Answer: The correct option is C.

Explanation:

The sound wave is reflected back after striking from the barrier. This is called the reflection of the sound.

When the sound wave incidents on the barrier then it is called incident wave.

When the sound wave gets reflected back from the barrier then it is called reflected wave.

Ultrasound imaging is a medical technique which is used to take the image of the internal parts of organ of the body.

Echolocation is the process which is used by several species. It is used by bats to locate its prey. It is the biological SONAR.

Therefore, echolocation and ultrasound imaging are same as they both use the reflection of sound waves.

A mass m is attached to a string connected to a force sensor on a rotating platform. The platform’s angular velocity, ω, can be

makkiz [27]

Answer:

The mass m is 0.332 kg or 332 gm

Explanation:

Given

The platform is rotating with angular speed , $\omega =8.5\, \frac{rad}{sec}$

Mass m is moving on platform in a circle with radius , $r=0.20\, m$

Force sensor reading to which spring is attached , $F=4.8\, N$

Now for the mass m to move in circle the required centripetal force is given by $F=m\omega ^{2}r$

=> $4.8=m\times 8.5 ^{2}\times 0.20$

$=>m=0.332\, kg$

Thus the mass m is 0.332 kg or 332 gm
