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

answer:   you might love summer weather, but you don’t want it to feel like the sun is inside your car. but a hot car that just won’t seem to cool down might be a bigger of a problem than you think. your car relies on being at the right temperature.

explanation:

d

explanation:

v=uf/(u-f)

= 5.10/(5-10) convex lens has positive focal length

=50/-5

nah.   i'm just sleepy.

where’s the list ? the question is incomplete
