Answer:

Sound is produced when an object vibrates, creating a pressure wave.As the particles vibrate, they move nearby particles, transmitting the sound further through the medium. The human ear detects sound waves when vibrating air particles vibrate small parts within the ear.

Enter the general expression for an infinitesimal area element dA in spherical coordinates (r, θ, φ) using n as your outward-poi
Brut [27]

Answer:

dA can be written as shown below:

r^ dA = r^ r2 sinθdθdφ

Explanation:

r^ dA = r^ r2 sinθdθdφ

where dA is an infinitesimal area element taken on the surface of a sphere of radius, r, centered at the origin and r^ is the radial component of the radius which given the value for n.

A clay ball (mass = 0.25kg) has a rightward momentum of +1.75 kg∙m/s. A second clay ball (mass = 0.25 kg) has a leftward momentu
julia-pushkina [17]

1)

\begin{gathered} E1=\frac{1}{2}m_1v_1^2+\frac{1}{2}m_1v_2^2 \\ where: \\ m_1=m_2=0.25kg \\ v_1=7m/s \\ v_2=-7m/s \\ so: \\ E1=\frac{1}{2}0.25(7^2)+\frac{1}{2}0.25(7^2) \\ E1=6.125+6.125 \\ E1=12.25J \end{gathered}

Answer:

d. 12.25J

------------------------

2)

According to the conservation of energy:

\begin{gathered} E1=E2 \\ so: \\ E2=12.25J \end{gathered}

Answer:

b. 12.25

-------------------------------

3)

P1=m_1v_2+m_2v_2=+1.75-1.75=0

Answer:

d. 0 kg∙m/s

-----------------------------------------

4)

Using conservation of momentum:

\begin{gathered} P1=P2 \\ so: \\ P2=0 \end{gathered}

Answer:

b. 0 kg•m/s

Un satélite geoestacionario se encuentra a una distancia de 120.000 km sobre la superficie de Júpiter. Determine: a. El periodo
alex41 [277]

Answer:

a. El período de revolución = 36.000 segundos

si. La frecuencia de oscilación = 2,78 × 10⁻⁵ Hz

C. La distancia recorrida = 440017,75 km

re. La velocidad angular = 1.745 × 10⁻⁴ rad / s

La velocidad = 12,22 km / s

Explanation:

a. Dado que el satélite es un satélite geoestacionario, el período es el mismo que el período de revolución de Júpiter.

Por lo tanto;

El período, T de revolución del satélite = 10 × 60 × 60 = 36.000 segundos

El período de revolución = 36.000 segundos

b. La frecuencia de oscilación, f = 1 / T = 1 / 36,000 = 2.78 × 10⁻⁵ Hz

La frecuencia de oscilación = 2,78 × 10⁻⁵ Hz

c. Dado que el radio de Júpiter = 69,911 km, tenemos;

El radio de órbita, r = 69,911 km + 120 km = 70031 km

La distancia recorrida = 2 × π × r = 2 × π × 70031 = 440017.75 km

La distancia recorrida = 440017,75 km

re. La velocidad angular, ω = (Ángulo cubierto) / Tiempo = 2π / (36,000) = 1.745 × 10⁻⁴ rad / s

La velocidad angular = 1.745 × 10⁻⁴ rad / s

La velocidad, v = r × ω = 70031 × 1.745 × 10⁻⁴ = 12.22 km / s

La velocidad = 12,22 km / s
