Explanation:
Explanation:
It is given that,
Frequency of diagnostic ultrasound, f = 3.82 MHz = 3820 Hz
The speed of the sound in air, v = 343 m/s
(a) We need to find the wavelength in air of such a sound wave. Let it is given by λ₁
i.e. 
(b) If the speed of sound in tissue is 1650 m/s .
Hence, this is the required solution.
The net force on the system:
F = m₂g - m₁gsin(∅)
F = 39.5 x 9.81 - 43 x 9.81 x sin(30)
F = 176.58 N
Now, we use F = ma to find the acceleration on each mass.
F = m₁a₁
a₁ = 176.58 / 43
a₁ = 4.11 m/s²
F = m₂a₂
a₂ = 176.58 / 39.5
a₂ = 4.47 m/s²
<span>The answer is "0.5N".
According to the question;
P1=P2
so,
F1/A1= F2/A2
P=(F/A)
A1=100mm</span>²
<span>
F1= 10N
A2= 5mm</span>²
<span>
F2= ?
F2= ((F1 x A2)/A1)
= ((10 x 5) /100)
=50/100
=0.5N</span>
