Question

working of SONAR
Rutherford atomic model

Answer 1

Answer:

Sonar is simply making use of an echo. When an animal or machine makes a noise, it sends sound waves into the environment around it. ... Whales and specialized machines can use reflected waves to locate distant objects and sense their shape and movement. The range of low-frequency sonar is remarkable.

Explanation:

Rutherford's model shows that an atom is mostly empty space, with electrons orbiting a fixed, positively charged nucleus in set, predictable paths. This model of an atom was developed by Ernest Rutherford, a New Zealand native working at the University of Manchester in England in the early 1900s.
