If you don't put Physics as the school subject, your question will not get the attention of any physics tutors. Please do as Ms. Sue instructed you above. Also, make sure you indicate what you have done about solving your question, too.

This is not an answer to your question but I want to point out that no one can answer your question with units. 10 what? 2.8 what? I suggest you repost th question and include ALL of the question instead of part of it.

Does that look like a complete question to you? Before you learn how to figure out answers in physics, you must first learn what constitutes a question, and a sentence.

I presume the question is trying to get you to calculate the distance travelled by the squirrel. In which case start with a diagram. My answer to the question, would, however, be 2.3 m vertically from the ground as the question does not state the displacement being asked for.

One of the first things you need to learn about physics is how to use data to answer a question. You have provided a lot of data but have failed to ask a question.

In the first question, you did not provide the frequency. Your answer to the second question is correct. In the third question, the frequency remains the same under water and (1500 m/s)/(frequency) is the new wavelength.

Add the derivatives of each term. Apply the rule that the drivative of a*t^n is n*a*t^(n-1), is a is a constant. 5/sqrt(t) can be written 5*t^(-1/2), so for that one, a = 5 and n = -1/2 This was not a physics question. It is a beginning calculus question
