I need help solving it and I need a step by step explanation.

A mosquito beating its wings

produces sound waves with

a frequency of 700 Hz and a

wavelength of 0.5 m.

frequency: f=700 Hz

wavelength: X= 0.5 m

a. Find: wave speed: s

s=f

b. Substitute:

s = 700 x 0.5 = 350

c. Determine the units:

units of s = (units of f) x

(units of X)

(Hz) x (m)

= (1/s) x (m) = m/s

11. Use a Simple

Equation How fast are the

sound waves of the beating

Read this passage about Amelia Earhart.

Amelia Earhart was born July 24, 1897, in Kansas. She was an adventurous and fun-loving child. That adventurous spirit remained as she grew older. One day in 1920, after going on a plane ride, she was determined to fly planes. She worked at any job she could find to save up for flying lessons, which cost $1,000. At one point, she worked as a nurse’s aid and a social worker. Six months after receiving flying lessons, Amelia bought her own plane, and she flew as high as 14,000 feet, which set a world record for female pilots. A short time afterward, Amelia became the sixteenth female to earn a pilot’s license. In 1928, an opportunity arose for Amelia to participate in a transatlantic flight across the Atlantic Ocean as a copilot. This experience later came in handy when she became the first woman to fly solo across the Atlantic in 1938. She received many honors for this achievement, such as the Distinguished Flying Cross from Congress.

As Amelia approached her fortieth birthday, she was planning her biggest trip yet: She wanted to be the first woman to fly around the world. Of course, she needed a lot of help to make this happen. She made a first attempt that failed and damaged her plane. But Earhart was not one to give up, so she made another attempt at the ground-breaking mission. She did make some progress by flying 7,000 miles to New Guinea but did not make it to her next stop, Howland Island. Sadly, Earhart’s plane disappeared, and, despite search and rescue attempts, she was never found. To this day, Earhart is known and celebrated for her bravery, persistence, and commitment to aviation.

A yearbook page for Amelia Earhart includes "Amelia's Pet Peeve: Not Being Adventurous." Which image would best illustrate this?

A plane.
A bungee jumper.
Three skydivers.
A man reclining in a beach chair.
