How does the material through which a wave travels affect the wave? Give evidence and reasoning for your claim. Hint: Think about the questions that we just answered about the speed of sound in air. Example Sentence Frames
Claim: A material like can change the of a wave.
Evidence: I know this because (use data with specfic numbers).
Reasoning: This means that materials like are able to directly affect the of waves.

b. a lightning bug, plug of grass, and a worm

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
