I have made another clan. The Car Clan. To be in this clan, simply change your pfp to car and you're in my clan.

As a car drives with its tires rolling freely without any slippage, the type of friction acting between the tires and the road is 100) a) static friction. b) kinetic friction. c) a combination of static and kinetic friction. d) neither static nor kinetic friction, but some other type of friction. e) it is impossible to tell what type of friction acts in this situation.

How does changing the frequency affect the energy of the wave?

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