An external force of 5N is applied to a go-kart that is opposite it’s direction of travel for 5 seconds. What is the resulting momentum of the go-kart?

Options:

A: 25 kg m/s

B: 100 kg m/s

C: 975 kg m/s

Awave that is traveling fast can be said to have a high a. frequency b. speed c. wavelength d. amplitude e. period f. none of these

If frequency goes down, what happens to wavelength? does it get shorter or longer?

50.)the diagram below represents the wave fronts produced by a point source moving to the right in a uniformmedium. observers are located at points a and b. compared to the wave frequency and wavelength observed at point a, the wave observed at point b has a(1) higher frequency and a shorter wavelength(2) higher frequency and a longer wavelength(3) lower frequency and a shorter wavelength(4) lower frequency and a longer wavelength
