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

Select all the correct answers. which changes will increase the rate of reaction during combustion? decreasing the area of contact between the reactants adding more oxygen to the reaction removing heat from the reaction changing the reactants from solid form to powdered form lowering the exposure of the reactants to air

The great sandini is a 60.0-kg circus performer who is shot from a cannon (actually a spring gun). you don’t find many men of his caliber, so you him design a new gun. this new gun has a very large spring with a very small mass and a force constant of 1100 n/m that he will compress with a force of 4400 n. the inside of the gun barrel is coated with teflon, so the average friction force will be only 40.0 n during the 4.00 m he moves in the barrel. at what speed will he emerge from the end of the barrel, 2.50 m above his initial rest position?
