6. What happens to the frequency if you increase your wavelength and keep wave speed the same?
7. How can you change the amplitude of the waves?
8. What is the relationship between period and frequency?
9. What kind of waves are shown above? Btw is in another answer that I did .
10. If the wavelength of wave B is 0.45m, what is the wave speed?
I uploaded the other paper btw for 9 and 10

Arock is dropped from a cliff and reaches the ground in 2.70s. at the same time another rock is thrown horizontally from the same height with initial x velocity of 0.95 m/s. what distance will in x will the second rock cover?

The membrane surrounding a living cell consists of an inner and an outer wall that are separated by a small space. assume that the membrane acts like a parallel plate capacitor in which the effective charge density on the inner and outer walls has a magnitude of 7.0 × 10-6 c/m2. (a) what is the magnitude of the electric field within the cell membrane? (b) find the magnitude of the electric force that would be exerted on a potassium ion (k+; charge = +e) placed inside the membrane.

How is zig zagging a form of acceleration?
