot \rho_{w}[/tex]

[tex]\rho_{x} = 1.990\,\frac{g}{cm^{3}}[/tex]

La densidad del tetracloruro de carbono es 1.990 gramos por centímetro cúbico.

Answers

Explanation:

Given that,

The horizontal distance between the two nodes is 1.5 meters.

We need to find the wavelength of the standing wave.

If we know the distance between nodes and antinodes, then the equation is :

[tex]\dfrac{\lambda}{2}=D[/tex]

Where

[tex]\lambda[/tex] is the wavelength

So,

[tex]\lambda=2D\\\\=2\times 1.5\\\\=3\ m[/tex]

So, the wavelength of the standing wave is equal to 3 m.

A vertical piston-cylinder device initially contains 0.1 m^3 of air at 400 K and 100 kPa. At this initial condition, the piston is resting on a stop. The piston-cylinder device is connected to a supply line with air at 400 K and a pressure of 500 kPa. The valve between the supply line and the piston-cylinder device is opened and is left open until the pressure in the piston-cylinder device reaches 500 kPa. The piston is observed to start moving when the pressure in the cylinder is 200 kPa and the piston continues to rise until it reaches a second stop. At the second stop, the piston-cylinder volume is 0.2 m^3 . The final temperature and pressure in the piston-cylinder device are 440 K and 500 kPa, respectively.

Answers

Answer:

It follows that the magnitude in radians of one complete revolution (360 degrees) is the length of the entire circumference divided by the radius, or 2πr / r, or 2π. Thus 2π radians is equal to 360 degrees, meaning that one radian is equal to 180/π ≈ 57.295779513082320876 degrees.

30 kg sits on a table the acceleration due to gravity is 10 m/s^2 what force does the table exert on the television.
0.3N
3N
300N
600N

Answers

Answer:

300N

Explanation:

F=m×a

F=30kg×10m/s^2

F=300N

If 30 kilograms sit on a table the acceleration due to gravity is 10 meters/second², then the force exerted by the table on the television would be 300 Newtons,

Therefore the correct answer is option C.

What is acceleration?

The rate of change of the velocity with respect to time is known as the acceleration of the object.

As given in the problem If 30 kilograms sit on a table the acceleration due to gravity is 10 meters/second²,

the force exerted = mass × acceleration due to gravity

                       = 30 kilograms ×  10 meters/second²

                       = 300 Newtons

Thus, the force exerted by the table on the television would be 300 Newtons,

Answers

Answer:

w=42.2 x8.15 x cos40

w=343.93× cos 40

W=343.93 x 0.76

W=261.38 J

Work done on the object will be 264.83 J

What is work done ?

Work done  is the product of the component of the force in the direction of the displacement and the magnitude of this displacement.

given :

F = 42.2 N

let , x  = 40°

horizontal distance (s) = 8.15 m

Work done = F s cos (x)

                  = F * s * cos (x)

                  = 42.2 * 8.15 * cos 40° = .766

                  =  343.93 * 0.77
