The frequency of the ultrasound is (converting in Hz)
f=4.077 MHz=4.077 \cdot 10^6 Hz
while the speed of sound in the body is
v=2.31 km/s = 2310 m/s

We can calculate the wavelength of the ultrasound in the body by using the relationship betwen frequency, wavelength and speed of the wave:
\lambda =  \frac{v}{f}= \frac{2310 m/s}{4.077 \cdot 10^6 Hz}=5.67 \cdot 10^{-4} m

Two ice skaters stand together. They push off and travel directly away from each other, the boy with a velocity of v = +0.35 m/s
DIA [1.3K]

Answer:

-0.55m/s

Explanation:

Given that: For the boy

Weight = 745N

Velocity = +0.35 m/s

Mass of the boy = ?

g = 9.81m/s^2

W = mg

745 = m×9.81

m = 75.94kg

For the girl

Given that:

Weight = 477 N

g = 9.81m/s^2

m = ?

W = mg

477 = m×9.81m/s^2

m = 48.62kg

To solve for the v of the girl, the two has to add up

48.62kg×v + 75.94kg×+0.35 m/s = 0

48.62v + 26.579 = 0

48.62v = - 26.579

v = -26.579/48.62

v = -0.5466

v = -0.55m/s

Hence, the velocity of the girl is -0.55m/s.

The negative sign is as a result of the two of them moving is opposite direction.
