What is the wavelength of an earthquake wave if it has a speed of 3 km/s and a frequency of 6 Hz?

A wave has a frequency of 34 Hz and a wavelength of 2.0 m. What is the speed of the wave? Use . A. 17 m/s B. 36 m/s C. 0.059 m/s

mel-nik [20]

F= (speed)/(wavelength)

Therefore, speed = Frequency x wavelength
V = 68m/s

Una persona A tiene cierta cantidad de masa y una persona B tiene la mitad de masa de la persona A ¿como es el peso de B respect

musickatia [10]

Answer:

El peso de la persona B es la mitad del peso de la persona A.

Explanation:

El peso de la persona B puede calcularse con la siguiente ecuación:

$P_{B} = m_{B}g$ (1)

En donde:

$m_{B}$ : es la masa de la persona B

g: es la gravedad

Dado que la persona B tiene la mitad de la masa de la persona A, tenemos:

$m_{B} = \frac{m_{A}}{2}$ (2)

En donde:

$m_{A}$ : es la masa de la persona A

Al introducir la ecuación (2) en (1) nos queda:

$P_{B} = \frac{m_{A}}{2}g$ (3)

Sabemos que el peso de la persona A está dado por:

$P_{A} = m_{A}g$ (4)

Entonces, al introducir la ecuación (4) en (3) tenemos:

$P_{B} = \frac{P_{A}}{2}$

Por lo tanto, el peso de la persona B es la mitad del peso de la persona A.

Answer:

The hotter the substance, the more its particles move, and the higher its thermal energy. ... Heat. The heat from a heater. *Let's think about that cup of hot chocolate. ... Some matter changes from solid to liquid to gas as its particles heat, vibrate and separate. ... Boiling a kettle is an example of both thermal and kinetic energy.

Consider a wire of length L = 0.30m that runs north-south on a horizontal surface. There is a current of I = 0.50A flowing north

ankoles [38]

Answer:

Part a)

$F = 4.6 \times 10^{-6} N$

Part b)

$F = 8.2 \times 10^{-2} N$

Explanation:

Part a)

As we know that the magnetic force on the current carrying wire is given as

$F = i(\vec L \times \vec B)$

so we have

$F = iLB sin\theta$

$F = (0.50)(0.30)(0.5 \times 10^{-4}) sin38$

so we have

$F = 4.6 \times 10^{-6} N$

Part b)

Now magnetic field is changed to 0.55 T

so we will have

$F = (0.50)(0.30)(0.55) sin90$

$F = 8.2 \times 10^{-2} N$

Troyanec [42]

<span>If coal is stacked near mines, the most likley thing that will happen is that rain watter will carry contaminants in coal into durface water. When rain falls on coal, it erodes it just like any other rock. So amounts of coal can be washed out of its holding area and into surface *and* groundwater. Correct answer:D</span>
