physics
The lowest note on a grand piano has a frequency of 28.1 Hz. The entire string is 2.00 m long and has a mass of 440 g The vibrating section of the string is 1.90 m long. What tension is needed to tune this string properly?

physics
Thank you so very much Damon!

A 121 cm-long, 3 g string oscillates in its m = 3 mode with a frequency of 154 Hz and a maximum amplitude of 5.0 mm. What are the wavelength and the tension in the string?

physics
Half the wavelength is .325 but I am not getting the right answer

physics
a standing wave oscillating at 115 Hz on a string. The distance d between the two walls equals 65 cm. What is the wave speed?

History Thesis....
can anyone help me is this a good thesis if not what can I change I am lost.... Harold Grey’s Little Orphan Annie comic strip provided a message that helped people get through the Great Depression, it is suggested that this comic strip provided America with understanding ...

Math
Explain how a child who has not yet developed base-ten concepts understands quantities as large as say 85. Contrast this with a child who understands these same quantities in terms of base-ten groupings.

physic
Vertical T = force of burgular Find inclined tension using Ay = A*sin(theta) Find horizontal tension using Pythag: A^2 = Ay^2 + Ax^2 Ax is the horizontal tension

I need to make a holder for a raw egg out of straws so when it is dropped from 8 feet. it will not break I need design ideas.

Calculus
limit of ((1/x) - (1/|x|) as x approaches x from the left side. i have no idea how to approach this problem.
