A loudspeaker converts electrical energy into the kinetic energy of the speaker. This kinetic energy is transferred to air, and

the motion of the air is the sound that people hear.

<span>It all starts from a radio with a loudspeaker . It produces and converts electrical energy and make this a formed of kinetic energy coming out of the speaker. Then, when this kinetic energy is moving and transferred to surroundings or air, it will let people feel the motion being created by the air. Finally, it reaches the people and hears this as sound. 

This is an example on how we trace the transformation of on signal from radio and how it reaches to people as sound or as a music.</span>

A block with mass m = 5.6 kg is attached to two springs with spring constants kleft = 35 N/m and kright = 52 N/m. The block is p
sergeinik [125]

Answer:

the magnitude of the net force on the block is 18.27 N

Explanation:

given information:

mass, m = 5.6 kg

spring constant kleft, k_{l} = 35 N/m

spring constant kright, k_{r} = 52 N/m

x = 0.21 m

the magnitude of the net force on the block. F

F = - kx

  = - (k_{l}+k_{r}) x

  = - (35+52) (0.21)

  = - 18.27 N

Air is cooled and

becomes denser.

Denser air sinks.

The process repeats, producing a (i wasn't sure about this one)

Air is heated and becomes less dense.

Less dense air rises.

Un zapato de golf tiene 10 tacos cada uno con un área de 0.01 pulgadas en contacto con el piso suponga que el camino hay un inst
iren2701 [21]

Responder:

12374550,527 N / m²

Explicación:

Dado que:

Número de tacos = 10

Área de cada montante = 0.01 in²

Peso total de la persona = 180 libras

Usando la relación:

Presión = Fuerza / Área

La fuerza ejercida es el producto de la masa y la aceleración debido a la gravedad.

Masa = 180 libras = 81,47 kg

Aceleración por gravedad = 9,8 m / s²

Área total = (número de montantes * Área por montante) = (10 * 0.01) = 0.1 pulg²

Conversión a m²:

0,1 pulg² = 6,452 * 10 ^ -5 m²

Por lo tanto,

Presión = (81,47 * 9,8) / (6,452 * 10 ^ -5)

Presión = 798.406 / 0.00006452

Presión = 12374550.527 N / m²
