In which applications are sound waves reflected? check all that apply. cleaning lenses detecting diseases destroying cancer cells locating damaged parts breaking down kidney stones monitoring fetal development

The correct answers are detecting diseases, locating damaged parts and monitoring fetal development.

Explanation:

Ultrasound is a sound wave with higher frequency. The frequency of ultrasound wave is higher than 20,000 Hz.

Ultrasound is a technology that uses high frequency sound waves to create images.

Sound wave is used to detect the damaged parts in the big machinery plants by sending the sound waves. If the sound wave gets reflected back then there is no flaws in the machine but it is not then there may be some damaged parts or cracks in that machine.

Ultrasound is used in medical imaging technique. The ultrasound machine transmits high frequency sound into body by using probe to get the images of the internal parts of the body. It helps in monitoring fetal development. It detects the diseases in the body like tumor.

Therefore, the applications of the sound waves reflected are detecting diseases, locating damaged parts and monitoring fetal development.

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
